#1 Health & Safety
Solvent-based adhesives contain harmful ingredients known as volatile organic compounds (VOCs). These chemicals can be harmful to not only the environment, but also human health. Upon application, these toxic substances can be inhaled, causing damaging health problems such as dizziness, respiratory issues as well as headaches.
#2 Environmental Impact
Solvent-based adhesives therefore not only cause detrimental effects to those who handle them, but also harm our precious environment when dangerous chemical gasses are released into the air. The solvents used in these adhesives are typically derived from fossil fuels, which, when applied in an adhesive, the solvents evaporate into the air, contributing to air pollution, negatively contributing to climate change. Solvent-free adhesives are a much better alternative as they do not release harmful polluting gasses, whilst never comprising on bond strength. When there are so many fantastic solvent-free adhesive alternatives on the market, it seems crazy to continue using such damaging products.
#3 Performance & Longevity
It’s a no brainer to choose a product that doesn’t negatively impact your health, but especially when those products achieve better performance standards. Compared to their harmful counter-part, solvent-free adhesives actually provide stronger bonds, have better water resistance and are much more flexible. Not only this, but they can be used on a wider range of materials, including plastics, metals and ceramics and even have a longer lifespan. Solvent-free adhesives maintain their strength and flexibility over time, without drying out or becoming brittle, making them the ideal choice for long-term applications. You can therefore achieve amazing results with a wide range of substrates, without compromising on long lasting results!
#4 Improved Quality
Interestingly, because solvent-free adhesives don’t contain nasty VOCs, they actually improve the quality of your finished product. It turns out that this is because those unnecessary, harmful solvents actually weaken the adhesive bond. What’s more, solvent-free adhesives additionally have better heat resistance as well as resistance to moisture and other chemicals. Solvent-free adhesives also have reduced freight costs - why pay higher freight charges if you can have a higher performing, safer and cheaper product delivered for less?
The conclusion…
Overall, solvent-free adhesives are a better choice for both human health and the environment, they can provide better performance and compliance with regulations and offer a safer, longer-lasting, and higher quality alternative to solvent-based adhesives.
*Top tip
Look out for the MAS Green Certified label that will tell you when adhesive products have no harmful VOC’s. Using these products could qualify users for LEED credits. By contributing to healthy and more sustainable building projects, you can build credits, showing a commitment to the environment by reducing contribution to global climate change, enhancing our health, protecting and restoring water resources and enhancing biodiversity.
The question remains… when are you going to make the switch to Turftak solvent-free adhesives?

#1: Where will you use your sealant?
The first step when deciding about what type of sealant or caulk to use, is to think about where your sealant will be used. The type of project you are undertaking will determine the best sealant option...
#2: What color do you want your sealant?
Another important factor to consider is where you are using the caulk. If the sealant is visible, for use in the bathroom for example, then you may prefer a white sealant. For many caulking jobs, it is most important that it is not noticeable. All three types of sealants are available in white, as well as gray and black. Alternatively, for other projects you may refer a clear sealant which is available in silane modified polyurethane sealants, as well as green and beige. Additionally MS polymer sealants are also available in mahogany and teal, perfect for marine projects.
#3: Solvents and hazards
Both silane modified polyurethane sealants and MS polymer sealants are great solvent free options. Isocyanates are highly reactive chemicals. The reaction to moisture releases carbon dioxide molecules which can form bubbles that reduce the final strength of the sealant. Polyurethane sealants do contain isocyanates, whereas silane modified polyurethane sealants and MS polymer sealants are hazard free!
#4: How much water resistance is needed?
Both silane modified polyurethane sealants and MS polymer sealants can be used and applied to wet surfaces. Additionally they can be overpainted when wet. This provides a useful option for outdoor projects and bathroom or kitchen applications.
#5: Is the sealant exposed to excessive sunlight?
If the area where you will be applying the sealant will be exposed to consistent sunlight, such as around the windows of RVs, you will want to consider using a sealant that is UV stable. Both the silane modified polyurethane sealants and MS polymer sealants offer UV stability, preserving the brilliant color of your sealant.
#6: Viscosity types
Silane modified polyurethane sealants and MS polymer sealants are both available in low and high viscosity grades, whereas polyurethane sealants are available as a high viscosity product.
Polyurethane sealants or PU sealants are generally a slow cure, high viscosity moisture cure sealant. They are based on technology utilizing organic material, and are well known for their high performance bonding and sealing properties in both indoor and outdoor environments.
Mechanical and adhesion strength are often much higher than traditional silicone sealants, and its properties can be tailored for nearly any use. Due to polyurethane sealants’ hardness, adhesion strength, thixotropy, and flexible performance, they have been used for decades in the construction, automotive, truck building and RV manufacturing industries. Polyurethane sealants and relied on for their strength, durability and flexibility and are a great option for these industries as they do not degrade over time! It is important to keep in mind however, that polyurethane sealants contain isocyanates and cannot be overpainted when wet or applied to wet surfaces.
Silane modified polyurethane sealants are generally known as hybrid sealants, giving polyurethane strength combined with the flexibility you get from silicones. They are part of a new generation of isocyanate-free, high strength bonding and sealing technology. These polyurethane based sealants use a modified silane polymer as its chemical base, which is known for offering superior adhesion and green strength when compared to traditional silicone based adhesives and sealants.
These fantastic sealants were originally developed in Japan as a very flexible, strong construction sealant that was able to handle Japan’s frequent earthquakes. MS polymer sealants have evolved into a diverse performance-driven range, offering superior sealing and bonding solutions covering many industries. There are many benefits to using MS polymers include their solvent and isocyanate free formulations, strong yet flexible bonds while sealing lines, odorless formulation, and ability to be painted wet on wet, as well as incredible UV resistance.

One of the most well-known epoxy adhesives are the two-part epoxies, also called two-part epoxy glues or two-part epoxy resin. These glues are available in liquid form and in thick pastes that harden when dry; both kinds are manufactured with hardeners that activate when mixed with the resin.
Two-part epoxy glues, like the new Massetak Two-Component Epoxy Adhesive from Chemique Adhesives, are great in situations where you need a strong adhesive that will resist high temperatures, humidity, mild vibration and other extreme conditions. They come in a wide variety of grades for use on wood, metal, concrete, plastics and more.
For RV and motorhome delaminated flooring repairs, Axil FloorFix kit utilises a two-part epoxy adhesive that fixes the root cause of damage deep down in delaminated floor panels and walls, by revitalising structural integrity.
Here are some of their main advantages.
1.) Bonds A Variety Of Materials - Epoxy adhesives and resins are extremely popular due to their ability to bond a wide variety of materials including metals, timber, plastics, and more.
2.) High Strength Adhesive - Epoxy adhesives are incredible strong and have an extremely good ability to hold dissimilar substrates under sustained loads making them ideal structural adhesives.
3.) Chemique resistance - Epoxy Adhesives have excellent chemical and environmental resistance. Many formulations have a paste consistency which can be either bead applied with an application gun or troweled onto surfaces. Epoxy adhesives have great gap filling properties and provide excellent seals against harsh chemicals. Some epoxies can tolerate processing oil on the substrate and still obtain satisfactory bond strength!
4.) Controlled Bonding Process - Two-part epoxy adhesives offer convenience and control over the bonding process brining flexibility to your manufacturing process. The bond only activates once the hardener and and resin combines resulting in the curing process.
There are a few disadvantages to using two-part epoxy.
1.) Adhesive Cost - The first disadvantages is that epoxy adhesives are generally expensive when compared to other options on the market. Two-part epoxy can be a more expensive way to bond things together than many other adhesives, including acrylic glue and solvent glues and polyurethane adhesives.
2.) Bond Integrity - Without modifications and exacting procedures in place, cured epoxies can be brittle. This holds especially true in environments that see aggressive vibrations. Although epoxies have good vibration resistance, some adhesives like polyurethane outpace performance and bond strength in this area.
3.) Precise Mix Ratios - Working with two-part epoxy adhesives often means precision and care need to be taken when it comes to mixing ratios. If you mix too much, or too little of one component the bond may not cure properly if there is any bond integrity to be found at all. Chemique Adhesives does a great job combatting this with pre-measured epoxy kits and cartridge systems!
A wide variety of two-part epoxy adhesives and glues is used in a range of industrial and domestic environments. They are known for their high bond strength to a wide variety of substrates. From bonding and sealing in structural environments, to gap filling in production two-part epoxy can bring strength and flexibility of application to your manufacturing process or your next home project.

]]>Two-part polyurethane adhesives are a type of chemical bonding system that utilizes a urethane and a hardener that are generally separated into two pouches or containment compartments. Unlike their single component counterparts that cure using environmental moisture, two-part polyurethane adhesives only activate through a chemical reaction that beings once both components are combined. Having the bonding process begin in this manor provides room for the creation of precision curing rates through customizing formulations, or by tailoring the mixing ratio to the curing requirements needed. This is vastly different from one-part polyurethane adhesives, which generally require environmental moisture to start the bonding process and to tune the curing rates.
Use cases for two component polyurethane adhesives are wide and vary across many industries. Two-part polyurethane adhesives are well suited for assembling a wide variety of dissimilar materials, notably porous materials (concrete, plaster, etc.), metals, glass and several thermoplastic materials and composites. At Chemique Adhesives, our most popular use case for two-component polyurethane adhesives is in the manufacture of composite panels, including aluminum honeycomb panels, RV wall panels, refrigeration panels, and structural insulated panels.
Strength: Two-component (two part) adhesives are incredibly strong and durable without the brittleness often found in epoxies adhesives, and cyanoacrylates. Though mixing is a requirement, the used of mixing nozzles and premeasured kits make this process a breeze for the end user. In manufacturing environments, mixing is accomplished through automated processes controlled by sophisticated pumping systems.
Controlled Curing: Another popular advantage to using two-part polyurethane adhesives is that they cure at room temperature without the need for heated presses. Though pressing and clamping is still recommended, the bond is based on the original chemical reaction and not off any application of heat. This allows end users to utilize lower cost vacuum presses, weighted presses, or shop clamps based on the job.
Elasticity: For transportation panel manufacturers, the main attractive features two-part polyurethane adhesive offers are in the final assembly. Polyurethanes have high resistance to impacts and vibrations, thanks to their elasticity (the product can be used to assemble materials with different coefficients of thermal expansion), and its impressive mechanical performance (the product can bond and seal at the same time).
Waterproof: Once fully cured polyurethane bonds are waterproof, making it a good adhesive choice for marine environments, and outdoor projects. Popular uses include laminating marine panels in boat building and yacht manufacturing.
Solvent Free: Two component polyurethane adhesives like Chemique’s Solfre2 are solvent-free and contain no free isocyanates. This means that they’re environmentally friendly, safer to use indoors, and safer for the installers that apply the adhesives. Chemique still recommends the use of extraction systems if you spray polyurethane adhesives.
