Marine Caulk All-In-One Sealant and Adhesive
Bondseal 1128 marine caulk is a high performance marine sealant and adhesive that's moisture curing and provides an extremely durable bond when filling gaps, joints and cracks. It's unique rheology makes it easy to apply with a standard caulking gun, yet still retains excellent non-sag properties and great initial tack ideal for bonding metals such as stainless steel and aluminum.
Bondseal 1128 polyurethane adhesive features an exceptionally low isocyanate content, meaning it's safer to use than traditional commercial-grade polyurethane sealants and adhesives.
Bondseal 1128 Marine adhesive and sealant excels in use above and below the waterline, and has very good resistance to fading, ageing and cracking due to extended ultraviolet light exposure. Bondseal 1128 polyurethane sealant is paintable once skin forms, remains permanently flexible, has great impact and cut resistance while providing a 100% waterproof seal.
