Solfre 2466 adhesive is part of the Solfre 2 range of two-component polyurethane adhesives meeting the exacting industrial standards in a new climate of environmental awareness. The adhesive has exceptional adhesion to metallic substrates whilst maintaining the unique properties associated with the Solfre 2 range. This product was developed for application by roller coating, but now with recent developments of the application equipment it can also be spray or bead applied.
Soflre2 2466 Polyurethane Adhesives is used across a range of applications including architectural panels, insulation panels and for building panels for use in clean rooms, modular buildings, and cold storage such as walk-in refrigerators.
Solfre 2466 with its exceptional metal adhesion has found use in the manufacture of metal cladding panels, and even in the most stringent applications such as aluminium honeycomb panels. The metallic adhesion has proved a real advantage to users giving them a level of adhesion normally associated only with epoxy adhesives, together with the flexibility and application techniques of polyurethane adhesives with short cure cycles.

- Mix Ratio: 1:1 by Volume
- Packaging: 50ML Twin Cartridge (Includes static mixing tip. One per cartridge)
Coverage: Between 3 and 10 m²/Kg depending on the porosity and uniformity of the substrates being bonded. Only one substrate requires coating with Solfre 2466.
Substrate Preparation: All surfaces should be free of contamination by dust, grease, oils or release agents. Substrates should be checked for contamination by mould release or cutting agents. Metals should be degreased prior to bonding as a precaution. Cleaning solutions, if used, must be allowed to evaporate before application of the adhesive. Some metals (untreated aluminium and galvanised steel) may require priming to achieve a satisfactory permanent bond.
Application: Solfre 2466 if supplied in a twin cartridge should be mixed by dispensing through a MC08-32 static mixer. For bulk application Chemique’s engineers have developed a two part metering system where both components are accurately transferred from the bulk containers to a manifold where they are combined in the precise ratio and thoroughly mixed prior to discharging. The manifold and mixer are manually flushed clean when application stops for extended periods.
Bonding Range and Pressure: Solfre 2466 should be used as it is supplied. All panels or composites should be held together throughout the curing process. This is best accomplished in a press with up to 10 p.s.i. pressure, however this will depend upon the strength of the substrates and core materials used.
