Adhesives
COLTACK
The insulating adhesive COLTACK contains polyurethane and bitumen resin. It is compatible with all types of insulating material and resists wind uplift. COLTACK successfully passed Factory Mutual (FM) testing. Consult your representative for the recommended mixtures.
For a cleaner and effortless application, SOPREMA has developed the COLTACK APPLICATOR and the COLTACK TWIN APPLICATOR. All you have to do is install the adhesive container, pierce some holes, adjust the flow, and it is ready. The adhesive is applied at an equal and constant flow rate, guaranteeing perfect insulation adhesion.
DUOTACK
DUOTACK is a low-rise polyurethane two-part adhesive, used to attach insulating panels, vapour barriers and asphaltic boards. To avoid curing and sealing problems often associated with two-part products, DUOTACK’s components are contained in two-cartridge packaging. During application, the components blend and react in the supplied mixing tip. No drying time is required, and installation is neat and clean.
DUOTACK’s greatest strength is its use at any temperature. It can be applied in winter temperatures, on condition that it is stored at a temperature higher than 20°C (70°F) 12 hours before use. DUOTACK successfully passed Factory Mutual (FM) wind uplift testing. Consult your representative for the recommended mixtures.
COLPLY
For membrane application with adhesive, COLPLY is a superior solution. COLPLY is composed of SBS modified bitumen and solvent. Use the Brush Grade version for horizontal application and Trowel Grade for vertical application such as flashing. 
SOPRASTOP
The adhesive SOPRASTOP, made of fast-evaporating solvents, bitumen and SBS polymers, is used to adhere SOPRASTOP vapour barrier paper to metallic bridging and to seal the end-of-roll joints. Its unique formulation provides excellent adhesive strength and is fast curing. SOPRASTOP is also used to fasten various other building materials, such as gypsum, concrete and wood.
