Polyset® CR-20® is a low-rise, two-component polyurethane foam adhesive engineered for speed and simplicity. Polyset® CR-20® is ideal for adhering a variety of insulation boards, cover boards, as well as fleece back membranes to various substrates in both new and re-roof applications. This product comes in self-contained, ready to dispense kits consisting of A and B cylinders, a Handi-Gun® dispensing unit and Colorwise® Temperature Warning Nozzles. These portable kits make it easy to access hard-to-reach areas, plus provide faster application on open roofs. Polyset® CR-20® kits feature simple-to-use pressurized cylinders versus large mechanical proportioners, cumbersome caulk-type dispensers or carts. No extra power source is required.
