Short Description

Systems with B1, B2 and B3 incombustibility according to DIN 4102 standard, with applied densities of 35 to 44 kg\/m, in metal-to-metal, metal-to-membrane (PVC-TPU) applications, roof and used for facade coatings. It can be used in structures such as factories, shopping malls, cold rooms, and prefabricated parts. It consists of five components: polymix, isocyanate, catalyst, solids and blowing agent.
