DESMODUR NZ 300 is a polyisocyanate hardener that provides excellent mechanical properties, durability and weather resistance. It is used as a curing agent in two-component coating systems. DESMODUR NZ 300 reacts with polyols to form a highly crosslinked network structure providing long-lasting, abrasion resistant and chemical resistant coatings. The aliphatic structure of DESMODUR NZ 300 makes the coatings lightfast and UV resistant suitable for outdoor applications withstanding weathering for years. DESMODUR NZ 300 based coatings are ideal for flooring, infrastructure and industrial applications requiring high performance protective coatings.
