DESMOPHEN NH 1220 is a low-viscosity, solvent-free liquid aminofunctional co-reactant that is commonly used for the formulation of tough but flexible, lightfast and highly reactive two-component polyurethane coatings. DESMOPHEN NH 1220 can be used as co-reactant for Desmodur® N products to provide polyurethane coatings with excellent mechanical properties ideal for applications that require durability against weathering and abrasion. The coatings formulated using DESMOPHEN NH 1220 exhibit high chemical and water resistance along with good adhesion making them suitable for long-lasting protective and decorative surface applications.
