WANNATE HB-75B can be used as the hardener component for lightfast two-component polyurethane coatings with high resistance to chemicals and weathering, very good gloss retention and outstanding mechanical properties.

POLYETHERAMINE MA 2200 is a difunctional primary amine. Its mainchain is consisted of repeating oxypropylene units. Average molecular weight = 2000 g/mol.

POLYETHERAMINE MA 223 is a difunctional primary amine. Its mainchain is consisted of repeating oxypropylene units. Average molecular weight = 230 g/mol.

Luna PTSI-P is used in the formulation of polyurethane products as a reactive additive with low viscosity. Luna PTSI-P prevents moisture related problems by reacting with trace moisture. Excess water reacts with Luna PTSI-P towards the corresponding carbamic acid, which undergoes immediate decomposition to form carbon dioxide and the relatively inert p- toluenesulfonamide, which is commonly used as a plasticizer.
