prepared from ordinary polyether polyols by high-pressure catalytic hydrogenation with ammonia.
mainly used for Spray Polyurea Elastomer, RIM products, epoxy resin curing agent, etc. The Spray Polyurea Elastomer prepared by Amino-terminated Polyether and isocyanate has high strength, high elongation, friction resistance, corrosion resistance and aging resistance, and is widely used in waterproof, anticorrosive and wear-resistant coatings on the surface of concrete and steel structures, protective and decorative coatings for other components. Amino-terminated Polyether used in epoxy resin curing agent, can improve the toughness of products, a large number of used in the manufacture of epoxy resin crafts.
low toxicity. Galvanized iron drum packaging, 200kg per barrel. Store in a cool, dry, and ventilated place.
Amine types curing agents are derivatives from ammonia (NH3). They are named according to the number of amines in a molecule, like: mono-, di-, tri- and polyamines. According to the type of hydrocarbon involved, they are classified as:
Aromatic amines have better chemical resistance than aliphatic amines.
Melamine curing agent will react with the OH functionalities at high temperature (above 140°C). Mainly used in stoving curing systems, this reaction can be accelerated using a catalyst.
