SWD8031 is polymerized by the reaction of polyaspartic and polyisocyanate. Since polyaspartic ester is aliphatic sterically hindered secondary amine, and the selected curing component is aliphatic polyisocyanate, the formed coating membrane has high gloss and color retention property, suitable for long-term outdoor use. When the secondary amine group reacts with isocyanate group, it will form a high crosslink density, cross-interpenetrating polymer chain network, that also makes it has excellent physical and chemical performance. It is an updated innovation of anticorrosion product.
