Phosphate Ester Monomer Products
Five in-house grades span mono-, di- and multifunctional structures, enabling selection by acid value, colour, viscosity, flexibility and application.
Quick selection: KM2110 for the strongest metal and glass anchoring; KM2120 for light colour and low yellowing; KM2130 for flexibility and humid-heat resistance; KM2140 for low acid value and high peel strength; KM2160 for high crosslink density and abrasion resistance.
