Polyisocyanate wikipedia

WebTwo-pack epoxy/isocyanate finishes require separate solutions of high molecular weight epoxy resin and polyisocyanate adduct as the two components; the epoxy resin must be in alcohol-free solvent since the curing reaction is predominantly with in-chain hydroxyl groups on the epoxy resin. One-pack finishes can be formulated with blocked isocyanates. Webic amine with aliphatic polyisocyanate). Polyaspartic ester-based polyurea topcoats are non-yellowing and exhibit good outdoor weathering and long pot life. The moderately fast reactivity, com-bined with the relatively low viscosity of the polyaspartic ester compounds, al-lows for a broader range of applications in two-component coatings.
