Allophanate modified polyisocyanates |
摘要 |
A composition that includes isocyanate group containing compounds that include on average i) a NCO functionality less than or equal to 3.5; and ii) from 1.5 to 8 percent by weight, based on the isocyanate containing compound, of allophanate groups; and which is substantially free of uretdione groups. The composition can be used in two component elastomeric coating compositions that include a component A the above-described composition and a component B that includes a compound containing one or more functional groups that are reactive with isocyanate groups. The elastomeric coating compositions can be used to coat substrates.
