Abstract:

The present invention is directed to a non-aqueous composition curable by UV radiation broadly comprising a mixture of two UV curable urethane acrylates. The invention is also directed to a coating process using such composition. One of the urethane acrylates is the reaction product of an isocyanate and a specific OH functional lactone ester (meth)acrylate. The other urethane acrylate is the reaction product of an isocyanate and a specific hydroxy functional (meth)acrylate.

Abstract:

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.
