Polyurethane resin composition curable by radiation, and process for producing a polyurethane resin composition curable by radiation.

摘要

Polyurethane resin composition curable by radiation, and process for producing a polyurethane resin composition curable by radiation. The present invention provides compositions of resins polyurethane radiation curable with reduced viscosity and processes for P. Roduzir such compositions.The resin composition curable by radiation comprises the polyurethane product of contact (a) at least one composoto containing active hydrogen with X active hydrogen atoms, (b) at least poliisocianato possessing f features isocyanate and (c) at least one molecule pequen The curable by radiation having an active hydrogen atom; where f and X are each.A number of 242 2; and where at least 80% by weight of the composition comprises a main x moles of poliisocianato and (F - 1) x moles of small molecule curable by radi ~ tion per mole of compound containing active hydrogen.
