Title:
ELECTRONIC BEAM CURABLE POLYURETHANE COMPOSITION
Document Type and Number:
Japanese Patent JPS5956418
Kind Code:
A
Abstract:
Improved electron beam curable compounds are prepared by mixing 100 weight parts of (1) polyurethanes prepared from polymeric polyols, organic diisocyanates and polyethers having terminal hydroxyl and unsaturated groups, or terminal hydroxyl and pendant unsaturated groups with (2) 1 to 25 weight parts of an acrylate or alkacrylate terminated polyurethanes prepared by reacting isocyanate terminated prepolymers of hydroxyl terminated polymers with hydroxyl-terminated acrylates or alkacrylates. Compositions of this blend may be crosslinked or cured in a few seconds by electron beam to provide an improved stable coating that can be cured to a variety of hardnesses. These polyurethanes combined with phenoxy resins also form particularly useful binder systems for magnetic tape.
