ウレタン粘着剤
Document Type and Number:
Japanese Patent JP6480176
Kind Code:
B2
Abstract:
Disclosed is a urethane adhesive comprising a urethane resin obtained by blending a polyol with an isocyanate compound; a plasticizer; and a stabilizing agent, wherein the polyol comprises a polyether polyol, and the plasticizer comprises a castor oil based compound. Releasability of the adhesive does not degrade even though the adhesive is kept under a severe condition such as at a high temperature and at a high humidity, and the adhesive is excellent in compatibility with regard to the plasticizer and the stabilizing agent. Since the urethane adhesive is excellent in releasability with regard to a glass plate, a polarizer for liquid crystal displays and so on, it is useful as an adhesive for surface protective films which are used for windowpanes, mobile phones and the like.
