专利汇可以提供Plastisol composition专利检索,专利查询,专利分析的服务。并且PURPOSE: To provide a plastisol compsn. with good bonding to the coated surface of articles (e.g., the surface of undercoat formed by acrylic coating) at relatively low temp., by incorporating vinyl chloride resins, plasticizers, and particular tackifying agents.
CONSTITUTION: A mixture of a blocked urethane prepolymer (e.g., prepolymer yielded by reacting polyfunctional polyols having a MW for each hydroxyl group of about 250W2,000 with org. diisocyanates and then converting into blocked adducts by ε-caprolactum, etc.) and a curing agent (e.g., nitrogen-contg. polyol, amino alcohol or fatty acid alkanolamide) in an equivalent ratio of about 1: 0.05W3 is used as a tackifying agent; namely, about 10W50pts.wt. vinyl chloride (co)polymer, about 10W50pts.wt. plasticizer (e.g., dioctyl phthalate), and about 1W7pts.wt. said tackifying agent are mixed together.
