| 摘要 |
A two-package air-drying coating system resistant to strong organic solvents, free from toxic heavy metals and excellent, for example, as a primer for adhering urethanes or epoxy enamels to previously painted steel, is based upon a rheologically desirable mixture of (1) plate-like filler, e.g., talc, (2) carbon black, and (3) barium lanolate with a binder composed of a polyol and a polyisocyanate crosslinking agent.
