Describes the basic differences in major types of urethane surface coatings commercially available. Illustrates considerable variation in chemical resistance of commercial formulas in two-package or catalyzed urethane group. Describes superior resistance of catalyzed urethanes to softening by high-solvency organics as compared to commercial epoxyamine coatings. Illustrates urethane retention of flexibility and impact resistance after weathering exposures as compared to commercial catalyzed epoxies. Describes briefly several types of urethane coatings that are being developed. 5.4.5
