Synthesis of High_Performance Two_Component Acrylic Polyurethane Coatings

：High-performance two-component acrylic polyurethane coatings were synthe-sized with multihydroxyl acrylic resins and hexamethylene diisocyanate (HDI) biuret. In this paper, the coating structure and preparation process were described, and the effect of some factors on the performance of the coatings were also discussed. Experimental results show that coatings are of excellent comprehensive performance and promising future.
