CORRUGATED PLATE AND FLAT PLATE OF UNSATURATED POLYESTER RESIN

摘要

PROBLEM TO BE SOLVED: To provide a resin composition giving highly transparent FRP corrugated plates and FRP flat plates with high weatherability and gloss retention. SOLUTION: The corrugated plate or flat plate of unsaturated polyester resin is made from a composition comprising (A) an unsaturated polyester 1.528-1.54 in refractive index and (B) a polymerizable unsaturated monomer. A cured product of 3 mm thick from the composition is characterized in having a gloss retention of≥60% and a color difference of≤20. COPYRIGHT: (C)2004,JPO
