A design of plastic industrial products was manufd. by setting the synthtic resin with the pearl flakes. Thus, "polycoat8000A" and "H510" were mixed with each other at the mixture ratio of 1:1-1:2 and the above mixture was stirred with pearl flakes at the mixture ratio of 100:1.5 to make the plastic art products. In the manufg. process, the working temp. was maintained below 28OC and the mixture was poured into the mold at a speed of 2.5-4 l/hr.
