Abstract
Research on manufacturing the kapur (Dryobalanops spp.) particle board has been conducted using the mixture of clover leaf oil by products and tannin after being mixed with phenol and formaldehyde as adhesives. Particle board was prepared by molding process while pressing and heating. Particle board measured by using SNI 01-2105-1991 have physical properties i.e. density, water content, thickness swelling meet the standard whereas the mechanical properties i.e. modulus of elasticity, modulus of rupture, internal bond strength, and screw holding strength do not meet the standard. Ultra-violet cured polyester coatings on particle board have pencil hardness of 2B — 2H, medium gloss (36— 58 %), adhesion meet ASTM D 2571-71, and most failure patterns occur on particle board part. In general, polyester coats do not resist against 10 % sodium hydroxide solution
