Abstract

It was researched to be alternative of TGIC type hardener with human hazard element as PT 910 mix powder paint with hardener. Generally PT 910 was compared with TGIC & Epoxy resin of hardener to be used at thermosetting powder paint. We inquired a property of matter for paint through Gel time, glass transition temperature, melting point and a property of matter for film through a property of adhesion, a property of tolerance, softness, gloss, acid-resistant, alkali-resistant, salt water spray-resistant, facilitation climatic. When PT 910 is used of hardener, it was shown the excellent results in gel time, softness, salt water spray-resistant, fracilitation climatic and the similar results in melting point, a property of tolerance, a property of adhesion, gloss, acid-resistant, alkali-resistant, as compared with the powder paint used by TGIC hardener. The glass transition temperature was little low. But there was slightly different results. After the study results, we reached the conclusion that thermosetting powder used by PT 910 is alterative to by TGIC hardener.
