CAS NO.54553-90-1 MF:C9H10N2 SYNONYM:PYROMELLITIC ACID,DI(PHENYLIMDAZOLINE)SAL GENERAL DESCRIPTION MATT HARDENE TP68 is used for pure epoxy resin , epoxy\ polyester hybrid powder coatings to achieve coatings with matt surface having excellent mechanic quality and wonderful appearance. TYPICAL PROPERTIES Appearance Fine white powder Purity ≥99% Melting range 200-225℃ RECOMMENDEN FORMULATION FOR APPLICATION Gloss 60° 5--6 20 40 70 Epoxy(663U) 54.5 39.7 35.7 31.8 Polyester(acidity:25-35mgOH/g) / 14.8 20.8 26.7 TP68 5 5 3 1 Filler(BaSo4\CaCo3) 40 40 40 40 Levelling agent 0.5 0.5 0.5 0.5 Carbon black 0.5--1 0.5--1 0.5--1 0.5--1 CURING CONDITION 180°C 20-25 minutes,190°C 10-12 minutes,200°C 8-10 minutes APPLICATION Mainly used as Curing Agent for polyester powder coating, also used to manufacture electrical insulation materials, laminated sheetings, printed cruts, tools, adhesives, stabilizer for plastic materials,etc. It imparts good weather stability due to its very stable chemical nature. It provides good reactivity through its free functional epoxide groups when it is combined with resins containing carboxyl groups as saturated polyesters. The powder will cure with no especial of VOC. "HARDENER TP68 compatibility with resin isn't well for its high melting point, to avoid this default it’s necessary to distribute them or to make the curing temperature at a higher level.In case of epoxy\polyester hybrid powder coatings, the polyester should be low acidity. Before achieving the ideal gloss and multiple characteristics tests are needed."
