TP 105 is an alkylamine crosslinker with –OH functionality capable to crosslink carboxyl functional polyester for highly exterior durable powder coatings applications. ORIENTATIVE FORMULATION (PES/TP105 95:5) (parts by weight) Polyester resin 56,0 TP 105 3,0 Kronos 2310 (TiO2) 40,0 Thixatrol ST 0,8 Benzoin 0,2 Gel time: 200ºC – 90” Curing requirement:200℃ 8 minutes POLYESTER type (From China): Appearance: pale yellow flake Acid number: 30±5mgKOH/g Viscosity at 175ºC 3,5---6,0 Pa·S Softening point: 95----110℃ Glass transition(DSC): >50℃ Basic properties of coating film(film thickness 60μm) Impact(direct.reverse) 50Kg·cm Pencil hardness H Bending(ф2mm) pass Gloss(60°) >90% QUVB313 240 ≥75% Application: Mainly used as Curing Agent for polyester powder coating. It imparts good weather stability due to its very stable chemical nature. It provides good reactivity through its free functional hydroxyl groups when it is combined with resins containing carboxyl groups as saturated polyesters. The powder will cure with no emision of VOC. Packing: In bags of 20kgs net each with plastic lining. Claim: above information is offered as a recommendation only
