Polyester resin R568 TPA is clear ISO-NPG, thixotroped, pre-accelerated resin with longer gel time.
Thixotropic resin formulated for laminating by contact or spray up. No drainage on inclined surface. Pre-accelerated resin which cures at ambient temperature with addition of MEKP. Good mechanical properties. Good chemical properties. Good hydrolysis resistance. R568 TPA is designed to bond to rigid PVC (uPVC). Provided that the surface is clean and grease-free GRP/uPVC mouldings have a good adhesion. Nevertheless abrasion of the uPVC surface will improve the adhesion. Food contact applications: according to the global migration test
