Polyteks’ Poly-Optic 14 Part X Accelerator speeds the cure of Poly-Optic products (recommended for castings less than 1/2″ thick). Experiment to determine how much Part X is needed for your application. Do not exceed 1% of the total mixed weight as final physical properties may be affected. Example: 0.5 grams of Part X in a 100 gram mix of Poly-Optic 1410 Clear Casting Resin cuts the pour and cure times in half.
