Clear silicone comes as a kit of 1gallon (9 lb) silicone A and 1 pt (.9lb) curing agent B.
This silicone cures at room temperature with no shrinkage and offers a unique water clear see through rubber with excellent tear strength, chemical and heat resistance.
Curing: allow the mold to cure overnight (at least 16 hours) at room temperature (77°F/25°C) before demolding. Do not cure rubber where temperature is less than 65°F/18°C. Post Curing the mold will aid in quickly attaining maximum physical and performance properties. After curing at room temperature, expose the rubber to 80°C for 2 hours and 100°C for 2 hours. Allow mold to cool to room temperature before using
NOTE: This clear silicone will cause rubber to yellow when applying post curing.
