Electron Microscopy Sciences Clear Silicone Rubber Kit

Electron Microscopy Sciences 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. Allow the mold to cure overnight (at least 16 hours) at room temperature (77 degree f/25 degree c) before demolding. Do not cure rubber where temperature is less than 65 degree f/18 degree 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 degree c for 2 hours and 100 degree 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. Clear silicone comes as a kit of 1 gallon (9 lb) silicone a and 1 pint (.9lb) curing agent b. - EMS (Additional S&H or Hazmat Fees May Apply)
