Store in a cool, dry place with adequate ventilation. Keep away from incompatible materials, open flames, and high temperatures.Please consult the Safety Data Sheet of this product.


Silcolease® PC-191 is a release modifier designed to give incrementally higher levels of release when added to the easy release formulations. Silcolease® PC- 191 may be used at 0% through 100% of the polymer component with release values increasing proportionally as the level of Silcolease® PC-191 is increased in the formulation. Unlike traditional tight release additives which are based on vinyl functional siloxane resins, Silcolease® PC-191 is based on hydride functionality. As a result, Silcolease® PC-191 may offer greater efficiency in affecting release response than the vinyl functional counterparts.




• Incremental release response to incremental levels of Silcolease® PC-191

• Good cures at high speed production

• Excellent bath stability
