BLUESIL PT ACC can be mixed either into the Part A prior to mixing with the Part B, or directly into the mixed Part A and Part B. Proper de-airing of the mixed silicone is essential to produce the best possible molds.

BLUESIL PT ACC may be stored for up to 12 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


BLUESIL PT ACC is an accelerator for platinum cure, polyaddition silicone moldmaking compounds. It can be used with many of Elkem Silicones addition cure products to customize the de-mold time to as short as 2 hours, allowing multiple molds to be made each day per master. This can be done without adversely affecting the physical properties of the elastomer.
