SILCOLEASE PC-31 may be stored for up to 6 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


Silcolease® PC-31, Silcolease® PC-50 and Silcolease® PC-868 are emulsions of methyl hydrogen polysiloxane crosslinkers for use with both platinum catalyzed addition cure and tin catalyzed condensation cure emulsion release coatings. The methyl hydrogen polysiloxane in Silcolease® PC-31 is a copolymer, while Silcolease® PC-868 is based on a methyl hydrogen polysiloxane homopolymer. Silcolease® PC-50 is a proprietary blend of two methyl hydrogen crosslinkers and is especially suited to work with troublesome substrates to provide superb anchorage of the cured silicone coating.

The homopolymer and copolymer crosslinkers provide the flexibility of creating a range of crosslink matrices from a dense, tightly knit matrix to one that is comparatively open. With troublesome adhesives or substrates, release and anchorage improvements may be realized by an interchange of crosslinkers.
