SILCOLEASE XL 325 is used as a crosslinker for the bath preparation of SILCOLEASE solventless systems in the proportion of 3 to 12 parts for 100 parts of polymer, and at a Platinum catalyst concentration between 25 and 50 ppm. It is always used with an appropriate polymer and catalyst from the SILCOLEASE range of products.
With some SILCOLEASE vinyl polymers, the addition of SILCOLEASE XL 325 to the coating bath will produce a cloudy formulation. Whilst we recommend very thorough mixing as with all our solventless formulations, the hazy appearance of some baths using SILCOLEASE XL 325 will remain permanently, this is normal and to be expected.
Typical Formulation:
SILCOLEASE Base Vinyl Polymer Product100 parts
SILCOLEASE XL 3253 to 12 parts
SILCOLEASE CATA 120701.5 to 3 parts
Warning: SILCOLEASE CROSSLINKER and SILCOLEASE CATALYST may react violently together and therefore must not be blended together separately from the other components of the system.

Avoid discharge into drains, water courses or onto the ground. Store in original tightly closed container. equipped with a degassing device. 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.Heavy Metals
