SILCOLEASE XL 327 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 327 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 327 will remain permanently, this is normal and to be expected.


Typical Formulation:
SILCOLEASE Base Vinyl Polymer Product : 100 parts
SILCOLEASE XL 327 : 3 to 12 parts
SILCOLEASE CATA 12070 : 1.5 to 3 parts

SILCOLEASE XL 327 has been specifically designed to produce a strong anchorage on a wide variety of substrates. On some papers a longer period of time is required for full anchorage to develop. As the cure of the silicone coating is unaffected by this anchorage phenomenon, stable release values of adhesive in-line coating laminates can be achieved.
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.

SILCOLEASE XL 327 may be stored at a temperature between 2 °C/ 36 °F and 30 °C/ 86 °F for up to 18 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.Heavy Metals;RoHS;WEEE
