SILCOLEASE XL 91 A can be used as a crosslinker for the SILCOLEASE solvent-based systems (SILCOLEASE 7410, SILCOLEASE 7420 or SILCOLEASE 7440) in the proportion of 0.5 to 1.5 parts for 100 parts of the base polymer.
For a suitable bath preparation, it is recommended to mix the products in the following order: the solvent should be introduced first, then the base polymer, if necessary the RCA, the crosslinker SILCOLEASE XL 91 A and at the end the catalyst.

SILCOLEASE XL 91 A may be stored at temperatures between -20°C / -4°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.


SILCOLEASE XL 91 A is a silicone polymer used as a crosslinker of the SILCOLEASE polyaddition solvent-based systems, for example SILCOLEASE 7410, SILCOLEASE 7420 and SILCOLEASE 7440.
