SILCOLEASE CATALYST 91B is used as a catalyst for the SILCOLEASE 7410 SERIES system in the proportion of 0.8 to 1.4 parts for 100 parts of SILCOLEASE 7410 SERIES.


SILCOLEASE CATA 91 B 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 CATALYST 91B is a platinum complex diluted in a solvent. It is the catalyst used for the solvent based SILCOLEASE systems intended for release coating of paper, film and various substrates: SILCOLEASE 7410 SERIES. SILCOLEASE CATALYST 91B is used in polyaddition reaction only. The release properties of the coating can be modified.

Polyaddition Catalyst

Silcolease Catalyst 91B is a catalyst specifically designed to have low addition level, relatively lower cost while providing high performance to the SILCOLEASE 7410 SERIES systems. Compared to another catalyst for these systems, Silcolease catalyst 90B, this catalyst performs similar to or even better than 5p 90B in curing, bath stability, release performance.
