SILCOLEASE CATALYST 90 B is used as a catalyst for the SILCOLEASE solvent based systems (SILCOLEASE 7420 or 7410) in the proportion of 4-6 parts for 100 parts of the base polymer.
Recommended formulation, typical:
SILCOLEASE 7420: 100 parts
SILCOLEASE CROSSLINKER: 1 part
SILCOLEASE CATALYST 90 B: 4 parts
Dilution solvent: to solids level required
preparation:
The solvent used for diluting can be aliphatic or aromatic.
It is recommended to charge solvent first and commence stirring.
It is recommended to mix the products while stirring in the following order:
Disperse the polymer SILCOLEASE 7420 completely in the dilution solvent, then add SILCOLEASE RCA 3 when needed, mix these together thoroughly and then add SILCOLEASE CROSSLINKER , mix thoroughly before finally adding SILCOLEASE CATALYST 90 B and completing mixing to a fully homogeneous blend.
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 CATA 90 B A1 may be stored at a temperature 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 CATA 90 B A1

SILCOLEASE CATALYST 90 B is a platinum complex diluted in a solvent. It is the catalyst used for the solvent based SILCOLEASE systems, such as SILCOLEASE 7420 and 7410, intended for RELEASE COATING of paper, films and various substrates. SILCOLEASE CATALYST 90 B is used solely in polyaddition reaction systems.
