SILCOLEASE CATA 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 91 A: 1 part

SILCOLEASE CATA 90 B: 4 parts

Dilution solvent: to solids level required

Bath 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 91 A, mix thoroughly before finally adding

SILCOLEASE CATA 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 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.Food Contact;Heavy Metals

SILCOLEASE CATA 90 B

SILCOLEASE CATA 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 CATA 90 B is used solely in polyaddition reaction systems.
