Cotin™ Tin Catalyst Series

The Cotin™ Catalyst Series provides variable cure rates for urethane and silicone reactions in foam and elastomeric applications.

They can be used in primary reactions such as the polyol-isocyanate and water-isocyanate reactions, as well as the secondary types such as allophanate and biuret formation.

Applications

Excellent general purpose catalyst for any polyol-isocyanate reactions. 

Applications for the Cotin™ Tin Catalyst Series include room temperature & moderate to rapid catalysis for RTV (Room Temperature Vulcanization) Silicones.

Cotin™ catalyzed RTV silicones begin to cure immediately upon being exposure to air. They work effectively as a sealants that are water-resistant, adhesive, and hold their shape. They are most commonly used in wet environments such as building, bathroom, and kitchen sealants.

The Cotin™ Catalyst Series applications include room temperature & moderate to rapid catalysis for elastomers. RTV Silicone Gasket is a single component vulcanizing elastomeric gasket for mechanical parts providing tough & flexible seal.

Cotin™ 200 is a liquid organotin catalyst recommended for the manufacture of silicone and polyurethane systems. Cotin™ 200 is a “moderate” urethane catalyst, not yielding rapid or slow cures. It can be used in primary reactions such as the polyol-isocyanate and water-isocyanate reactions, as well as the secondary types such as allophanate and biuret formation.

Cotin™ 227 is a liquid organotin catalyst recommended for use in room temperature vulcanized (RTV) silicone systems and polyurethane foams and elastomers. Cotin™ 227 is a “moderate to rapid” catalyst for relatively fast cures. It can be used in primary reactions such as the polyol-isocyanate and water-isocyanate reactions as well as the secondary types such as allophanate and biuret formulation.

Cotin™ 280 is a liquid organotin carboxylate catalyst recommended for use in room temperature vulcanized (RTV) silicone systems and polyurethane foams and elastomers. Cotin™ 280 is considered a “moderate to rapid” catalyst, for relatively faster cure.

Cotin™ 430 is a liquid organotin catalyst recommended for the manufacture of silicone and polyurethane systems. It offers less moisture sensitivity in comparison to conventional organotin catalysts. Cotin™ 430 is considered a “slow” catalyst and is used in silicone reactions and urethane formulations where slow catalysis is required.
