Your trusted performer

Electrocoat manufacturers trust FASCAT catalysts for the most exacting specifications for automotive and industrial resin and paste applications.

Your cost-effective solution

Ester manufacturers recognize FASCAT catalysts as superior to caustics and titanates due to overall lower manufacturing costs. Most applications require extremely low loading levels to achieve desired reaction rates.

FASCAT® catalysts can reduce costs compared to titanates:

  • Reduce capital costs of equipment needed to control for hydrolytic instability of titanates
  • Can be charged up front with other raw materials
  • Can be used at lower temperatures

Your regulatory partner

FASCAT 2000 and 4100 series products are very high purity - offering manufacturers seeking to minimize dibutyltin (DBT) and tributyltin (TBT) confidence when it comes to meeting stringent regulatory standards.
