Potassium Octoate - VALIREX K 15 DEG 30

Potassium Octoate - VALIREX K 15 DEG 30

Potassium Catalyst with 14-15% Metal Content, Low-Viscosity

VALIREX K 15 DEG 30 is a potassium-based metal carboxylate with 14-15% K, diluted in diethylene glycol, and with slightly lower viscosity than our standard product VALIREX K 15 DEG. The product is used as co-catalyst to boost cobalt performance and reduce color in unsaturated polyester resins and gelcoats. Further, the product is also used as liquid trimerization catalyst for polyisocyanurate (PIR) foam. Our catalyst ensures a highly cross-linked polyisocyanurate foam structure, resulting in strong and durable insulation products.
