Potassium Octoate - VALIREX K 15 DEG

Potassium Catalyst with 15% Metal Content, Standard Grade

VALIREX K 15 DEG is our standard grade potassium-based metal carboxylate with 15% K, diluted in diethylene glycol. 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.
