Potassium Octoate - VALIREX K 10 DEG

Potassium Catalyst with 10% Metal Content

VALIREX K 10 DEG is a potassium-based metal carboxylate with 10% 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.
