Potassium Carboxylate - VALIKAT K 1509 LR

Potassium Carboxylate - VALIKAT K 1509 LR

2-EHA-Free Potassium Catalyst with 15% Metal Content

VALIKAT K 1509 LR is a mix of potassium carboxylates, with 15% K content, diluted in 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. VALIKAT K 1509 LR was developed to provide an alternative to 2-ethylhexanoate-based potassium catalysts.
