Butylstannonic acid

Butylstannonic acid (CAS 2273-43-0 ), also referred to as butylstannoic acid, is an organotin compound used industrially as a catalyst and catalyst precursor in polymer curing and cross-linking systems. Its reactivity with hydroxyl and carboxyl functional groups makes it a practical choice for controlled condensation reactions across several manufacturing sectors. In plastics and polymer processing, it functions as a catalyst. It is used for the production of polyesters, polyurethanes, and silicone systems where controlled cure rates are required. The construction sector uses it in formulating sealants and coatings that depend on tin-catalyzed cross-linking. These applications provide durable adhesion and weather resistance. Textile and leather finishing operations employ it as a precursor in mordanting and surface treatment processes where organotin chemistry improves substrate bonding. In paper manufacturing, it supports the development of specialty coatings requiring precise cross-link density. This chemical is supplied as a white to off-white powder and is available in technical grade for industrial use. Purity levels are typically specified by tin content, which is the primary quality parameter buyers use to assess batch consistency. Packaging is offered in multi-kilogram quantities suited to industrial procurement volumes. Contact us for supply of Butylstannonic acid Request Quote
