Description

Dibutyltin Dilaurate CAS NO 77-58-7 is a highly effective organotin compound widely recognized as a catalyst and stabilizer. Its primary value lies in accelerating polyurethane and silicone curing reactions while preventing degradation in PVC formulations. This versatile chemical is essential for manufacturers in the polymer, coatings, and sealants industries seeking to optimize production efficiency and product longevity.

Application

• Polyurethane Catalyst: A key catalyst for the production of flexible and rigid foams, elastomers, coatings, and adhesives.
• PVC Stabilizer: Acts as a heat stabilizer in polyvinyl chloride (PVC) processing to prevent thermal degradation during extrusion and molding.
• Silicone Cure Catalyst: Used to catalyze the cross-linking (curing) of room-temperature vulcanizing (RTV) silicone rubbers and sealants.
• Esterification & Transesterification Catalyst: Facilitates organic synthesis reactions for producing plasticizers, lubricants, and biodiesel.
• Adhesive & Sealant Formulations: Enhances the curing performance and final properties of industrial and construction-grade sealants.
• Paint & Coating Additive: Improves drying time and film formation in various coating systems.
