Dibutyltin Dilaurate CAS 77-58-7

Introduction

Dibutyltin dilaurate (DBTDL) is an organic tin additive that is insoluble in water but soluble in organic solvents such as toluene, chloroform, and petroleum ether. It appears as a colorless or light yellow oily liquid at room temperature and as white crystals at low temperatures. In practical applications, DBTDL can endow products with excellent thermal stability, transparency, weather resistance, and compatibility. Compared with sulfur-containing organic tin, DBTDL does not have the same smell and cross-contamination problems as sulfur-containing compounds; compared with other organic tin, DBTDL has the best lubricity. In addition, in many other scientific research and industrial fields, DBTDL is also often used as a drying agent, catalyst, etc. Due to its excellent and unique performance, DBTDL occupies a place among organic tin additives.

Product Specifications

Application 

1. Used as a heat stabilizer for polyvinyl chloride, a curing agent for silicone rubber, a catalyst for polyurethane foam, etc.
2. Used as a plastic stabilizer and a rubber curing agent
3. It can be used as a heat stabilizer for polyvinyl chloride. It is the earliest type used in organotin stabilizers. It has excellent lubricity, weather resistance and transparency. It has good compatibility with plasticizers, does not spray frost, has no sulfide pollution, and has no adverse effects on heat sealing and printing properties. Because it is a liquid at room temperature, its dispersibility in plastics is better than that of solid stabilizers. This product is mainly used for soft transparent products or semi-soft products, and the general dosage is 1-2%. It has a synergistic effect when used in combination with metals or epoxy compounds such as cadmium stearate and barium stearate. In hard products, this product can be used as a lubricant and used in combination with maleic acid organotin or thiol organotin to improve the fluidity of resin materials.
