It is used, among other things, as a catalyst in various polyurethane-based plastics, especially for hard foams and molded foams. As a water-insoluble additive, it is technically well suited for water-driven systems. A wide range of products is used in systems of this type, from wear-resistant seats on trains or for motorcycles, to office chairs and foam paint rollers.
Another possible application is as a stabilizer for plastics, which increases the weather resistance of the final product and thus enables longer life cycles. In addition, dibutyltin bis (2-ethylhexyl mercaptoacetate) is an intermediate in the chemical industry and is processed in a number of processes.
Storage
In handling, adequate suction should be ensured on the processing machines. The containers must be stored cool and dry in a well-ventilated place and should be tightly sealed. The formation of aerosols should be avoided.
