Product function

In waterproof coatings, dibutyltin dilaurate mainly acts as a polyurethane catalyst, and its specific functions are as follows:

Accelerate the curing reaction: dibutyltin dilaurate has high catalytic activity and selectivity for hydroxyland isocyanate, and can accelerate the reaction of hydroxyl and isocyanate groups in polyurethane waterproof coatings, thereby promoting the curing of the coating. For example, in two-component polyurethane waterproof coatings, it can speed up the reaction speed after the two components are mixed, so that the coating can form a continuous and dense coating film faster, and improve construction efficiency.Improve coating performance: Through catalytic reaction, dibutyltin dilaurate helps to form a uniform and stable polyurethane network structure, thereby improving the physical properties of the coating, such aswear resistance, chemical corrosion resistance and aging resistance. This is crucial for waterproof coatings, which can ensure that the coating maintains a good waterproof effect during long-term use.Optimize construction performance: dibutyltin dilaurate can adjust the application period of the coating, that is, while ensuring that the coating has sufficientconstruction time, it can also complete curing within an appropriate time. This helps construction personnel better control the construction process and avoid construction problems caused by the coating curing.
