Application of dimethyltin dilaurate in polyurethane catalyst

admin 6月 27th, 2024 News

Dibutyltin dilaurate (DBTL or DBL for short) is widely used in polyurethane catalysts and is a polyurethane (PU) catalyst. One of the important auxiliary materials in production. Its main functions and application features are as follows:

Efficient catalysis: As a gel catalyst in polyurethane synthesis, dimethyltin dilaurate can significantly accelerate the reaction between isocyanate and polyol, especially the reaction between hydroxyl groups and isocyanate groups. The addition reaction promotes the formation of prepolymer and the expansion of polymer chains, thereby improving production efficiency, shortening curing time, and achieving rapid prototyping.
Enhance performance: Its use helps to improve the physical and mechanical properties of polyurethane products, such as enhancing hardness and improving durability. properties and adhesion, making the coating more uniform and smooth, improving the overall quality and service life of the product.
Improve processing properties: In the manufacturing process of polyurethane foams, coatings, adhesives and sealants, dimethyltin dilaurate can regulate foaming rate and gel time, helping Control the foam structure, reduce bubbles, make the internal structure of the product more uniform, and improve the controllability of the production process.
Used in conjunction with other catalysts: In some formulations, dimethyltin dilaurate is often used in combination with amine catalysts to achieve catalytic effects and foam density control, especially when required In applications such as high-speed production of high-density structural foam, spray rigid foam and rigid foam board.
Wide range of application: It is not only suitable for the production of soft foam, hard foam, and semi-rigid foam, but also widely used in the field of CASE (coatings, adhesives, sealants, elastomers) , and in the RIM (reaction injection molding) process, showing good applicability and flexibility.
Environmental considerations: Although dimethyltin dilaurate is effective as a catalyst, the environmental and health risks of organotin compounds have prompted the industry to explore more environmentally friendly alternatives in recent years. to comply with increasingly stringent environmental regulations.

In summary, the application of dimethyltin dilaurate in polyurethane catalysts highlights its role in improving production efficiency, optimizing product performance and The value of adapting to different processing needs, but at the same time, it is necessary to pay attention to its sustainability and environmental protection issues to adapt to future industry development trends.
