Hegrecat MC112 (Dibutyltin Dilaurate)  CAS: 77-58-7


Appearance: MC112 usually appears as a pale yellow, viscous liquid

Key Properties:

MC112 is used to promote urethane(polyol-isocyanate) reaction or gel reaction in the preparation of flexible and rigid polyurethane foams, coatings, adhesives, sealants and elastomers.

It significantly accelerates the formation of urethane linkages, which are fundamental for constructing the polyurethane polymer network. Its catalytic activity is well - balanced, offering a reaction rate that allows manufacturers sufficient time to process materials during production while still ensuring timely curing. This catalyst also plays a key role in promoting cross - linking within the polyurethane structure. By enhancing cross - linking, MC112 can improve mechanical properties such as tensile strength, tear resistance, and hardness of the final polyurethane products. In foam production, MC112 is crucial for controlling the cell - formation process. It helps in creating a uniform cell structure, which is essential for determining the quality of foam products. A uniform cell structure can enhance the insulation efficiency of rigid foams and the comfort level of flexible foams.

Applications

Flexible Polyurethane Foams:MC112 is extensively used in manufacturing flexible polyurethane foams. In the production of foams for furniture upholstery and automotive seating, it contributes to the formation of a more uniform cell structure. This not only enhances the foam's resilience but also enables it to better withstand repeated use and maintain its shape over time, providing enhanced comfort for users. For example, in the production of low - density flexible foams, MC112, in combination with other catalysts and additives, helps achieve the desired balance between density, strength, and flexibility.​

 

Rigid Polyurethane Foams:In the production of rigid polyurethane foams for insulation purposes, MC112 is widely applied. It promotes the creation of a closed - cell structure. These closed - cell rigid foams, which are used in building insulation panels, refrigerators, and industrial cold storage facilities, benefit from MC112 - catalyzed reactions. The foams have low thermal conductivity, high compressive strength, and good dimensional stability. They are thus ideal for maintaining temperature and structural integrity in various applications, reducing energy consumption in buildings and ensuring the preservation of goods in cold storage.​

 

Polyurethane Coatings and Adhesives:For polyurethane coatings, MC112 accelerates the curing process, significantly reducing the drying time and improving production efficiency. In adhesives, it promotes strong bonding between different substrates, whether they are metals, plastics, or woods. MC112 - catalyzed adhesives offer reliable and durable joints. Additionally, it can enhance the chemical resistance of coatings and adhesives, making them more suitable for use in harsh environments.​

 

Elastomers and Sealants:MC112 is also used in the production of polyurethane elastomers and sealants. In elastomers, it helps in achieving the right degree of cross - linking, resulting in materials with excellent abrasion resistance, high tensile strength, and good flexibility. These properties make them suitable for applications such as wheels, rollers, seals, and gaskets. In sealants, MC112 ensures proper curing and adhesion, providing effective sealing performance in various applications, including construction and automotive industries.​

 

Our MC112 product is manufactured under strict quality control, ensuring high purity and consistent performance. It is a reliable choice for polyurethane manufacturers aiming to produce high - quality products with enhanced performance characteristics.
