Hegrecat LA131 (Tetramethylhexamethylenediamine) CAS: 111-18-2

Appearance: Colorless to pale yellow liquid

Key Properties:

LA131's structure, featuring tertiary amine groups, enables it to effectively accelerate the reaction between isocyanates and polyols in polyurethane synthesis. It has a balanced catalytic activity, promoting the formation of urethane linkages. In addition, LA131 can influence the cross - linking density of the resulting polyurethane network. This leads to the enhancement of mechanical properties such as tensile strength and tear resistance. It also helps in controlling the foam - forming process in polyurethane foam production, ensuring the formation of a more uniform cell structure, which is crucial for the quality of foam products.

Applications

Rigid Polyurethane Foams: In the production of rigid polyurethane foams for insulation applications, LA131 plays a significant role. It promotes the reaction that leads to the creation of a closed - cell structure. These closed - cell rigid foams are widely used in building insulation panels, refrigerators, and industrial cold storage facilities. The use of LA131 ensures that the foam has low thermal conductivity, high compressive strength, and good dimensional stability, making it an ideal choice for maintaining temperature and structural integrity in various applications.

Flexible Polyurethane Foams: LA131 can also be applied in the production of flexible polyurethane foams. It contributes to the formation of a more uniform cell structure, enhancing the foam's resilience. This makes it suitable for applications in furniture upholstery and automotive seating, where comfort and durability are essential. The foam produced with LA131 can better withstand repeated use and maintain its shape over time.

Polyurethane Elastomers:In the synthesis of polyurethane elastomers, which are used in applications such as wheels, rollers, seals, and gaskets, LA131 promotes rapid curing and high cross - linking density. This results in elastomers with excellent abrasion resistance, high tensile strength, and good flexibility, enabling them to perform well in demanding mechanical applications.

Polyurethane Coatings and Adhesives: For polyurethane coatings and adhesives, LA131 accelerates the curing process. This not only reduces the production time but also improves the adhesion strength of the adhesives to various substrates. In coatings, it helps in achieving a smooth and durable finish, enhancing the chemical resistance of the coated surface. Whether it's protecting metal surfaces from corrosion or bonding different materials together, LA131 - catalyzed coatings and adhesives offer reliable performance.

Our LA131 product is manufactured with strict quality control measures to ensure high purity and consistent performance. It is a reliable choice for polyurethane manufacturers aiming to optimize their production processes and produce high - quality products that meet the diverse needs of different industries.
