Hegrecat MC109 (stannous octoate) CAS: 301-10-0

Appearance: Colorless to pale yellow liquid

Key Properties:

MC109 catalyst is a strong, metal-based urethane (polyol-isocyanate) catalyst that is primarily used in flexible slabstock polyurethane foams.

MC109 is a powerful accelerator for the reaction between isocyanates and polyols. It effectively promotes the formation of urethane linkages, which are fundamental for constructing the polyurethane polymer network. The catalytic activity of MC109 is well - balanced, offering a reaction rate that gives manufacturers sufficient time to process materials during production while still ensuring timely curing. This catalyst also plays a key role in influencing the cross - linking density of the resulting polyurethane. By modulating the cross - linking, MC109 can enhance mechanical properties such as tensile strength and tear resistance. In foam production, it is crucial for controlling the foam - forming process, helping to create a uniform cell structure. This uniform structure is essential for determining the quality of foam products, affecting aspects like the insulation efficiency of rigid foams and the comfort level of flexible foams.

Applications

Flexible Polyurethane Foams:MC109 is extensively used in the production of flexible polyurethane foams. In the manufacturing of furniture upholstery and automotive seating foams, it contributes to the formation of a more uniform cell structure. This not only enhances the foam's resilience but also allows 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, MC109, 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, MC109 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 MC109 - 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, MC109 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. MC109 - 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.

Other Polymer Applications:Beyond polyurethane, MC109 can also be used as a catalyst in the production of polylactic acid and as an intermediate in various chemical reactions. In the context of urethane foams, lubricants, addition agents, and stabilizers for transformer oils, MC109's catalytic properties play an important role in facilitating reactions and improving product performance.

Our MC109 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.
