Black science and technology of the incoming | polyurethane adhesives stability good partner

2022/08/18

In recent years, with the country's increasing attention to volatile organic compounds emissions, waterborne coatings, adhesives, leather finishing and other technologies have been rapidly developed. Therefore, the customer's quality requirements for polyurethane products are more and more strict, but also promote the constant upgrading of the stabilizer industry.

Polyurethane, as a reaction product of polyols (polyhydroxyl) and multifunctional isocyanates, offers a variety of options for the creation of adhesives and sealing systems. Its excellent versatility makes it suitable for products ranging from very soft and malleable products to high resilience products, and even for structural construction products.

Polyurethane adhesive is a kind of middle and high grade adhesive with excellent flexibility, impact resistance, chemical resistance and wear resistance. Because of this series of advantages, polyurethane adhesives are widely used in carpentry, shoe making, packaging, and automotive industries.

The factors affecting the stability of polyurethane are more complex, such as thermal oxygen, light, nitrogen oxygen compounds and so on. Therefore, how to solve the aging yellowing problem of polyurethane products is always committed to the research topic of Songyuan.

CS B5075 SONGSORB ®

To maintain application performance and ensure long-term durability, stabilizers are key elements of polyurethane adhesive and sealant systems. Songwara's SONGSORB®CS B5075, delivered in a liquid mixture, integrates several key functions:

✓Contains an antioxidant that prevents the autooxidation cycle during processing and end use

✓Contains a wide wavelength UV absorber that diverts the UV radiation energy as harmless heat energy

✓Contains a blocked amine photostabilizer (HALS) for the decomposition of reactive degradable substances

SONGSORB®CS B5075 is easy to operate and fully miscible with common polyol components of aromatic and aliphatic polyurethane systems. A typical SONGSORB®CS B5075 dosage is 0.5-3.0% depending on the application scenario and end-use requirements.
