Polymer of 2,2-[alkylimino]bisethanol with bis-isocyanate

[Structural formula]

[Specification]

[Performance]
This product is a high molecular weight substance with certain viscosity, synthesized through polycondensation reaction using diisocyanate and alkyliminodiethanol as raw materials. It is essentially a low molecular weight polyurethane (spandex) product. Compared to conventional anti-yellowing agents, it offers the following characteristics: 1. Excellent compatibility with spandex fibers. 2. Superior inhibition of discoloration (e.g., caused by light exposure and smoke fume exposure) and prevention of yellowing in spandex fibers. 3. Outstanding resistance to chlorine-containing rinse agents during washing of spandex fibers. 4. Significant improvement in the dyeing properties of spandex fibers and notable inhibition of fading in dyed spandex fibers. 5. A multifunctional additive for spandex fibers, providing composite functions of multiple additives, especially excellent high-temperature resistance, making it particularly suitable for large-scale continuous production processes of spandex fibers.

[Application]
This product is used in the polyurethane industry, such as an anti-yellowing agent for spandex fibers, synthetic leather, artificial leather, etc.
[Safety]
Avoid contact with moisture and air during storage and transportation. Use nitrogen protection during application. Store in a dark place away from light.
[Packaging and Storage]
This product is packaged in plastic drums, with a net weight of 200kg per drum.

[Use]
This product is applied to polyurethane industry. For example, it can be used as yellow inhibitor of fiber, synthesized leather, man-made leather.

[Safety]
In the process of storage and transportation, avoid contact with water, sunshine and air. In the using process use nitrogen protect.

[Packing and storing]
