Zinc Catalyst, similar to VALIKAT Zn 1910,BiCAT Z | |||
CUCAT-D604 | Bubble-free catalyst. similar to K-KAT XK-604 | ||
Specific Catalyst | Higest activity and bubble-free, but contain lead element. | Iso + Polyether Systems | |
CUCAT-HAB | Eco-friendly and bubble-free | ||
Suitable for “TDI+PPG+MOCA” system and “MDI+PPG+BDO” system,Long pot life and fast post curing, not sensitie to moisture | |||
Suitable for “MDI+PTMG+BDO” stystem, Stable production process; Long pot life and fast post curing;Effectively reduce product shrinkage | |||
Suitable for “MDI+Polyester+BDO” system and “TDI+Polyester+MOCA/BDO” system. Long pot life and fast post curing. | Iso + Polyester Systems | ||
CUCAT-SW10A | Suitable for “MDI+Polyester+BDO/EG”. Eco-friendly, Suitable for medium to high temperature curing processes. especially recommended for polyurethane screen mesh of MDI polyester systems. | ||
Polishing Agent | Solve the sticking problem of polyurethane products (casters, rollers) during polishing, No influence on mechanical properties such as hardness and tensile strength of products. Make the end products easy to polish and the surface brighter, Used for AGV wheels, it can effectively reduce the stains on the driving track. | General Purpose | |
Anti-abrasion Agent | Greatly improve the abrasion resistance of polyurethane products, will slightly affect the transparency of end products. Suitable for material with powder fillers. | ||
CUBD-NML | Improve the abrasion resistance of polyurethane products, not affect the transparent of end products. Suitable for products with high requirement of transparency. | ||
Antistatic Agent | No side reaction, no impact on product strength, the dosage is small, the color is light, and the appearance of the product is not affected. CUCE-W is for polyether systems, CUCE-ASW is for polyester systems. | ||
Defoaming Agent | YRXP-02S | Non silicon, high-efficiency, good compatibility, transparency and has little effect on the transparency of products. | |
High efficiency silicon defoamer is widely used in nonaqueous solvent and solvent-free systems, filled and unfilled systems, with excellent foam inhibition effect, small dosage. | |||
Moisture Scavenger | It is used to remove trace moisture from polyurethane raw materials, eliminate chemical bubbles, and provide wear resistance of materials. | ||
Anti-yellowing Agent | For both polyester and polyether systems. Solve the yellowing and aging problems cuased by UV and oxidant, but biases towards UV resistance. | General Purpose | |
Solve the yellowing and aging problems cuased by UV and oxidant | Polyether System | ||
Antioxidant | UVK-CLO | Solve the yellowing and aging problems cuased by oxidant. It does not affect the appearance chromaticity of products. CLO is recommended for polyester systems, TE is recommended for polyether systems. | --- |
UVK-TE | |||
Anti-hydrolysis Agent | CUWR-AH01 | It can effectively inhibit and delay the chain breakage of ester bonds due to hydrolysis, and extend the service life of polyester PU products. | Polyester System |
Release Agent | Spray on the mold surface. Not affect the surface printing on end products. | General Purpose | |
CUBD-INR01A | Premixed in PU raw material, Not affect the surface printing on end products. |
