Product Name | Model | Property | Application |
PU Catalyst | Reduce the trouble of scraping caused by casting leakage; Reduce scrap rate and improve production efficiency; Can be mixed with prepolymer in advance | Prepolymer method, Curing temperature at 100-120C, MOCA system. | |
It is insensitive to water and targets the reaction of isocyanate with hydroxyl. It has high catalytic efficiency for 2 components polyurethane system materials using MOCA, BDO and other amines and alcohols as chain extenders.The formula design is more flexible, and the mechanical properties of the final product are improved. | Semi prepolymer method, Curing temperature at 80-90C | ||
Suitable for MDI+PTMG+BDO stystem, Stable production process; Long pot life and fast post curing;Effectively reduce product shrinkage | |||
Suitable for MDI+Polyether+BDO system and TDI+Polyester+MOCA（or BDO）system. Long pot life and fast post curing. | |||
Suitable for TDI+PPG+MOCA system and MDI+PPG+BDO system,Long pot life and fast post curing, not sensitie to moisture | |||
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, Does not affect the high and low temperature resistance of products, The product is easy to polish and the surface is brighter, Used for AGV wheels, it can effectively reduce the stains formed by tracks. | General Purpose | |
Anti-abrasion Agent | Greatly improve the abrasion resistance of polyurethane products | General Purpose | |
Antistatic Agent | No bubbling, no side reaction, no hardness reduction, no impact on product strength, the addition amount is small, the color is light, and the appearance of the product is not affected. CUCE-ASW is especially suitable for polyester polyol system with good compatibility and high transparency | General Purpose | |
Defoamer | Non silicon, high-efficiency, good compatibility, transparency and has little effect on the transparency of products. | General Purpose | |
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. | General Purpose | ||
Moisture Scavenger | It is used to remove trace moisture from polyurethane raw materials, eliminate chemical bubbles, and provide wear resistance of materials. | General Purpose | |
Anti-yellowing Antioxidant | Good compatibility, migration resistance, less efficient addition; Light color does not affect the appearance chromaticity of products. | Polyether system | |
Solve the problem of different yellow spots of products after carton packaging. | |||
Good compatibility, migration resistance, less efficient addition; Light color does not affect the appearance chromaticity of products. | Polyester system | ||
Release Agent | Solve the problem that the product cannot be printed or painted. | General Purpose | |
PU Adhesive | For bonding CPU to various polar surfaces such as metals, excellent adhesion performance for aluminum, anti high temperature and with high shear resistance; | General Purpose | |
Two-component adhesive, for bonding CPU and TPU to various polar surfaces including stainless steel. anti high temperature and with high shear resistance; | |||
For the bonding of TPU, PU foam / sealant to nylon surface. |
