Category | Model | Application and Function |
Catalysts for two-part systems | Eco-friendly, anti-hydrolysis, bubble-free, suitable for “Iso + polyester / castor oil” formula systems. | |
Bubble-free, contains eco-friendly tin element, suitable for “Iso + polyester / castor oil” formula systems. | ||
Eco-friendly and bubble-free Catalysts, suitable for “Iso+ polyether polyol” formula systems. | ||
General-purposed, eco-friendly, anti-hydrolysis, bubble-free | ||
General-purposed, bubble-free, high activity, but contains lead element. | ||
Catalyst for one-part systems （Moisture-cured systems） | High catalytic activity, good material storage stability, reduced surface bubbles. | |
Tin-free eco-friendly Catalyst, maintains good catalytic effect at low temperature. | ||
High activity, the addition amount is half of T12, maintain good catalytic effect at low temperature. Suitable for aliphatic one-part systems. | ||
The activity is more than 10 times higher than that of T12, suitable for MS sealant (a siloxane terminal sealant). | ||
Dispersant | It can significantly reduce the viscosity of the solvent-free formula containing fillers., improve the levelness, reduce scratches, and prevent the aggregation and hardening of powder fillers; | |
Rheological Agent | A small amount of 0.1-0.2% can effectively solve the powder sedimentation and improve leveling. Increase the addition amount to 0.6-2%, it can quickly form thixotropy and can be used for anti sagging coating on vertical or slope surface. | |
Defoaming Agent | Non-silicon defoamer, excellent foam inhibition and foam breaking effects, good compatibility with polyurethane system, and little influence on transparent system. | |
Organosilicon defoamer, generally used in non-aqueous solvent and solvent-free systems, with excellent foam inhibition and foam breaking effects, low dosage. | ||
Moisture Scavenger | It is used for water removal of non-isocyanate components in polyurethane raw materials, such as polyols, solvents, plasticizers and small molecular chain extenders. It can eliminate the influence of trace moisture in raw materials and effectively reduce the bubble, bulging, hollowing, pinhole and other phenomena caused by the reaction of trace moisture and isocyanate to generate CO2. | |
Anti-aging Agent | Reduce the damage caused by external factors such as light, oxygen and heat to the molecular structure of polyurethane, delay the yellowing and aging of polyurethane. Only a small amount of addition can significantly improve the problems such as surface pulverization and discoloration of polyurethane flooring materials. | |
Antioxidant | Additives that inhibit the thermal oxygen aging of polyurethane prepolymers, composites, products, etc., especially can prevent and delay the occurrence of discoloration, aging and degradation under high temperature. Recommended for applications such as preventing discoloration during prepolymer synthesis. | |
Antistatic Agent | High-efficiency antistatic agent with good compatibility, Not affect the material properties; The addition amount is small,while the long-term anti-static property is durable. CUCE-W is recommended for Polyether system, CUCE-ASW is for polyester system. |
