Basic Information
- Brand Model: BYK - W966
- Product Name: Dispersant
- Packaging Specifications: 25 kg/blue iron drum, 165 kg/blue iron drum
- Chemical Composition: Salt solution of unsaturated polyamine amide and acidic polyester
Product Features
- Effective Viscosity Reduction: In filling systems such as unsaturated polyester resins, acrylics, polyurethanes, and epoxy resins, BYK - W966 can significantly reduce the viscosity of the system. This is because the structure of the salt solution of unsaturated polyamine amide and acidic polyester can weaken the interaction between fillers and resins, reduce internal friction, make the mixed system smoother, and facilitate subsequent processing operations such as spray molding and hand - lay - up molding.
- Excellent Anti - Settling Performance: It can effectively prevent fillers from settling during storage and processing. It forms a stable adsorption layer on the surface of filler particles, increasing the steric hindrance and electrostatic repulsion between filler particles, so that the fillers are uniformly dispersed in the resin, maintaining the stability of the system and avoiding quality problems caused by filler precipitation.
- Improve Filler Dispersibility: It has a good dispersing effect on common fillers such as calcium carbonate and aluminum hydroxide. It can make the filler particles distribute more uniformly in the resin matrix, give full play to the reinforcing and toughening effects of the fillers, and improve the mechanical and physical properties of composite materials, such as increasing the strength, hardness and wear resistance of products.
- Increase Filling Amount: With its viscosity reduction and dispersion characteristics, the amount of filler added in the filled resin can be increased without affecting the processing performance of the system, helping enterprises reduce production costs, and at the same time meeting the special requirements of products for certain properties (such as hardness, fire resistance, etc.).
Application Fields
- Fiber - Reinforced Composite Materials Field: In the production of fiber - reinforced spray and hand - lay - up resins, it helps reduce the viscosity of the resin, makes the resin better infiltrate the fibers, improves the bonding force between fibers and resins, and enhances the quality and performance of composite products. It is commonly used in the manufacture of composite materials in fields such as ships, auto parts, and aerospace.
- Adhesives Field: Applied in adhesive formulations, it improves the dispersibility and stability of fillers in adhesives, enhances the bonding strength and aging resistance of adhesives, and is suitable for bonding various materials such as wood, metal, and plastic.
- Drill - Promoted Putty Field: In the drill - promoted putty formula, it reduces the viscosity of the putty, making it easier to apply, and at the same time ensures the uniform distribution of fillers in the putty, improves the filling and repairing effect of the putty, and is often used in scenarios such as building decoration and mechanical repair.
Recommended Dosage
The specific dosage of BYK - W966 dispersant (based on the percentage of fillers in the system in the purchased form) needs to be adjusted according to different resin systems, filler types and formula designs. It is generally recommended to determine the optimal dosage through small - scale tests. During the test, observe indicators such as the viscosity change of the system, the dispersion state of the filler, and the anti - settling effect to achieve the best viscosity reduction, anti - settling and dispersion effects while controlling costs.
Addition Method
In the production process of related products, it is recommended to add BYK - W966 dispersant to the resin system before adding fillers, stir evenly, and then gradually add fillers for sufficient dispersion and mixing operations, such as using high - speed mixers, grinders and other equipment to ensure that the dispersant can fully play its role and achieve uniform dispersion of fillers.
Storage Conditions
It should be stored in a cool, dry and well - ventilated warehouse, avoiding direct sunlight and high - temperature environments. The ideal storage temperature range is between 5 - 30°C. In a low - temperature environment, the product may have an increase in viscosity. Before use, it needs to be restored to room temperature and stirred thoroughly to ensure stable product performance and no impact on the use effect. At the same time, pay attention to sealed storage to prevent the product from getting damp or reacting with components in the air and affecting the quality.
