Product Details
- Brand Model: BYK - 220S
- Product Name: Dispersant
- Packaging Specification: 25 kg/blue iron drum
- Chemical Composition: Low - molecular - weight unsaturated acidic polycarboxylic acid polyester solution containing polysiloxane copolymer
Product Features
- Performance advantages brought by unique chemical structure: Polysiloxane copolymer has good surface activity, which can reduce the surface tension of the system, making pigment particles easier to be wetted and dispersed. Low - molecular - weight unsaturated acidic polycarboxylic acid polyester can interact with the surface of pigments. Through electrostatic repulsion and steric hindrance effect, it can effectively prevent the flocculation and agglomeration of pigment particles and keep the pigment in a uniformly dispersed state in the system.
- Wide system adaptability: It is suitable for various coating systems, such as solvent - based coatings and water - based coatings. In solvent - based coatings, it can be well compatible with various organic solvents and resins to help pigment dispersion; in water - based coating systems, it can also overcome problems such as high surface tension of water by virtue of its special structure to achieve stable dispersion of pigments.
- Improve the comprehensive performance of coatings: It can effectively improve the glossiness of coatings, make the coating surface smoother and more flat, and have stronger ability to reflect light, presenting a bright appearance. At the same time, it helps to improve the leveling property of coatings, reduce surface defects such as flow marks and pinholes, and enable the coating to form a uniform and consistent coating after construction. In addition, it also has a certain effect on improving the weather resistance of coatings, enhancing the ability of the coating to resist the influence of external factors such as ultraviolet rays and rain erosion, and prolonging the service life of the coating.
- Good storage stability: Through its stable dispersion effect on pigments, it can effectively inhibit the sedimentation and coarsening of pigments during storage, ensuring that the coating can still maintain good uniformity and construction performance after long - term storage, and reducing the product quality degradation caused by storage problems.
Application Fields
- Automotive coating field: It is used in automotive original paint and automotive refinish paint, which can help improve the appearance quality of coatings, make the automotive paint surface brighter and flatter, and at the same time enhance the weather resistance and scratch resistance of the coating to protect the automotive body.
- Furniture coating field: It is applied to furniture coating, improving the gloss and leveling effect of furniture paint, making the coating on the furniture surface more beautiful, and at the same time improving the wear resistance and chemical resistance of furniture paint to better protect the furniture surface.
- Industrial protective coating field: It is used for protective coating of various industrial equipment, steel structures, etc. It can not only make the appearance of the coating more beautiful, but also enhance the protective performance of the coating, improve the ability of industrial facilities to resist corrosion, wear, etc., and prolong their service life.
Recommended Dosage
The specific dosage of BYK - 220S dispersant (in the purchased form, based on the percentage of pigments in the coating formula) varies with the coating system, pigment type and formula design. Generally, small - scale laboratory tests are needed to determine the optimal dosage. During the test, observe the dispersion effect, glossiness, leveling property and other performance indicators of the coating to achieve the best dispersion effect and comprehensive performance while controlling the cost.
Addition Method
In the coating production process, it is recommended to add BYK - 220S dispersant in the pigment pre - dispersion stage. The dispersant can be fully mixed with part of the solvent or water - based medium first, and then the pigment is added for dispersion operations such as stirring and grinding, so as to ensure that the dispersant is fully in contact with the pigment and exert the best dispersion effect.
Storage Conditions
It should be stored in a cool, dry and well - ventilated warehouse, avoiding direct sunlight and high - temperature environments. The storage temperature is generally recommended to be controlled 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 other substances and affecting the quality.
