Basic Information
- Brand Model: DISPER BYK - 2150
- Product Name: Dispersant
- Packaging Specification: 25 kg/blue iron drum
- Chemical Composition: Block copolymer solution containing basic pigment - affinic groups
Product Features
- Excellent Pigment Dispersibility: The basic pigment - affinic groups in DISPER BYK - 2150 can specifically adsorb with basic pigments, reducing the cohesion between pigment particles. It effectively prevents pigment flocculation and sedimentation, realizes uniform dispersion of pigments in the coating system, and improves the color stability and hiding power of the coating.
- Wide System Compatibility: As a universal wetting and dispersing agent, it is not only suitable for solvent - based coating systems but also well - adapted to resin - containing pigment concentrates with wide compatibility. Notably, it shows excellent compatibility with thermoplastic acrylic (TPA) and nitrocellulose systems, and can fully exert the wetting and dispersing effect in these systems without affecting the original performance and construction characteristics of the coating.
- Improve Coating Performance: Uniformly dispersed pigments help improve the gloss, leveling, weather resistance and other properties of the coating. In solvent - based coatings, it can make the surface of the paint film smoother and flatter, reducing surface defects such as orange peel and pinholes; in resin - containing pigment concentrates, it can enhance the stability of the concentrate after mixing with other coating components and ensure the consistency of coating quality.
- Optimize Construction Performance: By reducing the viscosity of the coating system and improving its fluidity, the coating becomes smoother during construction processes such as spraying, brushing or roller coating, improving construction efficiency and reducing construction problems caused by poor coating fluidity, such as sagging and insufficient coverage.
Application Fields
- Automotive Coating Field: In original equipment manufacturer (OEM) automotive paints and automotive refinish paints, it is used to disperse various pigments to ensure uniform and bright body colors, and at the same time improve the weather resistance and scratch resistance of the paint film to protect the appearance of automobiles.
- Wood Coating Field: In solvent - based wood coatings, it helps pigments disperse uniformly, endows wood with rich colors, and improves the gloss and wear resistance of the paint film to protect wooden furniture and decorative materials.
- Industrial Coating Field: It is suitable for protective and decorative coatings of various industrial equipment and metal components, enhances the adhesion and anti - corrosion performance of the coating to the substrate, and prolongs the service life of industrial products.
- Printing Ink Field: In printing inks prepared from resin - containing pigment concentrates, it ensures uniform dispersion of pigments, makes printed patterns bright and clear, and improves printing quality.
Recommended Dosage
The specific dosage of DISPER BYK - 2150 (based on the total amount of the coating system or resin - containing pigment concentrate in the purchased form) needs to be determined according to the type and content of pigments in the coating formula and specific application scenarios. It is generally recommended to conduct small - scale formula tests first, by observing the dispersion state, viscosity change, gloss, adhesion and other performance indicators of the coating, to determine the optimal addition amount that can ensure good dispersion effect without negatively affecting other properties of the coating.
Addition Method
In the production process of coatings or resin - containing pigment concentrates, it is recommended to add DISPER BYK - 2150 to the solvent or resin solution before adding pigments, stir evenly, and then gradually add pigments for sufficient dispersion. Equipment such as high - speed dispersers and sand mills can be used to ensure that the dispersant is fully in contact with the pigments to achieve efficient dispersion of the pigments.
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 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 absorbing moisture in the air or reacting with other substances, thereby affecting the product quality.
