Basic Information

• Brand and Model: BYK, DISPERBYK - 102
• Packaging Specification: 25 kg/blue iron drum
• Chemical Composition: Copolymer solution containing acidic groups

Product Characteristics

• Appearance and Physical Properties: Generally a colorless to pale yellow transparent liquid with no pungent odor (as it is solvent - free). The density is approximately 1.0 - 1.1 g/cm³ (at 20℃), and it has a relatively high flash point, ensuring good safety during storage and transportation. It has good solubility in polar and moderately polar solvents and also has certain compatibility with aqueous systems, facilitating dispersion and use in different coating systems.
• Core Functions
  • Enhance Pigment Dispersion Efficiency: Through the interaction between the copolymer molecules containing acidic groups and the surface of inorganic pigments, the attractive force between pigment particles is reduced to prevent agglomeration, enabling pigments to be uniformly dispersed in the coating system and improving tinting strength and color uniformity.
  • Improve Color Acceptance: Optimize the compatibility between general - purpose colorants and base coatings, avoiding problems such as color deviation and floating caused by poor pigment dispersion, and ensuring accurate and vivid final coating colors.
  • Expand Pigment Application Range: Especially suitable for inorganic pigments (such as titanium dioxide, iron oxide pigments, etc.). In solvent - based and water - based polar/moderately polar coatings, it can improve the wettability of pigments, making them perform better in coatings, reducing dosage and lowering costs.
  • Solvent - free Environmental Advantage: It does not contain volatile organic solvents (VOC), meeting environmental regulation requirements. It is suitable for coating systems with high environmental protection requirements, reducing environmental pollution and health risks during construction.

Application Fields

• Main Application Scenarios
  • Solvent - based Coatings: Used in original equipment manufacturer (OEM) automotive paints, industrial protective coatings, wood coatings, etc., to improve the dispersion stability of inorganic pigments in solvent - based systems and ensure the hiding power and color durability of coatings.
  • Water - based Coatings: Suitable for water - based industrial coatings, architectural coatings (such as exterior wall latex paints), solving problems such as easy sedimentation and uneven dispersion of inorganic pigments in water - based systems, and improving the application performance and storage stability of coatings.
  • General - purpose Colorants: Used in the preparation of color pastes or general - purpose colorants to enhance their compatibility with different base coatings and meet multi - scenario color matching needs.
• Applicable Systems: Solvent - based polar/moderately polar coatings (such as alkyd resin, acrylic resin, polyurethane systems) and water - based polar/moderately polar coatings (such as acrylic emulsion systems).

Recommended Dosage and Usage Methods

• Recommended Dosage: 1% - 5% based on the pigment amount (calculated by the purchased form). The specific dosage needs to be adjusted according to the pigment type, particle size, and coating system requirements. For example, for inorganic pigments with high specific surface area (such as nano - sized iron oxide), the dosage can be appropriately increased.
• Usage Methods
  • Solvent - based Systems: DISPERBYK - 102 can be added together with pigments during the grinding stage, and high - speed dispersion or sand milling can be used to promote pigment wetting and dispersion; it can also be added during the paint mixing stage to improve the redispersibility of the already ground pigments.
  • Aqueous Systems: It is recommended to add it during the pigment pre - dispersion stage and use it with dispersion equipment (such as a high - speed mixer) to ensure that the copolymer is fully adsorbed on the pigment surface to form a stable dispersion.

Storage and Transportation

• Storage Conditions: Store at a temperature of 5 - 35℃, avoid direct sunlight and freezing, store in a dry and ventilated place, and keep away from fire sources.
• Shelf Life: Under suitable storage conditions, the shelf life is usually 60 months.
• Transportation Requirements: Transport as a non - hazardous chemical, prevent packaging from collision and inversion, and avoid product leakage.

Competitive Advantages

• Excellent Performance: Compared with traditional dispersants, DISPERBYK - 102 has better dispersion effects on inorganic pigments, which can significantly improve color strength and stability. It is especially suitable for high - requirement industrial coatings and architectural coatings, meeting the high - end customers' needs for color consistency.
• Environmental and Solvent - free: With no VOC emissions, it conforms to the global environmental trend. It can help customers meet strict environmental regulations (such as EU REACH, China's VOC limit standards) and expand the green coating market.
• Wide Compatibility: It is suitable for both solvent - based and water - based polar/moderately polar systems, reducing customers' procurement costs for different dispersants and providing a one - stop solution that adapts to various coating formulations.
• High Cost - effectiveness: A small amount of addition can achieve efficient dispersion, reducing pigment dosage and energy consumption costs. In the long run, it can improve production efficiency and reduce quality risks, with significant comprehensive cost advantages.
• Technical Service Support: BYK provides professional formula optimization guidance and application technical support to help customers solve specific problems (such as pigment flocculation, color paste thickening, etc.) during the dispersion process and ensure the maximum performance of the product.
