Product Details
- Brand Model: BYK - 190
- Product Name: Dispersant
- Packaging Specifications: 25 kg/blue iron drum, 195 kg/blue iron drum
- Chemical Composition: Solution of high - molecular - weight block copolymers with pigment - affinitive groups
Product Features
- Environmental Protection Property: Free of VOC (Volatile Organic Compounds) and solvents, it meets the current strict environmental protection requirements. During production and use, it can reduce environmental pollution and harm to the health of operators, and is suitable for fields such as water - based coatings, printing inks and adhesives with high requirements for environmental protection indicators.
- Wide Applicability: It can be used in water - based coating systems, printing inks and adhesives. As a standard additive for resin - free pigment concentrates, it is suitable for various types of pigments, such as organic pigments and inorganic pigments, and can effectively improve the dispersion effect of pigments in different systems.
- Efficient Dispersion and Stability: With the structure of high - molecular - weight block copolymers containing pigment - affinitive groups, it can quickly and fully wet pigments, reduce the interaction force between pigment particles, make pigments uniformly dispersed in the system, effectively prevent pigment flocculation and sedimentation, and ensure the stability of the system. It is especially suitable for producing stable resin - free pigment concentrates with a pigment content of 30 - 60%, ensuring the stable performance of the concentrates during storage and use.
- Good Compatibility: It has good compatibility with standard water - based binders, such as acrylic dispersions or water - soluble acrylic resins. During the paint mixing process, it can make the pigment concentrates better integrate with the water - based binders and improve the performance and quality of the final product.
Application Fields
- Water - based Coating Field: In the production of architectural water - based coatings (such as interior wall latex paints, exterior wall coatings) and industrial water - based coatings (such as automotive water - based paints, metal protective water - based paints), it is used to prepare pigment concentrates, helping to improve the color stability, hiding power, gloss and other properties of coatings while meeting environmental protection requirements.
- Printing Ink Field: Suitable for water - based printing inks, it can improve the dispersibility of pigments in inks, make the colors of printed matter more vivid and uniform, improve printing quality, and meet the requirements for environmental protection inks such as food packaging.
- Adhesive Field: Used in the production of water - based adhesives, it enhances the performance and appearance quality of adhesives by effectively dispersing fillers and pigments, while reducing the release of harmful substances.
Recommended Dosage
The dosage of the additive (in the purchased form, based on the percentage of pigments in the system) varies depending on the specific application system, pigment type and desired effect. It is generally recommended to determine the optimal dosage through small - scale formula tests before use to achieve the best dispersion effect and cost - effectiveness.
Addition Method
When preparing resin - free pigment concentrates or related systems, it is recommended to add BYK - 190 dispersant in the pigment pre - dispersion stage. First, fully mix the dispersant with part of the water - based medium, and then add pigments for dispersion operations such as stirring and grinding to ensure that the dispersant is fully contacted with the pigments and exerts 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 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.
