Product Details
- Brand Model: DISPER BYK - 191
- Product Name: Dispersant
- Packaging Specification: 25 kg/blue iron drum
- Chemical Composition: Copolymer containing pigment - affinitive groups
Product Features
- Environmental Protection Attribute: It contains no VOCs (Volatile Organic Compounds) or solvents. During the production and application process, it significantly reduces the emission of harmful gases, meeting the current strict environmental protection standards. It is suitable for water - based coating and adhesive production scenarios with high environmental protection requirements, and also minimizes potential harm to the health of operators.
- Wide Applicability: It can be used in water - based coating systems and adhesives. It exerts excellent dispersing effects in both resin - free pigment concentrates and resin - containing pigment concentrates. Particularly suitable for emulsion systems, it can well compatible with components in emulsion systems and ensure the stability of the system.
- Efficient Dispersing Capacity: Relying on its pigment - affinitive groups, it can quickly and firmly adsorb on the surface of pigment particles, reduce the surface tension and cohesion between pigment particles. Thus, it realizes the uniform dispersion of pigments in water - based resins, prevents pigment flocculation and sedimentation, improves the dispersing effect of pigments and fillers in water - based resins, and makes the performance of coatings and adhesives more stable.
- Improve Product Performance: When used in water - based coatings, it helps to enhance the hiding power, color uniformity, gloss and other properties of coatings. When applied in adhesives, it can strengthen the wettability of adhesives on the surface of adherends and the adhesive force, improving the comprehensive performance of adhesives.
Application Fields
- Water - based Coating Field: It is applicable to water - based latex paints for interior walls, water - based coatings for exterior walls in the construction industry, as well as water - based metal paints and water - based wood paints in the industrial field. It can help optimize the production process of coatings, improve the quality of finished coatings, and meet the requirements for coating performance and environmental protection in different scenarios.
- Adhesive Field: It is used in various water - based adhesives, such as woodworking adhesives and packaging adhesives. It can improve the production and application performance of adhesives, enhance the bonding effect and stability, and at the same time meet the environmental protection requirements for adhesives in fields such as environmental protection packaging and home decoration.
Recommended Dosage
Due to differences in formulas of different water - based coating systems, adhesive formulas, as well as the types and proportions of pigments and fillers used, the specific dosage of DISPER BYK - 191 Dispersant (in the purchased form, based on the percentage of pigments and fillers in the system) needs to be determined through small - scale tests. Generally, adjust the addition amount step by step during the test, and observe indicators such as the dispersing effect and stability of the system to find the optimal addition amount, so as to balance the dispersing effect and cost.
Addition Method
It is recommended to add DISPER BYK - 191 Dispersant during the dispersion stage of pigments and fillers in the production process of water - based coatings or adhesives. First, dissolve the dispersant in a part of water - based medium (such as water), stir it evenly, and then add pigments and fillers for dispersion operations, such as high - speed stirring and grinding, to ensure that the dispersant is fully in contact with pigments and fillers and exerts the best dispersing effect.
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 is necessary to restore it to room temperature and stir it thoroughly to ensure stable product performance and no impact on the application effect.
