Packaging Specifications: 25 kg/blue iron drum (suitable for laboratory research, small - scale production testing, and small - volume procurement by small enterprises) and 200 kg/blue iron drum (suitable for large - scale industrial production enterprises, which can effectively reduce unit packaging costs and procurement frequency)
Chemical Composition: Acrylate copolymer with pigment - affinic groups. This special structure enables the dispersant to be accurately adsorbed on the pigment surface, laying a foundation for the subsequent dispersion and stabilization process.
Product Characteristics
Appearance and Physical Properties:It is usually a colorless to pale yellow transparent liquid with no pungent odor, which will not adversely affect the production operation environment. At 20°C, the density is between 1.0 - 1.1 g/cm³, and it has good fluidity. Its flash point is higher than that of common solvent - based additives, and it is safe during storage and transportation. At the same time, it has good compatibility with various solvent - based coating systems and printing ink systems, and can be quickly and evenly dispersed in them without stratification, turbidity and other phenomena.
Core Functions
Deflocculation and Stable Dispersion: With its high molecular weight, BYK - 116 effectively breaks the flocculation structure of pigments through steric hindrance stabilization, so that pigment particles are uniformly dispersed in the system in the form of single or small aggregates. At the same time, it imparts charge to pigment particles, and uses the repulsion between charges to prevent pigment particles with different charges from flocculating again, so as to ensure that the pigments always maintain a good dispersion state during the storage and use of coatings or inks.
Improve Optical Properties: The particle size of the deflocculated pigment is reduced, which can effectively improve the gloss of the coating film or printed matter, making its surface brighter and smoother. And after the pigment is uniformly dispersed, the tinting strength is significantly improved, and a more vivid and full color effect can be achieved with less pigment. In addition, it can also increase the transparency of the system (for transparent pigment systems) or hiding power (for opaque pigment systems) to meet the optical performance requirements of different application scenarios.
Improve Construction Performance: The dispersant can effectively reduce the viscosity of the coating or ink system, making it have better fluidity and leveling. During construction, such as spraying, brushing, printing, etc., it is easier to operate, which can reduce the generation of defects such as flow marks and brush marks, and help to achieve a more uniform and high - quality coating or printing effect. Moreover, the lower viscosity is also conducive to increasing the amount of pigment added, and further reducing production costs without affecting the system performance.
Application Fields
Main Application Scenarios
Automotive Coatings: In original automotive paints and automotive refinish paints, it is used to disperse various inorganic and organic pigments to ensure uniform color, high gloss and improve the aesthetics and quality of the car appearance.
Industrial Coatings: It is widely used in industrial fields such as metal protective coatings, mechanical equipment coatings, and container coatings. It can enhance the weather resistance, corrosion resistance and other properties of coatings, and at the same time ensure the stability and consistency of coating colors to meet the dual needs of industrial products for appearance and protection.
Wood Coatings: Suitable for solvent - based wood lacquers, such as furniture lacquers and floor lacquers. It can make the wood surface show high gloss and bright color effects, and at the same time enhance the wear resistance and scratch resistance of the paint film.
Printing Inks: In printing fields such as gravure printing, flexographic printing, and offset printing inks, it can effectively disperse pigments to ensure that printed matter has bright colors and distinct layers, and improve printing quality and efficiency.
Applicable Systems: Solvent - based coating systems, including alkyd resins, acrylic resins, polyurethane resins, epoxy resins, etc.; and solvent - based printing ink systems, such as nitrocellulose inks and polyamide inks.
Recommended Dosage and Usage Methods
Recommended Dosage: Calculated based on the total weight of pigments in the formula, the general recommended addition amount is 0.5% - 3%. The specific dosage will be adjusted according to factors such as the type of pigment, particle size, and the complexity of the system. For example, for some difficult - to - disperse pigments or systems with high pigment content, the dosage may need to be appropriately increased to 3% - 5% to ensure the ideal dispersion effect.
Usage Methods
Addition in Pre - Dispersion Stage: In the pre - dispersion stage of coating or ink production, add BYK - 116 together with pigments, solvents and part of resins into a high - speed disperser for preliminary mixing and dispersion. This can make the dispersant fully adsorbed on the pigment surface, prepare for the subsequent grinding and dispersion process, and improve dispersion efficiency.
Addition in Grinding Stage: It can also be added in the grinding stage, such as in equipment such as sand mills and ball mills, the dispersant is added together with pigments, resins, solvents, etc. for grinding. During the grinding process, the dispersant can better play the role of deflocculation and dispersion stabilization, so that the pigment particle size can reach a finer level.
Supplementary Addition in Paint/Ink Adjustment Stage: If the viscosity, dispersion effect, etc. of the system do not meet expectations after grinding, an appropriate amount of BYK - 116 can be added in the paint or ink adjustment stage. After adding, it needs to be fully stirred to ensure that the dispersant is fully mixed with the entire system.
Storage and Transportation
Storage Conditions: It should be stored in a cool, dry and well - ventilated environment at 5 - 35°C, avoiding direct sunlight and high temperature. The storage container should be kept sealed to prevent moisture, impurities from entering and solvent volatilization, which will affect product quality.
Shelf Life: Under the condition of complying with the storage conditions, the product shelf life is 60 months, calculated from the production date marked on the production batch number.
Transportation Requirements: It is transported as a non - dangerous chemical. During transportation, severe collision and inversion should be avoided to prevent damage to the packaging barrel and product leakage. When transporting in summer, pay attention to avoiding long - term exposure to the sun; when transporting in winter, generally no special thermal insulation measures are required, unless the transportation environment temperature is extremely low, which may cause the product to solidify, and appropriate thermal insulation measures need to be taken at this time.
Competitive Advantages
Excellent Dispersion Performance: Compared with similar dispersants on the market, BYK - 116 has more prominent deflocculation and stable dispersion effects on pigments, and can achieve uniform dispersion of pigments in various complex systems to ensure stable product performance.
Comprehensive Performance Improvement: It can not only achieve good dispersion of pigments, but also improve the optical performance (gloss, tinting strength, transparency/hiding power) and construction performance (reducing viscosity, improving leveling) of products at the same time, providing customers with a one - stop solution without using a variety of additives to solve different problems separately.
Wide Applicability: Suitable for a variety of solvent - based coating and printing ink systems, customers do not need to replace dispersants for different product systems, which reduces the difficulty and cost of formula adjustment, and also reduces the complexity of procurement and inventory management.
Brand and Technical Support: As a well - known brand in the industry, BYK has a strong technical R & D team and a complete after - sales service system. It can provide customers with professional technical consultation, formula optimization suggestions and timely after - sales problem solutions, helping customers quickly solve various problems encountered in the production process and improve production efficiency and product quality.
