Basic Information
- Product Name: Defoamer
- Brand and Model: BYK - 055
- Packaging Specifications: 25 kg/blue iron drum, 150 kg/blue iron drum
- Main Component: Non - silicon polymer, specifically a high - molecular compound obtained through a special polymerization process, which has the characteristics of high - efficiency defoaming.
Physical Properties
- Appearance: Usually a colorless to light yellow transparent or translucent liquid (The appearance may vary slightly due to production batches and raw material differences).
- Density: Approximately 0.9 - 1.1 g/cm³ (The actual value is subject to the product technical data).
- Flash Point: Relatively high, generally above 60°C, ensuring high safety during use and storage.
- Solubility: Can disperse in a variety of common solvent - based and solvent - free wood and furniture coating systems.
Application Fields
- Solvent - based Wood and Furniture Coatings: During the production of solvent - based clear and colored coatings, such as nitrocellulose lacquers and polyurethane paints, it can effectively eliminate foam generated by operations like stirring and pigment dispersion. This prevents defects such as pinholes and bubbles in the coating, improves the flatness and gloss of the coating, and enhances the decorative and protective effects on wood and furniture surfaces.
- Solvent - free Wood and Furniture Coatings: Suitable for water - based wood coatings, radiation - cured polyester coatings and other solvent - free systems. It solves the foam problem within the system, ensuring that the coating forms a uniform and smooth film after application, meeting environmental requirements while guaranteeing product quality.
- Wood and Furniture Coatings Based on Specific Systems: For coatings based on high - gloss polyester and radiation - cured polyester systems, the defoaming effect is particularly significant, which can better meet the strict requirements of high - end wood and furniture for coating appearance and performance.
- Epoxy Systems: In epoxy - based wood and furniture coatings, it can also effectively play a defoaming role to ensure the quality of the coating.
Performance Characteristics
- Efficient Defoaming: It has the ability to defoam quickly, which can rapidly reduce the surface tension of foam, making the foam break and disappear quickly, ensuring the smooth progress of coating production and application processes.
- Good System Adaptability: It has good adaptability to different types of wood and furniture coating systems (solvent - based, solvent - free, specific polyester systems, epoxy systems, etc.), and can stably perform defoaming functions in various formulations.
- Minimal Impact on Coating Performance: While defoaming, it will not have a significant negative impact on key performance indicators of the coating, such as adhesion, hardness, and wear resistance. However, when this additive is used in the coating of dark - colored wood, there may be a slight turbidity, but it has little impact on the overall performance of the coating film. Even in the case of a relatively thin film thickness, it can ensure better stability of the coating film.
- Environmental Advantages: It does not contain organosilicon components. Compared with some organosilicon defoamers, it has more advantages in environmental protection, meeting the current environmental requirements of the coating industry, and is suitable for the production of environmentally friendly wood and furniture coatings.
Recommended Dosage
Generally, it accounts for 0.1% - 1% of the total formula amount. The actual dosage needs to be flexibly adjusted according to factors such as the severity of foam in the coating system and the composition of the formula. For example, for complex formulas prone to generating a large amount of foam.
