Basic Information

• Brand and Model: BYK, BYK - 425
• Packaging Specification: 25 kg/blue iron drum
• Chemical Composition: Urea - modified polyurethane solution

Product Characteristics

• Appearance and Physical Properties: Usually a colorless to pale yellow transparent or translucent liquid with no pungent odor. The density is generally 1.0 - 1.1 g/cm³ (at 20℃), and it has a relatively high flash point, which makes it safer during storage and transportation. It has good dispersibility in aqueous systems, and the kinematic viscosity is moderate, facilitating addition and mixing during the production process.
• Core Functions
  • Adjusting Viscosity in the Tank: Precisely controls the viscosity of the aqueous system during storage, preventing phenomena such as precipitation and delamination of the coating in the tank, ensuring that the coating has a uniform and stable state before use, which is convenient for construction operations.
  • Improving Anti - Sagging Property: Enhances the anti - sagging performance of water - based coatings during construction, so that the coating can be evenly distributed when applied on vertical surfaces, avoiding defects such as flow marks and sagging, and ensuring the flatness and aesthetics of the coating.
  • Anti - Settling Performance: Effectively prevents solid particles such as pigments and fillers from settling in the aqueous system, ensuring that all components of the coating are evenly dispersed during storage and use, and maintaining the stability of properties such as the hiding power and color uniformity of the coating.
  • Optimizing Grinding and Dispersion: When grinding color pastes, it increases the viscosity of the grinding material, improves the grinding conditions, enables pigments and fillers to be more fully dispersed, improves the quality of the color paste, and thereby enhances the color vividness and stability of the final product.

Application Fields

• Main Application Scenarios
  • Water - based Coatings: Widely used in architectural water - based coatings (such as interior and exterior wall latex paints), industrial water - based coatings (such as automotive water - based paints, metal protective water - based coatings), etc., to improve the construction performance and storage stability of coatings.
  • Printing Inks: Used in water - based printing inks to help control the rheological properties of the ink, ensure uniform transfer of the ink during the printing process, improve printing quality, and make printed patterns clearer and colors more 饱满.
  • Adhesives: In water - based adhesive systems, it adjusts the viscosity of the adhesive, improves its construction performance, and at the same time enhances the stability of the adhesive during storage, ensuring the reliability of the bonding effect.

Recommended Dosage and Usage Methods

• Recommended Dosage: 0.1% - 1% based on the total formula (calculated by the purchased form). The specific dosage needs to be adjusted according to factors such as the type of aqueous system and the desired performance effect.
• Usage Methods: It can be added during the paint mixing stage or grinding stage in the production process of the aqueous system. When adding, it is recommended to add slowly and stir continuously to ensure that the additive can be uniformly dispersed in the system and fully exert its performance.

Storage and Transportation

• Storage Conditions: It is recommended to store at a temperature of 5 - 35℃. The storage environment should be dry and well - ventilated, avoiding direct sunlight and freezing. Keep away from fire sources and strong oxidants to prevent danger.
• Shelf Life: Under the condition of complying with storage conditions, the shelf life of the product is usually 60 months.
• Transportation Requirements: Transport as general chemicals. During transportation, prevent collision and inversion to avoid packaging damage leading to product leakage.

Competitive Advantages

• Comprehensive and Efficient Performance: BYK - 425 integrates multiple functions such as adjusting viscosity, improving anti - sagging property, preventing settlement, and optimizing grinding and dispersion. Compared with additives with a single function, it can solve problems in the production, storage and construction of aqueous systems more comprehensively and improve product quality.
• Environmental Advantage: It does not contain VOC (Volatile Organic Compounds), which meets the current environmental regulations and market demand for environmentally friendly products. It provides customers with green and environmentally friendly solutions, which helps enterprises meet environmental requirements and expand the market.
• Wide Applicability: It has good compatibility with various water - based coatings, printing inks and adhesive systems, and can cover many application fields to meet the diverse needs of different customers.
• High Cost - Effectiveness: A proper amount of addition can significantly improve product performance. From the perspectives of reducing product quality problems, improving production efficiency, and reducing maintenance costs, it can bring relatively high comprehensive benefits to customers, and the cost - effectiveness ratio is high.
• High - Quality Service: BYK provides professional technical support, including formula optimization suggestions, technical guidance during application, etc., as well as perfect after - sales service, which can promptly respond to and solve problems encountered by customers during use.
