1. Basic Information

• Brand and Model: BYK - 313, manufactured by BYK - Chemie, Germany. Renowned for innovative technologies and high - quality products, BYK - Chemie specializes in providing high - performance solutions for industrial coatings.
• Packaging Specification: 25 kg/blue iron drum, suitable for laboratory research, small - to medium - scale production, and industrial applications. The packaging design facilitates storage and transportation.
• Composition: Polyester - modified polydimethylsiloxane (silicon - containing surface additive). Through the molecular design of polyester segments and siloxane, it combines low surface tension with excellent thermal stability.

2. Core Performance

• Powerful Surface Tension Reduction: Significantly reduces the surface tension of solvent - based coating systems, promoting uniform spreading of coatings on low - surface - energy substrates such as metals, glass, and plastics. It effectively prevents surface defects like craters and fisheyes. For example, in automotive original factory high - temperature baking paints, it ensures a smooth and flawless paint film.
• Exceptional Thermal Stability: With a thermal stability of up to 230°C, far exceeding that of conventional leveling agents, it is especially suitable for high - temperature baking systems (such as coil coatings, appliance metal paints). It maintains stable leveling performance during high - temperature film formation, avoiding coating defects caused by additive decomposition.
• Superior Substrate Wetting: Exhibits excellent wetting ability on complex substrates (such as galvanized steel sheets, anodized aluminum), enhancing coating adhesion and reducing coating problems caused by differences in substrate surface tension.
• Surface Smoothness and Protection: Endows the coating with a delicate and smooth touch, reduces the friction coefficient, and improves scratch resistance, making it ideal for scenarios with high requirements for surface texture, such as furniture paints and electronic device casings.
• Optimized for Baking Systems: Specifically designed for baking processes, it can quickly migrate to the coating surface during high - temperature curing, balance surface tension, and optimize the leveling effect, without affecting inter - coating adhesion and recoating performance.

3. Application Fields

• High - Temperature Baking Coatings:
  • Coil Coatings (180 - 230°C baking): Ensures uniform coating on metal coils, enhancing weather resistance and decorative properties.
  • Automotive Original Factory Paints (high - temperature baking process): Improves paint surface leveling and reduces orange peel effects.
  • Appliance Metal Coatings: For example, coatings on refrigerator and washing machine casings, enhancing surface flatness and wear resistance.
• Industrial Solvent - Based Coatings: Metal anti - corrosion coatings, coatings for construction machinery, wood coatings, etc., solving wetting problems on complex substrates and improving the appearance and protective performance of coatings.

4. Usage and Dosage

• Adding Stage: It is recommended to add during the paint - mixing stage of coating production. Slowly add under low - speed stirring to ensure uniform dispersion, and avoid direct addition in high - temperature environments to prevent additive volatilization.
• Recommended Dosage: 0.1% - 0.8% of the total formula amount. The specific dosage needs to be adjusted according to the system:
  • In high - temperature coil coatings, the dosage can be increased to 0.5% - 0.8% to resist surface tension fluctuations at high temperatures.
  • In solvent - based wood coatings, it is recommended to use 0.2% - 0.4% to balance leveling and recoating adaptability.

5. Precautions

• Compatibility Test: Although suitable for most solvent - based systems, in formulations containing strongly polar solvents (such as ketones) or special resins (such as fluorocarbon resins), a compatibility test should be conducted in advance to avoid turbidity or delamination.
• Storage Conditions: Store in a cool, dry place (5 - 30°C), away from heat sources and open flames. The shelf life of unopened packages is 24 months.
• Safety Protection: Wear protective gloves and goggles during operation to avoid direct contact with skin and eyes. In case of accidental contact, rinse immediately with plenty of water and seek medical attention.
