1. Basic Information
- Brand and Model: BYK - 310, produced by BYK - Chemie of Germany. The brand has world - leading technological R & D capabilities in the field of coating additives and focuses on providing high - performance solutions for industrial coatings, printing inks, and other fields.
- Packaging Specifications: 25 kg/blue iron drum and 175 kg/blue iron drum, meeting the different needs of laboratory research and development, small - batch production, and large - scale industrial applications. The packaging design is convenient for handling and storage.
- Composition: Polyether - modified polydimethylsiloxane (an organosilicon - based surface additive). Through the molecular design of polyether segments and siloxane chains, it has both low surface tension and excellent thermal stability.
2. Core Performance
- Efficiently Reduce Surface Tension: It significantly reduces the surface tension of solvent - free coatings, solvent - based coatings, printing inks, adhesives, and room - temperature curing plastic systems, promotes the uniform spreading of coatings on low - surface - energy substrates such as metals, glass, and plastics, and effectively prevents defects such as craters and fisheyes. For example, in the high - temperature baking paint for automobile hubs, it can ensure that the paint film is smooth and flat.
- Excellent Thermal Stability: With a thermal stability of up to 210 °C, it is suitable for high - temperature curing coating systems (such as coil coatings, powder coatings) and plastic molding processes that require high - temperature processing. It can still maintain a stable leveling effect in high - temperature environments and avoid coating defects caused by the decomposition of additives.
- Broad System Applicability:
- Solvent - free/solvent - based coatings: Compatible with resin systems such as epoxy, polyurethane, and acrylic, improving the leveling property of thick - film anticorrosive coatings and UV - cured coatings;
- Printing inks: Improve the transfer performance of offset and gravure inks, reduce ink film craters, and improve the clarity of printed patterns;
- Adhesives and plastics: Optimize the wetting ability during the coating process of structural adhesives and inhibit the generation of bubbles during the curing of unsaturated polyester plastics.
- Surface Smoothness and Protection: It endows the coating with a delicate and smooth touch, reduces the friction coefficient, and at the same time enhances scratch resistance, which is suitable for scenarios with high wear - resistance requirements such as furniture paint and electronic device casings.
3. Application Fields
- High - temperature Coating Systems: Coil coatings (requiring 180 - 200 °C baking), original automobile paints (high - temperature baking paint process), powder coatings, etc., using its thermal stability to ensure the leveling effect during the high - temperature film - forming process.
- Industrial Coatings and Adhesives: Metal anticorrosive coatings, wood coatings, structural adhesives, etc., solving the wetting problems of complex substrates and improving adhesion and appearance quality.
- Printing and Plastics Industry: Food - grade inks for packaging and printing, unsaturated polyester plastics (such as fiberglass products), optimizing the production process and improving the qualified rate of finished products.
4. Usage Method and Dosage
- Adding Stage: It is recommended to add during the paint mixing stage of coating/ink production or before the curing of adhesive/plastic systems. Add slowly under low - speed stirring to ensure uniform dispersion and avoid introducing bubbles due to high - speed stirring.
- Recommended Dosage: 0.1% - 1.0% of the total formula amount. The specific dosage needs to be adjusted according to the system type:
- The dosage can be increased to 0.5% in high - temperature coil coatings to resist surface tension fluctuations at high temperatures;
- It is recommended to use 0.2% - 0.4% in solvent - based wood coatings to balance leveling property and recoat adhesion.
5. Precautions
- Compatibility Test: Although suitable for most systems, in formulas containing strongly polar solvents (such as DMF) or fluorocarbon resins, compatibility tests need to be carried out in advance to avoid turbidity or delamination.
- Storage and Transportation: Store in a cool and dry place (5 - 30 °C), away from heat sources; prevent exposure to the sun during transportation, and the shelf life of unopened packages is 24 months.
- Safe Operation: Wear protective gloves during operation to avoid direct contact with the skin; if it accidentally gets into the eyes, rinse immediately with plenty of water and seek medical attention.
