1. Basic Information

• Brand and Model: BYK - 307, developed and produced by BYK - Chemie of Germany. BYK - Chemie is a global leader in the field of additives for coatings and inks, renowned for its innovative technology and high - quality products.
• Packaging Specifications: Available in two packaging specifications: 25 kg/blue iron drum and 200 kg/blue iron drum, meeting the procurement and usage needs of different customers, whether for small - scale laboratory research and development or large - scale industrial production.
• Composition: The core component is polyether - modified polydimethylsiloxane, which belongs to organosilicon surface additives. This unique chemical structure enables it to combine the dual advantages of polyether and organosilicon, demonstrating excellent performance in different systems.

2. Product Performance

• Strongly Reduce Surface Tension: It can significantly reduce the surface tension of solvent - free and solvent - based coating systems, printing inks, and adhesive systems, enabling coatings, inks, etc. to achieve good spreading effects on various substrates such as metals, plastics, glass, and wood, effectively avoiding the generation of surface defects such as craters and fisheyes.
• Excellent Substrate Wetting Ability: With excellent surface activity, BYK - 307 has excellent wetting effects on various substrates. Even for substrates with high surface tension or relatively rough surfaces, it can ensure that coatings or inks are fully covered, enhance adhesion, and improve the quality and durability of final products.
• Prevent Craters and Increase Smoothness: It effectively inhibits the formation of craters, ensuring the smoothness of the coating or printed product surface; at the same time, it endows the surface with good smoothness, reduces the friction coefficient, and improves the touch and wear resistance. It is especially suitable for products with high requirements for surface texture, such as high - end furniture and electronic product shell coatings.
• Solvent - free and Adaptation to Special Systems: As a high - efficiency organosilicon additive without solvents, it is especially suitable for systems with strict requirements on solvent residues, such as food packaging coatings and medical device coatings; at the same time, it can also maintain good compatibility and stable performance for intermediate systems using special solvents.
• Wide System Applicability: It is not only suitable for coating and adhesive systems but also can play an excellent leveling effect in various printing inks (such as offset printing inks, gravure inks, flexographic inks, etc.) and varnishes, improving the ink transfer performance and enhancing the clarity and color uniformity of printed patterns. In addition, it can also be applied to water - containing systems to solve the common leveling problems of water - based coatings and inks.

3. Application Fields

• Coating Field: Covers solvent - free coatings (such as thick - film anticorrosive coatings, photocurable coatings) and solvent - based coatings (original automotive paints, automotive refinish paints, industrial anticorrosive paints, wood coatings, etc.), effectively improving the appearance and performance of coatings.
• Printing Field: Suitable for various printing ink systems, optimizing the leveling and drying performance of inks during the printing process, improving the quality of printed products, and reducing the rejection rate.
• Adhesive Field: In adhesive systems such as structural adhesives and sealants, it improves the coating performance of adhesives and their wetting ability to adherends, enhancing the bonding effect.
• Special Industries: In industries with extremely high requirements for safety and performance, such as food packaging, medical devices, and electronic appliances, BYK - 307 has become an ideal leveling solution due to its solvent - free and high - performance characteristics.

4. Usage Method and Recommended Dosage

• Usage Method: It is recommended to add during the paint mixing and preparation stage of coating, ink, or adhesive production, and add slowly with low - speed stirring to ensure that BYK - 307 is evenly dispersed in the system and fully exerts its leveling effect.
• Recommended Dosage: Generally, it is 0.1% - 1.0% of the total formula amount. However, the specific dosage needs to be accurately adjusted through experiments according to the system type (such as resin type, solvent property), construction process (spraying, brushing, printing method), and requirements for the performance of the final product. For example, in high - solid coatings, the dosage can be appropriately increased to ensure good leveling; while in varnishes with high gloss requirements, the dosage needs to be carefully controlled to avoid affecting the gloss.

5. Precautions

• Compatibility Test: Although BYK - 307 has good compatibility in most systems, before use, especially for new or special formula systems, a compatibility test must be carried out to prevent incompatible phenomena such as turbidity, delamination, and flocculation, which may affect product quality and use effect.
• Storage Conditions: It should be stored in a cool, dry, and well - ventilated environment, avoiding direct sunlight and high - temperature environments. The storage temperature is recommended to be controlled between 5°C and 30°C. Good storage conditions help maintain the stable performance of the product and extend its shelf life.
• Safety Protection: During use, relevant safety operating procedures should be followed to avoid direct contact with skin and eyes. In case of accidental contact, rinse immediately with plenty of water and seek medical attention in a timely manner. In addition, the use site should maintain good ventilation to prevent potential risks caused by the accumulation of volatile organosilicon additives.
