1. Basic Information
- Brand and Model: BYK - 077, produced by BYK - Chemie of Germany. BYK - Chemie has a high reputation and market share in the field of coating additives and focuses on providing various high - performance additive products for industries such as coatings and plastics.
- Packaging Specifications: Common packaging specifications include 20 kg/blue iron drum and 160 kg/blue iron drum, which are convenient for customers with different usage quantity requirements to choose.
- Composition: The main component is organosilicon. Due to its unique molecular structure, organosilicon materials have good surface activity, low surface tension and other characteristics, which enable BYK - 077 to play a special role in coating systems.
2. Product Performance
- Defoaming and Anti - Cratering: It can effectively prevent the formation of bubbles and craters in non - polar to highly polar solvent - based coatings during production and processing. In the processes of coating stirring, transportation and painting, air is easily involved to generate bubbles, and BYK - 077 can quickly eliminate these bubbles and avoid the occurrence of craters, thus ensuring the flatness and smoothness of the coating surface. For example, in the painting process of automobile metal parts, it can significantly improve the appearance quality of the coating.
- Recoat Friendliness: During recoating operations, this additive will not cause rewetting difficulties. Rewetting difficulties may lead to interface problems between the newly applied coating and the old coating, such as undercutting and peeling, while BYK - 077 can ensure a good combination between the new coating and the old coating. In addition, it will not affect the adhesion between coatings, ensuring the overall stability and durability of the coating system after multi - layer painting.
- Leveling Effect: It can improve the leveling performance of the coating, making the coating spread more evenly on the substrate surface. During the drying and film - forming process of the coating, it helps to form a flat and smooth paint film, reduce coating defects such as brush marks and roller marks, and improve the decoration and protection of the coating.
3. Application Fields
- Solvent - based Coatings: It is widely used in various solvent - based coating systems, including but not limited to automotive coatings (such as original automotive paint and automotive refinish paint), industrial coatings (such as metal anti - corrosion coatings, mechanical coatings, and wood coatings), coil coatings, etc. In these fields, BYK - 077 can adapt to coatings of different solvent systems (from non - polar solvents to highly polar solvents) and meet diverse painting requirements.
4. Usage Method and Recommended Dosage
- Usage Method: It is usually added in the paint mixing stage of coating production. It is recommended to add it slowly under low - speed stirring to ensure that it is evenly dispersed in the coating system and fully exerts its effect.
- Recommended Dosage: Generally, it is 0.1 - 1.0% of the total amount of the coating formula. However, in actual use, the specific addition amount needs to be determined through experiments according to the type of coating, formula composition, construction process (such as spraying, brushing, rolling, etc.) and specific requirements for coating performance.
5. Precautions
- Compatibility: Although BYK - 077 has good compatibility in most solvent - based coating systems, it is still recommended to conduct a compatibility test before use. Especially for some special formulas or new coating systems, incompatibility may occur, causing the coating to become turbid, delaminated, etc., which affects the coating quality and construction effect.
- Storage Conditions: It should be stored in a cool and dry environment, avoiding high temperature, direct sunlight and moisture. Good storage conditions help maintain the stable performance of the product and extend its shelf life.
- Environmental Protection and Safety: During use, relevant safety operating procedures and environmental protection requirements should be followed. Although organosilicon additives have good performance, they also need to be properly handled to avoid adverse effects on the environment and human health.
