4. Application Fields

1. Coatings Industry: Suitable for solvent-based, solvent-free and water-based coatings, such as automotive coatings, architectural coatings, wood coatings, industrial coatings, etc. It can improve the adhesion, leveling and gloss of coatings on different substrates, and reduce coating defects. In automotive coatings, it can make the body paint surface smoother and flatter, and improve gloss and durability; when used in wood coatings, it can enhance the protection and decoration effect of the coating on the wood surface.
2. Printing Ink Field: Widely used in various printing inks. It can improve the transfer performance of ink during printing, enhance the wettability of ink to the substrate, make the printed pattern clearer and the color more vivid. At the same time, it prevents problems such as ink flying and ink stacking during the printing process.
3. Adhesives and Sealants Industry: It can enhance the adhesion of adhesives and sealants to different materials, improve their spreadability on complex surfaces, and enhance sealing performance, ensuring that adhesives and sealants can play a stable role in various environments. It is especially suitable for polyurethane, epoxy and acrylate adhesives, which can significantly improve their wetting effect on the substrate.
4. Room Temperature Curing Plastic Systems: When used in polyurethane and epoxy-based room temperature curing plastics, it can enhance the surface wetting of the system on harsh substrates, improve the surface quality and performance of the cured plastic, and reduce defects such as bubbles and shrinkage marks.

5. Recommended Dosage

1. Solvent-based and solvent-free coatings: 0.05 - 0.3% based on the total formula.
2. Printing inks: 0.05 - 0.3% based on the total formula.
3. Varnishes: 0.05 - 0.3% based on the total formula.
4. Water-based coatings and UV coatings: 0.05 - 1% based on the total formula.
5. Adhesives and sealants: 0.05 - 0.3% based on the total formula.
6. Polyurethane, epoxy and acrylate adhesives: 0.05 - 0.3% based on the total formula.
7. Polyurethane and epoxy-based room temperature curing plastics: 0.05 - 0.3% based on the total formula.

The actual dosage needs to be determined through a series of tests according to the specific formula, production process and product performance requirements to achieve the best use effect.

6. Addition Method and Processing Guidance

It can be added at any stage of the production process, including post-addition. To reduce the foaming effect of the additive, it is recommended to add it at the final stage of manufacturing. When adding, it can be added directly to the system, or it can be added after being diluted with an appropriate solvent. During the addition process, sufficient stirring and mixing must be ensured to make the additive evenly dispersed in the system.

7. Special Reminder

Compared with traditional silicone oil, BYK-333 is relatively safe to use. However, before large-scale use, tests should be carried out to confirm its foaming stability, recoatability and crater tendency in the system to ensure that it is compatible with the entire production system and avoid negative impacts on product quality.

8. Storage and Transportation

1. Storage: When the storage temperature is lower than 5°C, the product may become turbid and layered. Before use, it needs to be heated to 20°C and mixed thoroughly, which does not affect the product performance. It is recommended to store at a temperature between 5 - 40°C, and the shelf life is as long as 60 months. It should be placed in a dry, cool and ventilated place, avoiding direct sunlight and high-temperature environments, and keeping the package sealed to prevent moisture and impurities from entering.
2. Transportation: Transport in accordance with the general chemical transportation requirements. During transportation, avoid severe collision, extrusion and rain to ensure that the product packaging is intact.
