1. Basic Information

• Brand and Model: BYK-346, produced by BYK (Germany), a company with advanced technology and rich experience in the additive field.
• Product Name: Leveling Agent
• Packaging Specifications: There are two specifications: 25 kg/blue iron drum and 190 kg/blue iron drum, meeting the needs of different purchase quantities.
• Composition: Polyether-modified siloxane, belonging to the category of silicone surfactants.

2. Product Performance

• Strongly Reduce Surface Tension: In water-based coatings, printing inks and varnish systems, it can significantly reduce the surface tension of the system, making coatings and inks easier to spread on the substrate surface, avoiding surface defects such as craters and fisheyes, and helping to form uniform and smooth coatings or printed patterns.
• Significantly Improve Substrate Wettability: It can greatly enhance the wetting ability to various substrates. Whether it is common substrates such as metals, plastics and papers, or some special substrates with low surface energy and difficult to wet, it can make coatings and inks adhere better and improve the bonding force between coatings or printed layers and substrates.
• No Increase in Surface Smoothness: While exerting leveling and wetting effects, it will not additionally increase the surface smoothness of coatings or printed layers. It is suitable for scenarios where there are specific requirements for surface touch and it is not desired to change the surface smoothness due to the use of leveling agents, such as some printed matter that requires a specific friction coefficient and water-based coatings that require a specific texture.

3. Application Fields

• Water-based Coatings: Widely used in various water-based industrial coatings, water-based architectural coatings, water-based wood coatings, etc. In water-based industrial coatings, it can optimize the leveling and adhesion of coatings on metal, plastic and other workpieces, and improve the protective performance and appearance quality of coatings; in water-based architectural coatings, it can improve the wetting of coatings to substrates such as walls and ceilings, making the surface after painting more smooth and uniform in color; for water-based wood coatings, it helps coatings to spread evenly on the wood surface, enhances adhesion, and does not affect the original texture of the wood surface.
• Printing Inks: Suitable for water-based inks in various printing processes such as gravure printing and flexographic printing. It can improve the transfer and adhesion effect of ink on substrates (such as paper, plastic films, etc.), make printed patterns clearer and colors more vivid, and reduce problems such as ink flying and plate blocking.
• Varnishes: Used in water-based varnish systems, it can promote the uniform distribution of varnish on the coating surface, improve the gloss and transparency of varnish, enhance the protective effect on the substrate, and will not affect subsequent processing or use due to changes in surface smoothness.

4. Usage Method

• Adding Method: It can be added during the grinding, paint mixing and other stages in the production process. To ensure uniform dispersion, it is recommended to add slowly under stirring and ensure sufficient stirring time to fully integrate the leveling agent into the system.
• Recommended Dosage: The general recommended addition amount is 0.05% - 0.5% of the total formula. The specific dosage needs to be determined through experiments according to the actual formula, process and performance requirements.

5. Precautions

• When storing, it should be placed in a cool, dry and ventilated place, avoiding direct sunlight and high-temperature environments to prevent the product performance from being affected.
• Before use, it is necessary to confirm the compatibility with other components in the system. If there are special requirements, a small test can be carried out for verification.
