In the formulation design of coatings, inks and various surface coatings, surface additives that can reduce surface tension, enhance substrate wetting performance and improve coating smoothness are key factors for ensuring coating quality and construction adaptability. Our company's product leveling agent 3000, as a polyether-modified organic polysiloxane type surface additive, relies on its core mechanism of reducing the surface tension of the coating to improve the substrate wetting ability, as well as its comprehensive performance of increasing surface smoothness, abrasion resistance, anti-sticking, improving leveling and enhancing glossiness, and is suitable for various coating systems such as solvent-based, non-solvent-based and water-based systems, providing an efficient additive solution for the coating and ink industry.


I. Core Physical and Chemical Properties of the Product


Product leveling agent 3000 is a colorless to light amber liquid, with a specific gravity of 0.036 at 25 degrees Celsius. Its viscosity is 300 to 1200 centipoise, its refractive index is 1.4492, and the 0.1% aqueous solution has a cloud point of 38 degrees Celsius when mixed with water, with a surface tension of 22.7 millinewtons per meter, and the effective content is above 99%. The high effective content and low surface tension characteristics enable it to exhibit significant wetting and leveling effects at a low addition amount.


II. Core Performance Advantages


Product leveling agent 3000, as a polyether-modified organic silicone surface additive, exhibits the following core performance advantages in the coating and ink systems:


Reducing surface tension and substrate wetting. The product can effectively reduce the surface tension of the coating and significantly improve the wetting ability of the coating on various substrates, effectively preventing the occurrence of surface defects such as pinholes, fish eyes, and bubble points.


Increasing surface smoothness and abrasion resistance. The organic silicon chain segments give the coating excellent smoothness and abrasion resistance, enhancing the surface hardness and scratch resistance of the coating, and prolonging the decorative effect and service life of the coating.


Anti-sticking and improving leveling. The product has good anti-sticking performance, avoiding mutual adhesion of the coating during stacking or rolling, and improving the leveling of the coating, reducing orange peel and wave patterns.


Improving glossiness and preventing Benard vortices. The product can improve the glossiness of the coating, making the surface of the coating more full and bright, and effectively preventing Benard vortices caused by solvent evaporation and surface tension gradients, ensuring the uniformity of the coating.


III. Wide Application Areas


Product leveling agent 3000, with its multi-system applicability and excellent comprehensive performance, can play a key role in the following coating and ink application areas, specifically including:


1. Solvent-based coating systems. In various solvent-based industrial coatings, automotive paints, wood coatings, and plastic coatings, the product can effectively improve the leveling, glossiness and scratch resistance of the coating, enhancing the decorative and durability of the coating, with a recommended dosage of 0.05% to 0.5% of the total formula.


2. Non-solvent-based coating systems. In high-solid content coatings and powder coatings, the product can help overcome the inherent difficulties of high viscosity systems in leveling, promoting full leveling of the coating before curing, reducing surface defects, with a recommended dosage of 0.3% to 1% of the total formula.


3. Water-based coating systems. In water-based wood coatings, water-based industrial coatings, water-based architectural coatings, latex paints, and water-based pigment systems, the product can effectively reduce the shrinkage and leveling problems caused by high surface tension of water-based coatings, improving the smoothness and anti-sticking performance of the coating, with a recommended dosage of 0.3% to 1% of the total formula.


4. Water-based ink and neutral ink systems. In various water-based ink and neutral ink formulations, the product can improve the printing adaptability and leveling of the ink, making the printing patterns more full and delicate, enhancing glossiness, and strengthening the wear resistance and scratch resistance of the ink film.


IV. Usage Suggestions and Recommended Dosages The product leveling agent 3000 has a small dosage but remarkable effect. The recommended addition amounts for different systems are as follows: for oil-based systems, the recommended dosage is 0.05% to 0.5% of the total formula; for solvent-free systems, the recommended dosage is 0.3% to 1% of the total formula; for water-based systems (including water-based pigments, coatings, latex paints, water-based inks, and neutral inks), the recommended dosage is 0.3% to 1% of the total formula. The product can be added at any stage of the production process. For ease of use, it can be diluted with an appropriate solvent before adding to ensure uniform dispersion in the system.
