In the coating and printing processes of industries such as paints, inks, and adhesives, insufficient wetting of the substrate, uneven leveling, as well as surface defects such as pinholes and orange peel texture, not only affect the appearance and texture of the products, but also may lead to a decline in the protective performance of the coating, increasing the rework costs. Our company has launched the product wetting agent 245, which is a polyether-modified poly siloxane type surfactant. With its low surface tension, excellent water solubility, and smoothness, it demonstrates outstanding substrate wetting and leveling performance in various water-based and solvent-based coating and ink systems, providing an efficient additive solution for the industrial coating field.


I. Core Physical and Chemical Properties of the Product


Product wetting agent 245 is a colorless to light yellow transparent liquid with an effective content greater than 99.8%. Its specific gravity is 0.025 to 0.049 at 25 degrees Celsius, with a refractive index of 1.449 to 1.451, a viscosity of 10 to 100 centipoises, a cloud point of 50 to 60 degrees Celsius, and it is soluble in water. This product belongs to a polyether-modified organic silicon structure. Through the synergistic effect of the siloxane chain segments and the polyether groups, it can significantly reduce the surface tension of the system, ensuring that the coating can spread quickly and penetrate the complex texture of the substrate at low viscosity.


II. Core Performance Advantages


Product wetting agent 245 exhibits the following core performance advantages in coating and ink systems:


Excellent substrate wetting and penetration performance. The product has low surface tension characteristics, which can effectively reduce the difficulty of wetting caused by high surface tension in water-based coatings, solving the wetting problems for low-energy surfaces such as metals, plastics, and wood.


Outstanding leveling and anti-shrinkage ability. During the coating film formation process, the product can inhibit the uneven evaporation of solvents, reduce turbulent flow and Benard vortices, and effectively prevent the occurrence of surface defects such as pinholes.


Good water solubility and smoothness. The product has excellent water solubility, which can reduce surface friction and give the coating a smooth feel and appearance, while not affecting the rework performance of the coating.


High-temperature resistance and compatibility advantages. The silicon-oxygen bond gives the product excellent thermal stability. It maintains the molecular configuration stable in high-temperature baking environments, avoiding the risk of traditional organic additives yellowing at high temperatures, and having good compatibility with other additives.


III. Wide Application Areas


Product wetting agent 245, with its multi-system applicability and excellent performance, can play a key role in the following coating and ink application fields, specifically including:


1. Water-based industrial paints and water-based wood coatings. The product can effectively reduce the surface tension of water-based coating systems, improve the wetting performance of the substrate, enhance the adhesion and salt spray resistance of the coating, and be suitable for various water-based industrial protective coatings and wood coating.


2. Water-based polyurethane and water-based acrylic systems. The product performs well in water-based polyurethane and water-based acrylic coatings, solving common problems of pinholes and poor leveling in water-based coatings, and improving the glossiness and smoothness of the coating film.


3. Water-based printing pastes and water-based varnish. The product can improve the wetting and spreading performance of printing pastes, enhance the clarity and color saturation of printed patterns, and be suitable for textile printing and packaging printing fields.


4. Dip coating paints and carpet adhesives. The product can improve the uniformity of the coating in dip coating processes and enhance the wetting and leveling effects of the adhesive system.


5. Water-based alkyd resins and other water-based systems. The product has good compatibility with water-based alkyd resins and other water-based resin systems, with a wide range of applications.


IV. Usage Suggestions and Recommended Dosage


The recommended dosage of product wetting agent 245 is 0.1% to 0.5% of the total volume of the coating or ink. The specific dosage should be determined through experimentation based on the formulation system and performance requirements. The product can be mixed evenly with the ink or paint and used directly, with convenient operation.


V. Packaging Specifications and Storage Conditions Product wetting agent 245 is sealed in plastic or iron drums of 25 kg, 50 kg or 200 kg capacity. It is stored in a cool, dry place at normal temperature. Under the conditions of meeting the above storage requirements and without being opened, the storage period is one year.


VI. Quality Assurance and Usage Tips


During the production process, a strict quality control system has been established for Product Wetting Agent 245. Key indicators such as product appearance, effective content, specific gravity, refractive index, viscosity and cloud point are tested throughout the process to ensure consistency and reliability between batches. The technical suggestions and data in this document are based on existing knowledge and are for reference only. It is recommended that users conduct small-scale trials before use to determine the optimal addition amount and applicable conditions.


With the continuous expansion of the water-based coatings and environmentally friendly inks markets, the demand for efficient additives that have the functions of wetting, leveling and anti-shrinkage has been steadily increasing. Product Wetting Agent 245, with its structural advantages of polyether-modified silicone oil, wide compatibility with various systems and stable quality performance, is becoming an important option for coating and ink manufacturers in choosing wetting and leveling additives, helping downstream industries improve coating quality and optimize processes.
