In the production processes of water-based coatings, printing inks, and synthetic leathers, surface defects such as pinholes and shrinkage cavities caused by poor substrate wetting, as well as foam problems caused by traditional wetting agents during high-speed construction processes, have long plagued formulation engineers and manufacturing enterprises. Our company has launched the product 4100, a non-foaming type defoaming wetting agent, which is a special modified poly siloxane copolymer. With its unique allyl alcohol modified organic silicon bifacial structure design, it integrates substrate wetting, anti-shrinkage, promoting flow, and defoaming performance. In water-based polyurethane, water-based acrylic, and water-based epoxy systems, it demonstrates outstanding comprehensive performance, providing efficient additive solutions for the industry.


I. Core Physical and Chemical Properties of the Product


Product 4100, a non-foaming type defoaming wetting agent, is a light yellow transparent liquid with 100% active substance content. It can be directly used without additional dilution. At 25 degrees Celsius, its refractive index ranges from 1.440 to 1.450, and its viscosity is 20 to 60 centipoises. At a concentration of 0.1%, the surface tension is less than 23 millinewtons per meter. The chemical composition of this product adopts an allyl alcohol modified organic silicon bifacial structure surfactant, which combines the extremely low surface tension characteristic of organic silicon with the penetration promoting performance of allyl alcohol compounds.


II. Core Performance Advantages


Product 4100, with its innovative bifacial molecular structure, exhibits the following core advantages in application performance:


Multi-effect integration of wetting, defoaming, and anti-shrinkage. Traditional wetting agents, while reducing the surface tension of the system and improving wetting performance, often inevitably cause foam problems, requiring additional defoaming agents for balance. This product, through the special design of the allyl alcohol modified organic silicon bifacial structure, achieves excellent wetting effects while maintaining non-foaming characteristics, completely solving the industry pain point of "wetting must cause foaming" of traditional additives.


Super wetting ability for difficult-to-wet substrates. The product can significantly reduce the surface tension of water-based systems to below 23 millinewtons per meter, enabling rapid spreading and perfect wetting of various difficult-to-coat substrates such as plastics, metals, high surface energy coatings, and fluorine-containing materials, significantly reducing surface defects such as pinholes, fish eyes, and needle eyes.


Excellent system compatibility and versatility. The product is suitable for various mainstream water-based resin systems such as water-based polyurethane, water-based acrylic, and water-based epoxy, and does not affect the transparency and gloss of the system, meeting the performance requirements of clearcoats and high-gloss coatings.


III. Wide Application Areas


Product 4100, with its multi-functional performance combination, can play a key role in the following application areas:


1. Water-based coating systems. In industrial coatings, wood coatings, architectural coatings, and construction machinery coating systems, the product can significantly improve the wetting and adhesion of coatings to various substrates, optimize leveling, effectively eliminate shrinkage and orange peel phenomena, and be particularly suitable for high shear force applications such as spraying and high-speed rolling processes.


2. Water-based ink systems. In gravure printing, flexographic printing, etc., the product can enhance the spreading of ink on difficult-to-wet substrates such as films and composite papers, ensuring clear printing edges and full color, without printing defects caused by uneven wetting.


3. Synthetic leather release paper wetting treatment. In the production of synthetic leather, the product can be used for release paper wetting treatment, improving the uniform coating of release agents on the paper surface, avoiding poor peeling and fish eye problems caused by uneven substrate surface tension, and ensuring the flatness and stability of the synthetic leather product surface.


4. Usage Suggestions and Recommended Dosage


The recommended dosage of product 4100 is 0.1% to 1.0% of the total formulation. The product can be added directly or incorporated at any stage of the production process. It is recommended to conduct a small-scale trial before use to determine the optimal dosage. Its 100% active content and moderate viscosity characteristics make it easy to disperse in the system and facilitate the operation.


V. Packaging Specifications and Storage Conditions


Product non-foaming defoaming wetting agent 4100 is available in two packaging specifications: a 25-kilogram plastic drum and a 200-kilogram iron drum. The product should be stored in a sealed manner under normal temperature conditions, avoiding direct sunlight and high-temperature environments. Under the above storage conditions and without being opened, the shelf life is 24 months.


VI. Quality Assurance and Industry Application Value


Product non-foaming defoaming wetting agent 4100 has established a strict quality control system during the production process. It conducts full-process testing on key indicators such as product appearance, refractive index, viscosity, and surface tension to ensure consistency and reliability between batches. As the water-based coatings, printing inks, and synthetic leather industries continue to develop towards environmental protection, high-speed, and high-quality directions, the demand for efficient additives with both wetting and defoaming functions is steadily increasing. Product non-foaming defoaming wetting agent 4100, with its innovative dual structure design, low addition amount, and high-efficiency comprehensive performance advantages, is becoming an important additive option in the water-based system processing field, providing strong support for promoting the product quality improvement and process optimization in related industries.
