In the process of the continuous development of water-based coatings, adhesives and polymer materials towards high-performance and environmentally friendly directions, functional additives with both reactive properties and excellent silicone characteristics are becoming key elements for achieving breakthroughs in material performance. Our company's product, modified hydroxypropyl silicone oil 2040, as a linear organic functional poly siloxane emulsion specifically designed for water-based systems, demonstrates significant industrial application value in enhancing the low-temperature flexibility and toughness of polymers, improving processing fluidity, providing isolation and anti-staining and anti-daubing functions, etc. It offers an efficient modification solution for the development of water-based coatings and polymer materials.


I. Core Structure and Physical Properties of the Product


Modified hydroxypropyl silicone oil 2040 is a linear organic functional poly siloxane emulsion. It appears as a milky liquid with an active component of no less than 45%. Due to the presence of terminal hydroxyl groups at the molecule ends, this product can be used as an active component in polymers and is easily soluble in water-based systems. This design enables it to stably introduce into the polymer main chain through chemical bonds, providing an ideal organic silicone modification pathway for water-based systems. The high content of active components means that the desired modification effect can be achieved with a lower addition amount, offering good cost-effectiveness.


II. Core Performance Advantages


Modified hydroxypropyl silicone oil 2040 demonstrates the following core performance advantages in polymer modification:


First, it improves the low-temperature flexibility and toughness of polymers. After adding this product, polymers can maintain good elasticity at low temperatures and are less prone to cracking, effectively expanding the material's operating temperature range.


Second, it provides excellent processing fluidity for polymers. During polymer molding, the improved material fluidity enables more uniform filling of the mold, reducing the occurrence of bubbles and defects.


Third, by utilizing the automatic surface migration effect of silicone, the polymer exhibits good isolation and anti-staining properties. The silicone chain segments accumulate on the material surface, forming a low surface energy protective layer, providing the substrate with long-lasting anti-staining and anti-fouling effects. When used to manufacture water-based anti-daubing coatings, it has an additional peel-off effect, making daubing easy to clean.


Fourth, it enhances the temperature resistance and wear resistance of polymers, extending the service life of products in high-temperature or frictional conditions.


III. Application Areas and Usage Methods


Modified hydroxypropyl silicone oil 2040, with its multi-functional characteristics, plays an important role in the following key application areas. Specifically:


1. Water-based anti-daubing coatings. This product can be used to manufacture water-based anti-daubing coatings, providing excellent ink-resistant performance and anti-daubing effects, and having a peel-off property, making surface maintenance and cleaning convenient. It can be diluted with water and is easy to operate.


2. Release agents and demolding agents. As an efficient water-based release agent or demolding agent, it is used in water-based coatings and other systems. The recommended addition amount is typically 6% to 20%.


3. Polymer modification. Adding a small amount (depending on the required performance, the addition amount is usually between 6% and 30%), it can significantly improve the flexibility, fluidity, surface smoothness and wear resistance of water-based coatings, adhesives, etc. It is suitable for enhancing the comprehensive performance of polyurethane, acrylic resin, epoxy resin and other water-based polymers.


4. Packaging, storage and safety


Modified hydroxypropyl silicone oil 2040 is available in various packaging specifications, including 1 kilogram, 5 kilograms, 25 kilograms, and 200 kilograms per barrel. It should be stored in a sealed environment at room temperature. The storage period is 12 months. It is important to note that contact with tin (such as metal containers) will shorten the stability of storage. This product is non-hazardous and should be stored and transported in accordance with general chemicals.


IV. Quality Assurance and Application Value


Product modified hydroxypropyl silicone oil 2040 has established a strict quality control system during the production process. It conducts full-process testing on key indicators such as product appearance and active ingredient content to ensure consistency and reliability between batches. As the water-based coatings, adhesives, and polymer materials industry continues to develop towards environmental protection and functionalization, the demand for water-based functional additives with both reactive properties and excellent silicone characteristics is steadily increasing. This product, thanks to its terminal hydroxyl groups providing reactive properties, high active ingredient content leading to efficient modification capabilities, and wide compatibility with various systems, is becoming an important additive option in water-based anti-graffiti coatings, release and demolding, and polymer performance improvement fields. It provides strong raw material support for promoting product innovation and green upgrading in related industries.
