Our company's product, carbon hydroxyl silicone oil 2110, as a compound of polydimethylsiloxane with a hydroxymethyl end group, demonstrates significant industrial application value in various polyurethane and amino resin systems due to its high-purity active components and efficient cross-linking reaction characteristics with resin systems. It provides precise modification solutions for the performance upgrade of coatings and resin materials.


I. Core Physical and Chemical Properties of the Product


Product carbon hydroxyl silicone oil 2110 is a colorless viscous liquid with an active component content greater than 99% and a molecular weight of approximately 1000. This product has a hydroxymethyl end group as its functional group and belongs to reactive polydimethylsiloxane compounds. It is suitable for solvent-based resin systems. Similar to other carbon hydroxyl silicone oil products, this product has good compatibility in various polyurethane and amino systems and can undergo cross-linking reactions with the active groups of the resin system. The high content of active components ensures efficient utilization in the formulation and avoids interference from inert impurities on the cross-linking reaction and final coating performance.


II. Core Reaction Characteristics and Performance Advantages


The application value of product carbon hydroxyl silicone oil 2110 is rooted in its hydroxymethyl end group and the cross-linking reaction mechanism with the resin system. In polyurethane and amino resin systems, the hydroxymethyl end group of this product can undergo a chemical reaction with isocyanate groups or active groups of amino resins, precisely introducing the organosilicon component into the resin network structure, especially forming an enriched layer on the coating surface.


In terms of performance, this product significantly improves the performance of resins from multiple dimensions. Firstly, it significantly enhances weather resistance, as the organosilicon segments have excellent anti-ultraviolet and anti-oxidation capabilities, which can significantly extend the service life of outdoor coatings and effectively avoid problems such as loss of gloss, flaking, and cracking; secondly, it optimizes the lasting feel, giving the resin surface a smooth and comfortable touch, with a stable effect; thirdly, it improves the resistance to staining, with the modified coating surface being dense and smooth, not easily adsorbing dust and oil stains, and having outstanding self-cleaning effects; fourthly, it significantly improves the resistance to low temperatures, effectively improving the low-temperature toughness of the resin and expanding the application temperature range of the product.
