Diol hydroxyl single-end silicone oil IOTA 2176, launched by the brand IOTA, is a high-performance organosilicon compound. It is a polydimethylsiloxane-polyether system with hydroxymethyl as the terminal functional group, available in both water-based and solvent-based types, making it suitable for diverse application scenarios. The product appears as a light yellow viscous liquid, with an active ingredient content of up to 99.9% and a molecular weight precisely controlled at approximately 3200. Its high purity and stable molecular structure lay a solid foundation for its excellent performance.
In terms of dosage, the product offers great flexibility: adding only 0.2-1% can endow the product with a long-lasting smooth feel; a dosage of 2-6% can achieve effective antifouling performance, reducing the adhesion of stains on the substrate surface; when used for resin modification, a dosage of 1-6% can realize targeted optimization of resin properties, facilitating product quality upgrading.
Its core competitiveness stems from excellent compatibility and reaction activity—it can perfectly match various polyurethane and amino systems, and the terminal hydroxymethyl groups can undergo efficient cross-linking reactions with resin systems, directionally introducing silicone components into the surface and interior of the resin. This feature can significantly improve the comprehensive properties of the resin, including weather resistance stability, stain resistance and easy cleanability, as well as low-temperature toughness, providing reliable performance support for end products in fields such as coatings, adhesives, and composite materials.
