In the field of polymer materials, resin modification is a key method to enhance material properties. IOTA 8866 Diol Hydroxyl End-capped Silicones, a highly reactive organosilicon prepolymer, significantly improves the wear resistance, feel, and anti-soiling properties of polymer materials, making it a multifunctional additive for material modification.

Product Features:
IOTA 8866 is a colorless to pale yellow transparent liquid with an average molecular weight of 4250. It has a viscosity range of 800-1800 cst (25°C) and a hydroxyl content of 0.8%. Its high reactivity and low surface tension enable excellent compatibility with various polymer materials, improving the overall performance of the materials.

Application Fields and Problems Solved:

• Polyurethane Materials:
  IOTA 8866 reacts with isocyanates to form -NCO-end-capped prepolymers, significantly improving the wear resistance and anti-adhesion properties of polyurethane materials, addressing issues such as wear and adhesion in traditional polyurethane materials.

• Polyester Materials:
  Adding IOTA 8866 to polyester materials imparts a smooth feel and improves anti-soiling properties, solving the issues of rough texture and easy contamination in conventional polyester materials.

• Polyurethane Acrylate Resins:
  IOTA 8866 interacts efficiently with polyurethane acrylate resins, enhancing anti-graffiti and leveling properties, solving issues of graffiti and uneven surfaces in traditional resins.

Usage Instructions:
For polyurethane materials, it is recommended to co-polymerize with isocyanates at 85°C. For polyester materials and polyurethane acrylate resins, it can be directly added to the main resin and evenly dispersed.

Packaging and Storage:
IOTA 8866 is available in 125ml brown glass bottles, 25KG plastic drums, or 200KG plastic drums. It has a shelf life of 24 months when stored in unopened conditions at room temperature.
