In the coatings industry, resin modification is an essential method to enhance coating performance. IOTA 8866 Diol Hydroxyl End-capped Silicones, a highly reactive organosilicon prepolymer, significantly improves the wear resistance, anti-soiling properties, and leveling of coatings, making it an innovative solution in coating formulations.

Product Features:
IOTA 8866 is a colorless to pale yellow transparent liquid with an average molecular weight of 4250. Its viscosity ranges from 800-1800 cst (25°C), and it has a hydroxyl content of 0.8%. The low surface tension and high reactivity allow excellent compatibility with resins in coatings, enhancing overall coating performance.

Application Fields and Problems Solved:

• Two-component PU Baking Paint:
  IOTA 8866 disperses evenly with the main resin, significantly enhancing the wear resistance and anti-soiling properties, solving issues of wear and contamination in traditional PU baking paints.

• Amino Baking Paint:
  Adding IOTA 8866 to amino baking paints improves leveling and gloss, resolving issues of uneven surfaces and poor gloss in traditional amino baking paints.

• Water-based Coatings:
  IOTA 8866 efficiently interacts with water-based resins, enhancing anti-adhesion and anti-graffiti properties, addressing the problems of adhesion and graffiti in traditional water-based coatings.

Usage Instructions:
For two-component PU and amino baking paints, IOTA 8866 can be directly added to the main resin and evenly dispersed. For water-based coatings, it can be co-polymerized with resins.

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.
