HC0313.31 – Cyclohexylethylepoxy PEG POSS



HC0313.31 is a hybrid molecule with an inorganic silsesquioxane at the core and organic cyclohexylethylepoxy and PEG  groups and attached at the corners of the cage. HC0313.31 serves as a high temperature reactive diluent in both aromatic and aliphatic epoxy and urethane resin. POSS molecules also have robust resistance to environmental degradation such as moisture, oxidation, corrosion and UV radiation.

Applications: additive for high hardness optical coatings.  Rheological diluent for highly filled resins and composites. Dispersant for CNTs and related carbons.
