EP0409 – Glycidyl POSS cage mixture

Description

EP0409 is a hybrid molecule with an inorganic silsesquioxane at the core and organic glycidyl groups attached at the corners of the cage. EP0409 serves as a high temperature reactive diluent in both aromatic and aliphatic epoxy resin and will increase rubbery plateau modulus. POSS molecules also have robust resistance to environmental degradation such as moisture, oxidation, corrosion and UV radiation. EP0409 is also excellent at dispersing silica particles.

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