Description
EP0409.07.30 Nanosilica Dispersion is two reinforcing agents in one. EP0409 is a hybrid, 1.5nm molecule with an inorganic silsesquioxane at the core, and organic glycidyl groups attached at the corners of the cage, which acts as a multifunctional crosslinker. 30 weight percent of 20nm nanosilica is completely dispersed into the EP0409, creating a clear, colorless liquid which is easily blended into other sytems. EP0409 serves as a high temperature reactive diluent in both aromatic and aliphatic epoxy resin affording 40%-70% viscosity reductions. EP0409 can be formulated with aliphatic amines to provide, low viscosity, room temperature cure and high HDT composite resins and adhesives. The “POSS®-HDT-Effect” is recognized by increased rubbery plateau modulus. POSS® molecules also have robust resistance to environmental degradation such as, moisture, oxidation, corrosion, and various types of radiation. The 30% silica improves the reinforcement even more. EP0409.07.30 Nanosilica Dispersion is available in 100g and 1 kg quantities.
