EP0408 Epoxycyclohexyl POSS Ca

EP0408 is a hybrid molecule with an inorganic silsesquioxane at the core and organic epoxycyclohexyl groups attached at the corners of the cage. EP0408 can be cured with aromatic, aliphatic amines and photo initiators. EP0408 and its variations can provide increased use temperature, excellent water and solvent resistance and enhanced thermomechanical performance.

EP0408 is available in several variations and dilutions, depending on the need. These include, but are not limited to:
EP3F08.01 (70 wt. % EP0408 with 30 wt. % PGMEA)
EP3F08.02 (70 wt. % EP0408 with 30 wt. % Cyclopentanone)
EP3F08.04 (70 wt. % EP0408 with 30 wt. % Cycloaliphatic Epoxy Diluent)
