Description
EP0408.03.30 is a hybrid mixture with an inorganic silsesquioxane at the core and organic epoxycyclohexyl groups attached at the corners of the cage. The EP0408 POSS® is blended with a reactive epoxycyclohexyl diluent for ease of use. EP0408.03.30 can be cured with aromatic, aliphatic amines and photoinitiators. EP3F08.04 provides increased use temperature, excellent water and solvent resistance, and enhanced thermomechanical performance.
