AM0265 – AminopropylIsobutyl POSS

Description

AM0265 is a hybrid molecule with an inorganic silsesquioxane at the core, organic isobutyl groups attached to seven corners of the cage and an aminopropyl group attached to the eighth. It has been used to increase spacing between chains in polyimides to reduce color. It is also effective at improving weather-ability of polymers and coatings by reducing water sorption.
