POSS Coating Additives: Epoxy and Acrylic Tool Kits
Joe Lichtenhan, Hybrid Plastics Inc.
Abstract:POSS additives provide a simple to use tool-kit that that require only small loading levels to favorably improve traditional formulations. At only 1.5 nm in diameter, POSS cages provide a tremendous amount of surface area and volume control when incorporated into formulations. POSS additives also are used as compatiblizing tie-layers in coating stacks, and to impart scratch resistance, and omniphobic properties in optical coatings. A mechanistic discussion will be provided.
