Novel Alternative in High Performance Clear Coats: Molecular Composites Utilizing Arylsilane Aramids
Polymers and High Performance Materials
Novel arylsilane diacids were synthesized and polymerized to yield rigid yet soluble aramids. The aramids were incorporated into an elastomeric epoxy/Jeffamine(R) coating to yield soluble polymers which are easily cast into clear films with exceptional physical properties. For instance, when films are cast from the elastomeric epoxy control and compared to silicon containing composites, the composites exhibited tensile strenght increases of more than six fold, hardness increases from 2H to 8H, and although elongation decreases of 50 fold were noted, film adhesion was excellent as no failures occurred even under a direct impact of 18.1 + J.
