Epoxy Systems for Industrial Composites

The industrial market covers a wide range of opportunities for composite application. Composites can simply act as cost-competitive, weight-saving alternatives to traditional materials. But they can also form next-generation filament-wound pressure vessels for fuel transport, or work in robotic applications that require high precision, lightweight, fast-moving apertures. Composites can excel in industrial applications because of their:

Low weight
High strength-to-weight ratios
Suitability for high dynamic loads
Excellent fatigue properties
Precision shapability
Dimensional stability
Corrosion and environmental resistance
