Brand: Kaneka Aerospace LLC
SKU: KANEKA GR6820

Main features

Low-Viscosity Winding and Infusion
Extended 15-Hour Processing Window
High-Temperature Chemical Resistance

Product Description

Kaneka GR6820 is a low-viscosity epoxy composite resin grade for winding and infusion. Initial viscosity is 390 mPa*s, while the 15-hour working life before viscosity doubles provides an extended processing window for composite fabrication. The cure uses a step-cure process. Cured-system data include a 181 deg C glass transition temperature, 139 MPa flexural strength, and 3.1 GPa flexural modulus. The grade combines high-temperature capability with chemical resistance for winding and infusion applications. This product is the epoxy resin grade only; a curing agent is not included.

Key features

Low initial viscosity: Initial viscosity is 390 mPa*s for winding and infusion processing.
Extended working window: Working life is 15 hours before viscosity doubles.
High-temperature resistance: Cured-system Tg is 181 deg C with chemical-resistant application scope.

Applications

Composite winding and infusion for high-temperature, chemically resistant applications.
