Features Of Shikoku C11Z Epoxy Resin

  1. High reactivity with standard amine and anhydride curing agents, enabling rapid gelation and short cycle times.

  2. Excellent adhesion to metals, composites, and treated plastics without requiring primers.

  3. Low viscosity (450–650 mPa·s at 25°C) for easy handling, degassing, and deep impregnation into fiber reinforcements.

  4. Superior electrical insulation properties with high dielectric strength (>18 kV/mm) and volume resistivity (>1×10¹⁴ Ω·cm).

  5. Good thermal stability with glass transition temperature (Tg) of 120–130°C after full cure with DDS.

Typical Applications Of Shikoku C11Z Epoxy Resin

  1. Electrical encapsulation and potting of power modules, sensors, and high-voltage components.

  2. Matrix resin for filament-wound pressure vessels and structural composite parts in aerospace and energy sectors.

  3. Insulating varnish and impregnating resin for high-efficiency motors and generators.

  4. Adhesive formulation for bonding dissimilar substrates in automotive electronics and battery modules.

  5. Base resin for high-performance printed circuit board (PCB) laminates and prepregs.
