Features Of YD-115 Epoxy Resin

  1. High purity bisphenol-A based liquid epoxy resin with consistent epoxide equivalent weight (EEW).

  2. Excellent adhesion to metals, composites, and cured thermosets without requiring surface priming.

  3. Low viscosity (< 12,000 cP at 25°C) enabling easy processing via casting, impregnation, and vacuum infusion.

  4. Good thermal stability and low chloride content (< 500 ppm), supporting high-reliability electrical encapsulation.

  5. Compatible with standard amine, anhydride, and catalytic curing agents for flexible formulation design.

Typical Applications Of YD-115 Epoxy Resin

  1. Electrical insulation and potting of transformers, reactors, and medium-voltage switchgear.

  2. Structural adhesive formulations for aerospace composite bonding and automotive metal-to-composite joints.

  3. Matrix resin in filament-wound pressure vessels and pultruded profiles for industrial infrastructure.

  4. Encapsulation of power electronics modules, including IGBTs and SiC-based devices.

  5. High-performance coating base for corrosion-resistant linings in chemical process equipment.
