Features Of Evonik EPODIL 748 Epoxy Reactive Diluent

  1. Low-viscosity mono-functional epoxy reactive diluent for significant viscosity reduction without compromising epoxy functionality.

  2. Enables improved wetting and penetration in fiber-reinforced composites and porous substrates.

  3. Offers balanced reactivity—compatible with standard amine and anhydride curing agents.

  4. Contributes to enhanced flexibility and reduced internal stress in cured epoxy networks.

  5. Free of volatile organic compounds (VOC-free), supporting sustainable formulation requirements.

Typical Applications Of Evonik EPODIL 748 Epoxy Reactive Diluent

  1. Wind turbine blade resins requiring low-viscosity, high-performance infusion systems.

  2. Aerospace composite tooling and structural adhesives demanding controlled rheology and toughness.

  3. Electrical encapsulation and potting compounds where dielectric integrity and thermal stability are critical.

  4. High-solids industrial coatings for corrosion protection on steel and concrete infrastructure.

  5. 3D printing (vat photopolymerization) epoxy-based resins requiring precise flow control and cure fidelity.
