Features Of Dow D.E.H.530 Modified Amine Epoxy Curing Agent

  1. Low-viscosity liquid formulation enabling easy handling and efficient mixing with epoxy resins.

  2. Modified amine chemistry providing improved flexibility and reduced brittleness in cured systems.

  3. Enhanced moisture tolerance compared to conventional aliphatic amines, supporting more robust processing conditions.

  4. Good pot life at ambient temperature (typically 4–6 hours at 25°C), balancing workability and cure speed.

  5. Delivers excellent adhesion to metals, concrete, and composites without mandatory surface priming.

Typical Applications Of Dow D.E.H.530 Modified Amine Epoxy Curing Agent

  1. Industrial flooring and concrete repair mortars requiring rapid turnaround and chemical resistance.

  2. Protective coatings for steel infrastructure, including bridges, pipelines, and marine assets.

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

  4. Composite bonding adhesives for wind turbine blades and transportation components.

  5. High-performance grouts and anchoring systems in construction and civil engineering.
