Features Of HDX-50E Curing Agent

  1. Fast-reacting aliphatic amine-based curing agent for ambient and low-temperature cure profiles.

  2. Excellent compatibility with standard epoxy resins, enabling uniform crosslinking without phase separation.

  3. Low viscosity (250–350 mPa·s at 25°C) ensures easy metering, mixing, and air-release during processing.

  4. Low volatility and non-crystallizing formulation enhances shelf stability and handling safety.

  5. Delivers high glass transition temperature (Tg > 85°C) and superior chemical resistance in cured networks.

Typical Applications Of HDX-50E Curing Agent

  1. Structural adhesives for automotive and aerospace bonding assemblies.

  2. Electrical encapsulants and potting compounds requiring rapid throughput and thermal reliability.

  3. High-performance coating systems for industrial flooring and protective linings.

  4. Composite matrix resins in wind blade and marine applications.

  5. Repair mortars and grouts where fast strength development is critical.
