Features Of Huntsman Epoxy Modified Amine Curing Agent Aradur 2973

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

  2. Fast-reacting modified amine chemistry delivering rapid gel time and early strength development at ambient temperatures.

  3. Excellent adhesion to damp or marginally contaminated concrete and steel substrates.

  4. Reduced exotherm compared to conventional aliphatic amines, supporting thicker-section castings and minimizing thermal stress.

  5. Good chemical resistance post-cure, particularly against alkalis, solvents, and mild acids.

Typical Applications Of Huntsman Epoxy Modified Amine Curing Agent Aradur 2973

  1. Industrial flooring systems requiring rapid return-to-service in warehouses and manufacturing facilities.

  2. Concrete repair mortars and grouts for infrastructure rehabilitation projects.

  3. Adhesives and structural bonding agents for metal-to-metal and metal-to-concrete assemblies.

  4. Electrical encapsulation and potting compounds where controlled reactivity and low shrinkage are critical.

  5. Marine and offshore protective coatings for splash zone and submerged steel structures.
