Non-reactive diluents

Epoxy Modifiers (Non-Reactive Diluents)

Epoxy modifiers, often referred to as non-reactive diluents, are specialized additives used in epoxy resin formulations to modify the properties of epoxy materials. Unlike reactive diluents, which chemically crosslink with epoxy resins during curing, non-reactive diluents do not participate in the curing reaction. Instead, they are added to epoxy formulations to achieve specific performance enhancements or to adjust viscosity.


  • Deco (Decoration): Epoxy modifiers are used in decorative applications, enhancing the aesthetics and durability of decorative coatings and finishes.
  • Industrial Coatings: These modifiers play a crucial role in industrial coatings, providing improved adhesion, resistance, and durability for industrial equipment and surfaces.
  • Marine & Protective Coatings: In the marine and protective coatings industry, epoxy modifiers contribute to water resistance, corrosion protection, and durability in harsh environments.
  • Floor Coatings: Epoxy modifiers are commonly used in floor coatings, offering durability, chemical resistance, and aesthetics for commercial and industrial flooring.
  • Building & Construction: In construction projects, epoxy modifiers enhance the performance and longevity of building materials, such as concrete, adhesives, and coatings.
  • Energy: These modifiers may be employed in the energy sector for various purposes, including electrical insulation or component fabrication in demanding energy applications.
  • Automotive: Epoxy modifiers find applications in the automotive industry, contributing to high-performance coatings, adhesives, and components.
  • Adhesives & Sealants: Epoxy modifiers are used in adhesives and sealants to improve bonding capabilities and overall performance in various bonding applications across industries.

Unique Properties

  • Viscosity Control: They can significantly reduce the viscosity of epoxy formulations, making them easier to handle and apply.
  • Improved Flow: Non-reactive diluents improve the flow and leveling characteristics of epoxy materials, resulting in smoother coatings.
  • Cure Time Adjustment: They can be used to control the curing time of epoxy systems, allowing for longer or shorter working times.
  • Reduced Shrinkage: By diluting the epoxy resin, non-reactive diluents can reduce shrinkage during curing, minimizing the potential for cracks or voids.
  • Enhanced Adhesion: Some modifiers are designed to improve the adhesion of epoxy formulations to various substrates.
  • Chemical Compatibility: They are generally compatible with epoxy resins and do not negatively impact the chemical resistance or final properties of the cured epoxy.
  • Sea Water Resistance: It offers exceptional resistance to sea water, providing robust corrosion protection without compromising the material's integrity or performance.

Alternative for

The choice of using epoxy modifiers (non-reactive diluents) depends on specific application requirements, such as viscosity control, cure time adjustment, and adhesion improvement. Alternatives may include different types of diluents, extenders, or viscosity-reducing additives, depending on the desired characteristics and cost considerations. The selection is influenced by factors such as compatibility with epoxy resins, regulatory compliance, and the desired performance enhancements. Epoxy modifiers are preferred when their unique combination of properties aligns with the application's needs, particularly in industries where precise control over viscosity, cure time, and adhesion is essential.
