RAYCURE RD12 — Reactive Diluent for Epoxy Systems

RAYCURE RD12 is a mono glycidyl ether of C12-C14 fatty alcohol used as a reactive diluent for high-viscosity epoxy resins.

It reduces viscosity while maintaining reactive functionality, enabling high-solids or solvent-free coating formulations with improved flexibility, substrate wetting, and mechanical stability — ideal for structural steel and concrete flooring applications across the GCC.

Applications

  • Reactive diluent used in combination with liquid or solid epoxy resin solutions to reduce viscosity for spray application
  • Enables high-solids and solvent-free coating compositions meeting SASO VOC limits for Saudi Arabia
  • Ideal for structural steel coatings, concrete flooring, and all epoxy coating types across UAE industrial facilities
  • Self-levelling systems for concrete screeds with high mechanical stability
  • Airless spray applications on large steel structures — reduced viscosity without solvent addition
  • Two-component solvent-free floor coatings for food processing, pharmaceutical, and industrial facilities in GCC

Key properties

  • Very low viscosity (5–10 mPa·s) enables significant epoxy viscosity reduction
  • Solvent-free — contributes no VOC to the formulation
  • Reactive — participates in the cure reaction (not a plasticiser)
  • Good flexibility contribution to cured film
  • Excellent substrate wetting on concrete and steel
  • Suitable for one-component airless spray
  • Low hydrolysable chlorine (< 0.1%)
  • Compatible with RAYPOXY YR-128 and other BPA epoxy resins

Usage and recommendations

Typical use level: 5–15% on total epoxy weight. Higher loading reduces mechanical properties — evaluate for your specific formulation. Compatible with RAYPOXY YR-128. Can be blended with epoxy resin before adding hardener. Used with RAYCURE series hardeners for solvent-free floor coatings. For GCC climate applications, combine with a phenalkamine hardener for humidity-tolerant cure.
