CAS No: 25068-38-6 · HS Code: 3907.30
Solvented epoxy resin — Bisphenol-A liquid epoxy resin supplied at 75% or 80% active solids in xylene — is the standard raw material for solvent-borne two-component epoxy primers and topcoats used in heavy-duty anti-corrosion coating systems. The xylene dilution reduces handling viscosity and extends pot-life, enabling application by brush, roller, and conventional spray on structural steel, pipelines, and marine structures across UAE and Saudi Arabia.

Two-Component Anti-Corrosion Primers
Standard resin component in solvent-borne epoxy anti-corrosion primers for structural steel, bridges, storage tanks, and industrial structures across UAE and Saudi Arabia. Used with RAYCURE 915, 915X75, or phenalkamine hardeners.
Pipeline & Tank Coating Systems
Used in solvent-borne epoxy coating systems for above-ground and buried steel pipelines, storage tanks, and pressure vessels in GCC oil, gas, and water infrastructure projects.
Marine & Offshore Coatings
Component in marine epoxy primers and stripe coats for vessels, offshore platforms, and port structures operating in the Arabian Gulf and Red Sea corrosive marine environment.
Maintenance & Repair Coatings
Ideal for large-area maintenance painting of existing steel structures where a solvent-borne system is required for penetration of aged surfaces and surface-tolerant performance.
Industrial Maintenance Programmes
Part of multi-coat anti-corrosion systems (primer + intermediate + topcoat) for UAE petrochemical plants, power stations, and industrial facilities.
Use RAYCURE 915X75 (polyamide in xylene) as the paired hardener for a fully compatible two-component system. Alternatively use RAYCURE 915 (100% polyamide) diluted in xylene. Mix ratio based on EEW of resin and AHEW of hardener — calculate from actual COA values. Flash point of xylene (27–32°C) means the mixed system requires flammable liquid storage and handling. In GCC summer heat, pot-life will be reduced — mix smaller batches. For SASO VOC compliance in Saudi Arabia, consider switching to RAYPOXY YR-128 (100% solids) with RAYCURE RD12 reactive diluent for a low-VOC alternative.
Store in sealed containers in a dedicated flammable liquid storage area at 5–35°C, away from heat and ignition sources. Earthing and bonding required during transfer. Shelf life: 12 months. FIFO stock rotation essential.
