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.

Applications
- 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.
Key properties
- Reduced viscosity vs 100% solids — easier spray application
- Extended pot-life vs solvent-free systems
- Excellent adhesion to blasted steel (Sa 2.5) and power-tool prepared surfaces
- Good film build per coat
- Compatible with polyamide, phenalkamine, and aliphatic amine hardeners
- Proven in hot, humid GCC coastal environments
- Standard bisphenol-A epoxy resin solution grade in xylene
Usage and recommendations
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.
