Phenalkamine hardeners are the preferred curing agent for epoxy coatings applied in the high-humidity coastal environments of the UAE and Saudi Arabia. Derived from cashew nut shell liquid (CNSL) and polyamines, phenalkamines provide exceptional tolerance to moisture during application, blush-free surface films, and outstanding adhesion to damp substrates — making them the industry standard for marine primers, waterproofing systems, and offshore coatings across the Arabian Gulf.

Marine Anti-Corrosion Primers
Primary hardener for marine primers and topcoats on vessels, port structures, and offshore platforms operating in the Arabian Gulf and Red Sea. Phenalkamines cure reliably under the humid conditions typical of UAE coastal operations.
Waterproofing & Damp Substrate Bonding
Exceptional adhesion to damp concrete and masonry — critical for waterproofing membranes, basement coatings, and infrastructure protection in UAE and Saudi Arabia where substrate moisture control is challenging.
Tank Linings & Immersion Coatings
Preferred hardener for potable water tank linings, chemical storage tank interiors, and sewage treatment plant coatings across GCC industrial facilities.
Protective Topcoats on Steel
Used in two-component epoxy finish coatings on structural steel in coastal UAE environments — resists amine blushing under high relative humidity (> 85% RH) common in Dubai and Abu Dhabi summers.
NEOM & Saudi Vision 2030 Projects
Phenalkamine-based systems meet the demanding environmental and durability specifications for mega-project coatings in Saudi Arabia — bridges, infrastructure, marine facilities, and industrial structures.
Pipe Coating & Pipeline Protection
Used in fusion-bonded and liquid-applied epoxy pipe coatings for GCC oil, gas, and water distribution pipelines requiring moisture-tolerant cure in field conditions.
Typical mix ratio: 60–100 g per 100 g epoxy resin (EEW 190) — varies by specific phenalkamine grade. Always calculate from actual AHEW on the batch COA and the EEW of the epoxy batch. In GCC summer conditions (45°C+), pot-life is reduced by 40–60% from the 25°C datasheet values — mix smaller batches and work in early morning hours. Can be used with RAYPOXY YR-128 liquid epoxy resin. Contact Raykem technical team for formulation guidance specific to your application and substrate.
Store in sealed original containers at 5–30°C in a cool, ventilated area away from direct sunlight. Shelf life: 12 months from date of manufacture. Keep containers sealed when not in use — phenalkamines react with CO₂ and moisture on prolonged exposure.
