As SASO VOC regulations tighten for architectural and industrial coatings in Saudi Arabia, and as UAE green building codes (Estidama, Dubai Municipality) drive demand for low-emission products, PADA hardeners enable high-performance epoxy coatings with dramatically reduced volatile organic compound content compared to solvent-borne alternatives.

Applications
- SASO-Compliant Architectural Coatings Saudi Arabia — Enables waterborne epoxy primers and topcoats meeting SASO VOC limits for architectural coatings in Saudi Arabia. Critical for Vision 2030 residential and commercial projects specifying low-emission coating systems.
- UAE Green Building Coatings — Meets Estidama Pearl rating and Dubai Municipality low-VOC coating requirements for commercial, healthcare, and educational buildings across the UAE.
- Flooring for Food-Processing Areas — Used in water-based epoxy floor coatings for food processing plants, commercial kitchens, and pharmaceutical facilities where low odour and low VOC during application are mandatory.
- Primer Coats on Concrete & Steel — Water-dispersible epoxy primers using PADA hardeners provide excellent adhesion to concrete and steel with minimal VOC — suitable for enclosed spaces and buildings with occupants present.
- Decorative Interior Coatings — Low-odour, water-cleanable two-component epoxy systems for interior walls, floors, and surfaces in hotels, hospitals, schools, and offices across UAE and Saudi Arabia.
Key properties
- Water-dispersible — enables waterborne two-component epoxy systems
- Low VOC — compliant with SASO and UAE green building requirements
- Low odour during application — suitable for occupied spaces
- Good film formation and adhesion to concrete and steel
- Easy water clean-up of equipment
- Good flexibility in cured film
- Moderate chemical resistance (lower than solvent-borne systems)
- Environmentally preferable raw material profile
Usage and recommendations
Waterborne systems require attention to application temperature and humidity. Apply between 10–35°C with relative humidity below 80%. Do not apply when substrate temperature is below dew point. VOC content of final formulation depends on all components — calculate total VOC including co-solvents, neutralising agents, and coalescing agents. Contact Raykem for waterborne formulation guidance specific to SASO compliance.

Storage and shelf life
Store at 5–30°C. Do not freeze — freezing permanently damages the dispersion. Keep sealed. Shelf life: 12 months from manufacture.
