Applications
- Anti-Skinning in Alkyd Paint Cans — Primary application — added at 0.1–0.3% to alkyd decorative and industrial paints before canning to prevent surface skin formation during 12–24 month storage in UAE and Saudi Arabia supply chain conditions, where elevated temperatures (30–55°C in distribution) accelerate oxidative drying.
- Clear Varnishes & Wood Finishes — Protects long-oil alkyd and oil-modified varnishes from skinning during storage — skin in varnish causes lumps that are visible in the applied film.
- Industrial Alkyd Primers & Maintenance Paints — Added to alkyd anti-corrosion primers and maintenance paints to ensure consistent performance and no skinning on the paint surface in cans stored at UAE and Saudi Arabia industrial facility warehouses.
- Oil-Modified Urethane Finishes — Prevents skin formation in oil-modified urethane floor finishes and oil-alkyd coatings — the drier system in these products is highly prone to surface oxidation without adequate MEKO protection.
Key properties
- Highly effective cobalt and manganese drier deactivator in sealed can
- Rapid volatilisation on can opening — restores full drying performance
- Does not permanently deactivate driers — no impact on dry time after opening
- Effective at very low addition levels (0.1–0.3%)
- No significant effect on paint film properties or final dried film
- Compatible with all standard alkyd binder systems
- Flash point 34°C — handle as flammable liquid
- Purity ≥ 99% — consistent performance
Packaging
- 20 kg Jerry Cans
- 200 kg Steel Drums (lacquer-lined)
- Custom packaging on request
Storage and shelf life
Store in sealed, lacquer-lined steel drums at 5–30°C in a dedicated flammable liquid store, away from heat and ignition sources. Flash point 34°C — classified as flammable liquid (Class 3). Shelf life: 24 months. Earthing and bonding required during transfer operations.
