Two component Surface Tolerant (Polyamine cured) coating pigmented with aluminium to provide better barrier protection. It’s a high solids, abrasion resistant coating, which can be applied directly to mechanically prepared shop primer or suitably prepared bare steel.
690UHS mastic is recommended as primer, intermediate coat or as topcoat provides long lasting protection in environments with high corrosivity. It can be used as single coat system in atmospheric and immersed environments. Recommended for Steel Structures, Mining Equipments, Pipelines, Storage Tanks etc including hand prepared rusty steel, hydroblasted steel, and a wide range of intact, aged coatings in Infrastructure projects, Bridges, Refinaries Pipelines, Chemical Plants, Steel Plants, Cement Plants, Petrochemicals Plants etc.

All surfaces to be coated should be clean, absolutely dry and oil or moisture free before painting application. Oil and grease should be removed by solvent cleaning.
Repair Cases : Corroded areas should be power tool cleaned to St3 or blast cleaned to Sa2 or better. Existing system should be dry and free from loose paint, salt, grease and other contaminants prior to overcoating.
New steel : Abrasive blasting to Sa 2½ (ISO 8501-1:2007). For temporary protection, if required, use a suitable shopprimer. All damage of shopprimer and contamination from storage and fabrication should be thoroughly cleaned prior to final painting.
Maintenance : Remove oil and grease etc. thoroughly with suitable detergent. Remove salts and other contaminants by high pressure fresh water cleaning. Clean damaged areas thoroughly by power tool cleaning to St 3 (ISO 8501-1:2007) (minor areas) or by abrasive blasting to min. Sa 2, preferably to Sa 2½ (ISO 8501-1:2007). Improved surface preparation will improve the performance of the product.
Aged Surface : Indopoxy 690UHS is suitable for overcoating a limited range of intact, tightly adherent aged coatings. Loose or flaking coatings should be removed back to a firm edge. Glossy finishes require light abrasion by emery paper or power tool to provide a physical key.
