490HOR is a Fast drying, Single component Acrylated polymer based anti corrosive “TRANSFORMER HEAT OIL RESISTANCE’ coating pigmented with Zinc Phosphate as corrosion inhibiting pigment. It protects internal surface of transformer tank from oil heat for maximum 140°C temperature.
It is specially designed to use as tank lining on surface of electrical transformer tanks, however it is also recommended to use on sheet metal in various fabrication Industries, Heavy machineries and can be applied on diverse areas of tank interiors/ exteriors, equipments, pipelines, structural steel 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. This product is suitable for use over phosphate washed steel.
Steel : Abrasive blast clean to a minimum of Sa2½ (ISO 8501-1:2007). Surface defects revealed by the blast cleaning process should be ground, filled, or treated in the appropriate manner. A surface profile of 30-40 microns is recommended.
Primed Surface : Already primed (or wash primed) surface should be dry and free from all contamination and Indoprotect 490HOR should be applied within the overcoating intervals specified in earlier primer/ etch primer TDS. Area of damaged primer or rework etc should be prepared as per specified standards, either by power tool cleaning or other means.
