Indothane 280 is a Two component isocynate cured fast drying anti corrosive general industrial primer containing Zinc Phosphate as corrosion inhibiting pigments.
It is recommended as primer coat on M.S. surface in diverse areas of heavy machinery, agriculture implements, MS, CR and structural steel etc. It is an ideal primer where fast turnaround of equipment is desired and is recommended for material which are exposed to medium corrosive environement. It can be overcoated within one hour of application, hence making it ideal to be use in variety of applications.

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.
Stainless steel : To be abrasive blast cleaned to a uniform, sharp, dense profile (ISO Comparator Medium (G), corresponding to Rz minimum 50 micron. Any salts, grease, oil, etc. to be removed before abrasive blasting is commenced.
