TP Epoxy Primer MIO is designed for use on steel surfaces for offering superior performance in highly corrosive chemical environment. The base component contains epoxy groups which reacts with amine hardeners based on polyamides Hardener to get tough, irreversible Thermoset film at an ambient or elevated temperature. To get more anticorrosive properties zinc chrome or zinc phosphate is in corporate in base. It can be over coated with Epoxy, Chloro rubber paint and PU topcoats.
Range of Application :
Epoxy Primer is undercoat for Polyurethane, Epoxy and Rubber paints, for various Fertilizer Industries, Refineries, Chemical Plants, Food & Pharmaceutical Industries, Storage Tanks, Pipelines and Structural Steel work. This system is also useful for maintenance coatings. Resistance to Oils, Alcohols, Fats, Solvents and Water gives wide range of application in chemical plants. Good electrical properties give application in panel work.

Application:
Before application of Epoxy MIO primer, do all necessary pretreatment of the job. For M. S. surface, remove all grease, oil and other contamination by using proper degreasing chemical. Blast cleans the surface for heavy rusting or remove with de-rusting chemicals to clean the surface. The surface should be clean and dry before application.
Stir base thoroughly and then mix four parts base and one part hardener by volume to uniform consistency. Give 30 minutes stabilization period to the mix. And then again stir before application.
For brushing if viscosity is higher than 60-80 sec then only add Epoxy thinner to get proper viscosity. It helps to get proper DFT. Use 10 to 15 % Epoxy thinner for conventional spray. For galvanized iron and aluminium use TC Etch Primer before application of Epoxy MIO Primer. Mix the quantity perfect in ratio. Do not mix excess material, as the pot life of mix is 4 hours only. Do not apply when temperature falls below 120 C or relative humidity rises above 90% or during rain, fog or mist. Brushes and spray equipments should be cleaned properly after application; using Epoxy Thinner otherwise equipment is liable to be damaged.
