APPLICATION -

Before application of EP-101 Epoxy 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 clean 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 three 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 aluminum use TC Etch Primer before application of Epoxy 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 12° 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.
