Application:
Before applying primer remove oil & grease, oil, & other contaminants by using proper degreasing & de-rusting chemicals, if heavy rust is present blast clean the surface. After drying cleaning the surface; stir well the part 1 thoroughly. Weigh out the components in the recommended proportion (1: 1.5 by weight) and slowly add the part 2 with constant stirring preferably with a mechanical stirrer. Continue stirring till the powder is thoroughly dispersed. Filter the mixture through a 60 to 80 mesh sieve or nylon filter cloth. Allow the mix to mature for 15-20 minutes. Apply by conventional spray or airless spray overcoat after 16-18 hours. This is a moisture-cured system & may be applied at high humidity.
