Heavy Duty Coating
EVACOAT WASH PRIMER KS M 6030 Class 4 wash primer(2K)
- usage
- Pretreatment primer for industrial steel and non-ferrous metals (galvanizing, aluminum, etc.)
This paint is a two-component wash primer manufactured using excellent rust-preventive pigments that do not contain epoxy resins and harmful heavy metals.
It has excellent temporary rust prevention and substrate adhesion, and has good adhesion with the subsequent coating and top coating, so it is a paint suitable for KS M 6030 4 types as a pretreatment primer for general industrial and industrial facilities.

how to use
- Surface treatment
- 1. Completely remove oil, moisture, sand, dust, and other foreign matter from the surface to be coated.
2. Paint the steel immediately after processing.
3. High gloss and smooth galvanized steel sheets (such as deck plates) require a test coat. To increase adhesion, surface treatment with sandpapering is recommended if necessary. - Coating method
- 1. Coating can be done by either brush, air or airless spray coating.
2. Airless spray coating:
- Tip diameter : 0.013"~0.017"
- Injection pressure : 1500~2000 PS.I(105~140㎏/㎠)
- Store the coating equipment after cleaning with an exclusive thinner immediately after use. - Preceding and follow-up coating
- 1. Follow-up coating : Epoxy resin, urethane resin, alkyd resin, fluororesin top coat
- Remarks
- 1. Sufficient performance after last coating is achieved after drying for 7 days at 20℃.
2. For coating areas exposed to the outside, yellowing and chalking may occur in a short period of time due to the effect of sunlight. Upon coating for areas exposed to the outside, be sure to apply top coating.
3. Apply the dry film with the recommended thickness of dried film.
