Heavy Duty Coating

DHDC-3660 Solvent-based epoxy top coat, high build

usage
Top coat for undercoated steel and concrete

This paint is a high build epoxy top coat that is excellent in wettability and adhesion to the primer. Since it is excellent in the hardness of film, adhesion, water resistance, salt water resistance, and chemical resistance, it is suitable for structures in a coastal environment and other heavy-duty structures. As it is a high build paint that can be applied as the dry film at a thickness of up to 100㎛ in one coat, it is a superior epoxy paint that can shorten the painting process and improve the durability of the entire film.

Excellent film property
Adhesion, salt water resistance, anti-corrosive properties, water resistance and chemical resistance are excellent.

how to use

Surface treatment
1. Completely remove oil, moisture, sand, dust, and other foreign matter from the surface to be coated.
2. Sufficiently dry the surface to be coated before coating.
3. The welded parts and corners need to be cleaned before coating.
Coating method
1. Although coating can be done by either brush or airless spraying, airless spray coating is best.
2. Airless spray coating :
- Tip diameter : 0.019"~0.025"
- Injection pressure : More than 3000 P.S.I (210㎏/㎠)
- Store the coating equipment after cleaning with an exclusive thinner immediately after use.
Preceding and follow-up coating
1. Preceding coating: Epoxy system, epoxy zinc and inorganic zinc primer
- Upon coating on the inorganic zinc paint, a mist coat is required.
2. Follow-up coating: Epoxy system, urethane system, PVDF paint
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 coat.
