Power rust preventive EP 039

NETIS registration No.KT-120046-A

Maintenance and new equipment!
Drastic cost cutting!!

Easy to use, strong anti-rust,super thick film!!
Even only badly rusted surfaces!!

POWER RUST PREVENTIVE EP039 is a high solid epoxy
primer that can build dry ﬁlm thickness over 75u per coatfor excellent resistance to friction, chemicals andmoisture. EP039 is a 2-component modiﬁed polyamide
epoxy primer that allows for a long recoating time up to30 days. EP039 prevents rust and corrosion on steel,galvanized steel (both cold and hot dip), non-ferrous
metals, and concrete. Furthermore, EP039 prevents
concrete deterioration. EP039 is a high performance
primer that is eﬀective, economical and easy to use.

◆ Thick coat up to 75u dry film thickness per coat.
Cost down due to just one coating!!
◆ For various surfaces including steel, galvanized steel(both cold and hot dip), non-ferrous metals, concrete, etc.
◆ Very simple. Minimum surface preparation.
◆ Compatible with many topcoats.
◆ Easy 1:1 mix ratio.
◆ Excellent chemicals resistanceand resistance to friction and moisture.
◆ Effectively stops rust in progress.

Directions for use
1. Remove loose rust with a common tool such as a hammer. Then perform
minimum surface preparation (SSPC-SP-2) with sandpaper or wire brush.
2. Remove surface of all contaminants including dirt, chemicals, oil, grease,seawater, alkalis and acids. Rinse thoroughly with fresh water. Allow todry completely.
3. Thoroughly mix base component. Then, mix activatior thoroghly.
4. Mix base component and activator at 1:1 ratio. Thoroughly mix for
3 to 5 minutes.
5. After using, wash equipment and containers with reducer or thinner.
※ Exposure to sunlight and the elements can cause fading, yellowing andchalking. But the corrosion resistance will not be adversely aﬀected.
※ Beware of low curing temperatures and condensation on the ﬁlm whilecuring because they can cause blushing.

Cautions
10kg set (Base component/5kg, activator/5kg)【Standard application amount】 159-265g/ ㎡【Dry time】 16hrs（recoating time up to 30 days）
Ｆormaldehyde Emission Standard Rating T18026

Ｆ☆☆☆☆
（For interior）● In most cases, AP089 can be applied immediately after mixing.
In cold temperatures, allow 30 minutes before applying.
● Keep container closed when not in use. Activator must beused within 1-2 months.
● If necessary, reduce 5-10% with urethane reducer.
● Apply it at more than 10C within 80% humidity.
● Apply on edge and volt with brush beforehand.
