Fillers, anticorrosive pigments.
Hardeners polyamide.
Zinc phosphate.
solvents
additives

Color:

Standard yellow.
Red/Brown, grey.

Gloss:

Matt < 5% (ASTM D 523) with 60^o

Touch dry time:

12 minutes to 5 hours. (This parameter is affected by ambient temperature, due to the fast drying on a hot day – avoid while spraying from over spray “dust”)

Dry time between layers:

6-8 hours. Final: 8 hours.

Application method:

Brush, roller, spraying.
Spray gun – inner pressure 4 atm.
Airless – 0-5% dilution nozzle 0.021″

EPOXYDEN 3034 NOVOLACK

Top layer chemicals protection for concrete and metal

Dilution:

D-4/100 thinner (MIL-T-81771 Type II)
Brush – 10-25% volume according to need if appearance of “orange peel” you can increase the dosage to 35% .
Spray gun – 10-25%
Airless –0-5%

surface preparation:

Clean from dust, grease, dirt and loose paint.
Old paint – sand well and remove dust with air pressure and clean with cloth moistened with thinner.
Ferrous metals: new steel – we recommend cleaning with sand blasting to SA 2.5 – a white metal, maintenance works – for rusty surfaces: mechanical brush cleaning – ST3, and without rust – ST2, galvanized steel – sand until matte surface until no bright areas.
Very large objects – paint removing with paint remover MZ-83 and rinsing with water to neutralize.
Sanding or spraying soft plastic/sand and cleaning.

Primer:

Instructions for use:

Open carefully parts A and B separately and mix each well.
Pour from both parts the necessary quantity in the right ratio and mix well with mechanical mixer (best operated by air pressure, for safety reasons).
Wait 10 min. and mix again while adding thinner as required.
Pour to the paint sprayer and spray smooth uniform layer for at least 23 microns thickness and until 300 microns if there are no leaks.
If necessary if uneven layer or part not painted perfectly, wait about 4 hours (up to 12 hours if not dried out completely or else the layer might collapsed or shrink, shrinkage depends on the amount of thinner in the paint , as having less thinner so you can paint thicker layer without contraction, on a hot day allow the thinner evaporate before spraying another layer)
Rinse well painting equipment after finish painting.

Pot Life after mixing A+B of 5 liters:

At temperature 15^oC – 4 hours
At temperature 20^oC – 3 hours
