Advanced technology development of bi component primer epoxy flame retardant for steel coating antiflame fire protection systems as primer, anticorrosive and rust converter together in one product, high build, solids rich, can apply on light rusty metals without the need for perfect sand blasting, for metal profiles where perfect rust remover is not able to be done.

Epoxyden Primer AF Anti flame Antirust Rust Converter

STANDARD 755 + 931

Anti corrosive primer rich with zinc phosphate and rust converter elements, extremely strong with particularly unique molecular structure. Produced for requirements of partial preparing surface with easy rust residue. Provides a base strong paint layer with a high adhesion to iron metals that is also used as the basis before coating “Denbercryl Antiflame” against fire and top coat “Tutgum Antiflame” or “Denbergloss Antiflame”

Tested in Israel institute of standards – standard 755 and 931

Properties:

Flame retardant primer paint with high mechanical strength and high metal adhesion for iron rusty metals
Creates a worthy preparation for painting with Denbercryl Antiflanme” on it.
Anti corrosive and rust converter protects from oxidization and rust.
Durable in high moisture environment conditions and in alkali and acid liquids.
Offering a superior adhesion to iron rusty metals. Also used as bridge layer on old paints before painting the layer on top.
Easy to apply, quickly drying.
Ready to repaint/re-coating again on the same day or after 12 hours.
High coverage.
Durable in fuels including aviation fuel.

Applications:

As primer in fire protection paint systems for steel protection.

Mid. layer:

Denbercryl antiflame 8-12 hr. after the primer applying. In winter 24 hr. after applying the primer coat.

Top layer:

Denbergloss antiflame for UV protection and decoration. Also for durability in harsh extreme conditions like sea environment. Or Tutgum Antiflame for usual city conditions.

Instructions for use:

Open carefully parts A and B and stir separately.
Pour from two parts in the right ratio the required amount and mix well with mechanical mixer (operated by air pressure is recommended for safety reasons) for a uniform mixture.
Wait for 10 minutes while adding the thinner as needed and mix again. Spray a thin layer of at least 23 microns thickness dry film. If necessary if the layer does not completely uniform or part of surface not painted, wait about 4-12 hours for complete drying and spray another layer. Insert into clean and controlled temp. drying room for 12 hours before painting the top layer.
Wash the equipment well immediately after finishing painting.
