Epoxyden Primer Oven 150oC antirust. Denber paints & coatings

Epoxyden Primer Oven 150oC antirust

Electrostatic oven epoxy paint 150oC for 30 minutes

A one component anticorrosive stoving epoxy primer or mid. coat suitable for iron and aluminum metals. The product is a red/gray colored primer, contains over 75% solids! Based on Epoxy melamine resin mixed with iron oxides and zinc phosphate. Does not contains coal-tar no chromates and free of lead. The paint creates a strong primer layer with high adhesion to surfaces.

Properties:

Stoving antirust primer paint.
A primer with mechanical strength and has high adhesion to ferrous and aluminum metals.
Creates a proper preparation for a top layer stoving epoxy topcoat.
Anticorrosive primer protects ferrous metal against oxidation (rust).
Resistant to solutions of acids or of alkali also in extreme conditions of humidity and moisture.
The primer has excellent adhesion ability to the surface.
Useful to bridge between an old paint layers to a new top ones.
Easy to apply, dries 30 minutes in 150 oC.
Can be painted by spraying airless/pistola.
Thixotropic, suitable to produce in single spraying a thick layer.
Low surface strength makes it easily recoat able.
High coverage, economical.
Resistant to fuels & oils including for jets fuels.

Applications:

As stoving primer.

Surface preparation:

A thorough cleaning needed from dirt, dust and loose paints.
On old paint – sand well and clean with air pressure, clean with dry clean cloth soaked with thinner.
Iron Metals – recommended but not must – sand blast cleaning till white metal appears SA-2.5 level. Metal brushes clean -For rusty surfaces ST-3, for light rusty surfaces – ST-2.5, for galvanize steel – sandind until totally matte surface appears.
Very big surfaces –remove the paint with paint removers and wash with water for neutralizing. Sand/spray soft sands or plastic powder for light roughness. Rinse with water and dry completely.
For aluminum –burn with ANTAROX 4 and PASSIVATOR 1722 yellow/green, or spray layer of Epoxyden Stronzium Chromate MIL–C-23377 for best primer and this product as mid. Thick layer.

Primer:

This product itself.

Instructions for use:

Open carefully and stir welly.
Pour from can 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 50 microns thickness dry film and till 100 mic. if no licks apear. If necessary if the layer does not completely uniform or part of surface not painted, spray another layer. Insert into the oven for 30 minutes in temp. of 150 oC.
Wash the equipment well immediately after finishing painting.
