Element of strontium chromate used as rust converter rich with zinc phosphate, particularly strong with a unique molecular structure. manufactured in accordance with the requirements of the contents of zinc and chromates, cadmium is prohibited and lead content max. 0.06%, tints as listed in standard strontium chromate greenish gray tint.

Paint creates a primer foundation layer with high adhesion to parts that maid of iron metals and aluminum. Parts treated according to the U.S. Fed. St. Also used as the mid. layer “bridges” the old paint before you recoat with a polyurethane top aliphatic paints.

Surface Preparation:

Clean surface from dust, fat, dirt and loose paint.
Old coat – sand well and clean with dry air, clean with clean rag dipped in thinner.
Aluminum alloy/aluminum exposed or new – treatment of chemical burn and passivation according to space preparation devices: MIL-C-5541 MIL-C-81706
Iron metals – sand blasting cleaning up to SA- 2.5 standard (white metal)
Very large parts – remove paint with paint removers and flash with water, spray plastic soft granular to complete stripping and rinse thoroughly and dry.

Top color:

You can paint top color on primer 8-12 hours after painting. If primer was spread in appropriate conditions.
During cold winter you can paint after 24 hours.
The matching paints are all types of aviation top layer paints for aircraft and space including CARC paints.

Instructions for use:

Open carefully parts A and B and mix separately.
Pour two parts A and 1 part B to the required amount and mix well with mechanical mixer (recommended air mixer) for a uniform mixture.
Wait 10 minutes while adding thinner and mix again.
Pour to painting equipment and spray thin layer for at least 23 microns dry. If necessary if the layer is not uniform or part not painted perfectly, wait approximately 4 hours (up to 12 hours if not dry completely you will receive a shrinked layer) and spray another layer.
Insert into sealed and clean and dry room with temperature control for 12 hours before paint overlay.
Clean equipment after work.
