Epoxy zinc phosphate primer
Two-component, solvent-borne polyamide cured epoxy with corrosion inhibitive pigments.
As a primer coat on steel prior to application of epoxy or polyurethane coatings or single-pack anti-corrosive coatings.
- Exhibits excellent corrosion protection of steel
- Contains corrosion inhibitive pigments
- Easily overcoated with decorative epoxy or polyurethane twin-packs
- Good pot life allows for flexibility during application
Steel should preferably be abrasive blast cleaned to a minimum standard of SA 2,5 of Swedish Code of Practice SIS 055900. The anchor pattern should be approximately 40 – 60 microns. If hand cleaning is used, nothing less than a SA 3 finish is acceptable. However, this method of cleaning will significantly reduce the life of the system.
All metal to be coated must be clean, mechanically sound and dry.

Bonding / Priming
The product is a corrosion protective primer. For subsequent top coats of epoxy or polyurethane applications prime the abecote® 384 with abecote® 386 for improved bonding and superior finishing.
Stir contents of each container, particularly the base, very well. Add the activator to base and stir together for at least five minutes using a flat paddle. Mechanical mixing gives better dispersion than manual mixing. A suitable mixing method would be a slow speed electric drill (approximately 200 r/min) fitted with a paddle.
If only part of a kit is to be used, add one volume of activator to 4 volumes of base. Measuring must be accurate and separate stirrers used for proportioning each component. The mixed material must be left to stand in a cool place for 20 minutes prior to application.
8 – 10 m2/l.
By brush or airless spray. In the latter case, a tip of approximately 250 μm size may be used abecote® 384 should not be applied if the ambient temperature is below 10 °C. The curing reaction will not occur at low temperature.
If surfaces are not at least 2 °C above dew point, there is every chance that a fi lm of condensed moisture may be present. This will interfere with the adhesion of the coating. Wet film thickness as per recommendation should not be exceeded as this can result in solvent entrapment, as can too early overcoating. Solvent entrapment in the film can lead to disastrous performance. Stir frequently during use.
Tools can be cleaned with abe® super brush cleaner before material has cured.
Protection on Completion
Against traffic and spillage until cured.
Temperature & Relative Humidity

Two component epoxy zinc phosphate primer for metal surfaces. The coating shall be abecote® 384, a two component epoxy zinc phosphate primer applied to prepared metal surfaces in accordance with the manufacturers recommendations, a.b.e.®
abecote® 384 is supplied in 5 l kits.
Handling & Storage
This product has a shelf life of 12 months if kept in a dry cool place under cover in the original packaging. In more extreme conditions this period might be shortened.
Health & Safety
Wet abecote® 384 is toxic and flammable. Always ventilate the working area well during application and drying. Avoid flames in vicinity. Always wear gloves and eye protection when working with the material and avoid excessive inhalation and skin contact. If material is splashed in the eye, wash with copious quantities of clean water and seek medical attention.
