Tec/SYSTEM® 2.1 VOC DTM Epoxy Primer-Surfacer is low VOC, two-component primer offering excellent direct-to-metal adhesion and corrosion resistance over properly cleaned steel and aluminum substrates without the use of lead or chromates. These primers may be topcoated within as soon as 30 minutes after priming.
DTM primer is in fact a highbread epoxy that is fortified with urethane resins and therefore has the sticking characteristics of conventional epoxy but the body and filling capability of urethane surfacer. It also is much faster at reaching sandability than a conventional epoxy.
Also Know, do I need epoxy primer? Epoxy primers have excellent adhesion properties and will stick to bare metal, paints, primers and fillers. Alternatively, you can apply filler or primer surfacer over the epoxy to fill any minor imperfections and block flat before you paint.
Consequently, what is epoxy primer used for?
Epoxy primer is a sealer that produces a good surface finish on applied top coats. A two-part epoxy primer contains zinc phosphate, which acts as corrosion-inhibiting pigment. Epoxy primers can be used to waterproof materials that consequently protect the bare metal from oxidation.
What is the difference between epoxy primer and etch primer?
Epoxy primer is catalyzed and self etching is solvent based. Self etching primer bonds well to bare metal surfaces and can be top coated in a short period of time. Epoxy primer can be applied in heavy coats which can be guide coated and block sanded to remove small imperfections in the body.

What are 2k paints?
“2K” Paint Systems. Two-component paints (also referred to as 2K paints) are paints in which a chemical reaction results in paint hardening. The static mixer ensures that the hardener is homogeneously mixed with the base paint. The mixed material is fed to the spray gun through a hose and atomized at the nozzle.
How long can you leave epoxy primer?
