APPLICATION TECHNIQUES
BARE STEEL APPLICATIONS
When working with bare steel applications, you MUST use an etching primer rated for steel. Scorpion has a product just for these types of applications - DTM.
DTM Etching Primer is a 2 component etching epoxy primer. It is applied to bare hardened steel surfaces only prior to 8001 and XO2 application. 8001 is not a sufficient adhesion promoter to bare metal surfaces by itself.
DTM is sold in 2 quart or 2 gallon sets containing an "A" and a "B" component. DTM is mixed at a 1:1 ratio. Once mixed DTM has a pot life of roughly 1 hour. Surface must be free of all wax, grease, dirt, and oil, etc. Rusted metal must be blasted or cleaned to white metal. Mix 1 part "A" to 1 part "B". After mixing allow to set for 15 minutes before using. Set air pressure at gun to 35-40 psi. Apply one even mist coat to dry film thickness of 0.5 to 1 mil. You should be able to see the substrate thought the mist coat of primer. Allow to dry 30 minutes before top coating. Do not use mixed material after 8 hours. Clean with lacquer thinner.
DO NOT APPLY XO2 DIRECTLY TO DTM.
DTM primed surfaces must be mist coated with 8001 and then XO2 can be applied within 24 hours or initial DTM application.
