Editing Epoxy primer

{{youcanedit}} [[Image:54_Dodge_Coronet_in_primer.jpg|right|thumb|350px|A 1954 Dodge Coronet body with a fresh coat of epoxy primer.]] Epoxy primer/sealer is a non-porous finish that is typically recommended as the first basecoat over bare steel. Various epoxy primers can also be applied over fiberglass, plastic, or the black iron phosphate coating that remains after "converting" rust. Epoxy primer is a two-part mix, with a hardener that has to be added before spraying. ==Body filler and epoxy primer== Body filler and high-build primers can be used on top of epoxy primer. Although body filler is commonly applied to bare metal, applying epoxy primer before the filler adds adhesion, corrosion protection, and durability. Body filler is thought to be best applied over epoxy primer within the primer's recoat window time. Commercial body shops may not use epoxy primer under body filler because it's not time-efficient. An extra day must be allowed in the repair process for the epoxy to begin curing before filler can be applied. However, some car manufacturers specifically require epoxy primer to be used under body filler for certain applications. ==Spray (rattle) can epoxy primer== Because epoxy primer must be mixed prior to spraying, it hasn't conventionally been available in a spray can. However, "aerosol 2-component epoxy primer" has recently been introduced by [http://www.rubber-seal.com Rubber-Seal]. To release the activator into the primer, a plunger is inserted into a stem on the bottom of the spray can. Product literature states a pot life of four days. ==Tech sheets of epoxy primers recommended for automotive use== ===DuPont=== *[http://www.performancecoatings.dupont.com/dpc/en/us/html/prodinfo/chromasystemlv/H-19456_V-2910S.pdf DuPont V-29X0S DTM Epoxy Primer-Sealer] *[http://www.performancecoatings.dupont.com/dpc/en/us/html/prodinfo/hh/HHU-4010_AG.pdf DuPont Hot Seal DTM Epoxy Primer Sealer] ===House of Kolor=== *[http://www.houseofkolor.com/hok/PDF/TechData/English/2007/KP21.pdf KP21 House of Kolor Kwikure Epoxy Primer Surfacer] *[http://www.houseofkolor.com/hok/PDF/TechData/English/2007/KP2CF.pdf KP2CF House of Kolor Chromate Free Epoxy Primer] ===Martin Senour=== *[http://www.martinsenour-autopaint.com/pds/martin/english/8216.pdf Martin Senour 2.1 VOC DTM Epoxy Primer] *[http://www.martinsenour-autopaint.com/pds/martin/english/8206.pdf Martin Senour 3.5 VOC DTM Epoxy Primer] *[http://www.martinsenour-autopaint.com/pds/martin/english/8300.pdf Martin Senour 4.6 VOC Epoxy Primer-Sealer] *[http://www.martinsenour-autopaint.com/pds/martin/english/9114.pdf Martin Senour Crossfire Epoxy Primer] ===PPG=== *[http://www.ppg.com/refinishftpsite/docs/p-122.pdf PPG DP Epoxy Primer] *[http://www.ppg.com/refinishftpsite/docs/P-196_DPLF_Epoxy_Primer.pdf PPG DPLF Epoxy Primer] ===Southern Polyurethanes=== *[http://southernpolyurethanes.com/Tech%20Sheets/Epoxy%20Primer.htm Southern Polyurethanes Epoxy Primer] ===Valspar=== *[http://www.valsparrefinish.com/val/docmgmt/retrieveDocument.do?id=42 Valspar 999VP Epoxy Primer] *[http://www.valsparrefinish.com/val/docmgmt/retrieveDocument.do?id=40 Valspar 999VPLV Low VOC Epoxy Primer] [[Category:Body and exterior]]
