Description
Replacement product for D834 - DP40 Chromate-Free 2K Epoxy Surfacer
Deltron DP614 EpoxyPRIME is a versatile 2K Epoxy Surfacer. It is light grey in colour, chromate-free and has good corrosion resistance over bare metal.
EpoxyPRIME has good adhesion to a wide variety of suitably prepared substrates. These include bare and galvanised steel, GRP, fibreglass, painted surfaces and fillers.
EpoxyPRIME is ideally used as a wet-on-wet or non-sand surfacer, but may be baked or airdried if required. It may also be used as a one-coat sealer over flatted Deltron primers and surfacers, where it fills sanding marks, rub throughs and promotes optimum gloss holdout in the topcoat.
EpoxyPRIME is also an excellent sealer for use over TPA finishes.
Preparation of Substrate:
- Bare Steel: P80-P120 (dry)
- Galvanised steel: Red Mirlon Scoring Pad / P400 (dry)
- Zintec: Red Mirlon Scoring Pad
- Aluminium & alloys: Use D831 Universel Etch Primer
- Electropaint: P320-P400 (dry) / P600-P800 (wet)
- Aged painted surfaces: P320-P400 (dry) / P600 (wet)
- GRP, Fiberglass: P240-P320 (dry)
- Polyester filler: P120-P180 (dry)
Cleaning: Before and after any sanding operation, the substrate must be thoroughly degreased using D845 or D837.

Sanding:
In normal use it is not necessary to sand this product.
Overcoat with: Any Deltron Primer or Deltron DG Topcoat
Performance Guidelines:
EpoxyPRIME should not be used at temperatures lower than 10°C or humidity higher than 80%.
EpoxyPRIME should be overcoated within one week of application after de-greasing with D837 and a red Mirlon scouring pad wiping dry as you go, followed by a final de-grease with D837. If left for longer, the paint film must be degreased with D837 and abraded with a red mirlon scouring pad. After a further degrease, apply 1 additional coat of EpoxyPRIME and allow to dry for 15 minutes before application of primer and/or topcoat.
If used over TPA, EpoxyPRIME must be overcoated with Global topcoat within 8 hours.
Where spray or hand applied Polyester Body filler is necessary PPG recommends the use of DP616 EpoxyTHANE. NOTE: PPG cannot warrant paint systems where spray polyesters or body fillers have been used due to the vast amount of variables and types used, that occur when using these products.
