Replacement product for D839 Prima


Deltron DP602 PrimaPRIME is a G3 shade grey 2K primer-surfacer suitable for a wide range of day-today repair work in the refinish bodyshop. Versatile, quick-drying, easy to apply and sand, it offers excellent corrosion resistance, film build, surface levelling and gloss holdout over a wide range of substrates.

PrimaPRIME may be applied directly to sound original paintwork, polyester bodyfillers and suitable adhesion primers. It may be directly overcoated with Deltron Basecoat or Deltron Direct Gloss.

By simple adjustment of the thinning ratio, PrimaPRIME may be applied as a conventional primer surfacer, as a high-build spray filler and as a wet-on-wet surfacer. PrimaPRIME may be air-dried, lowbaked or IR cured.

PrimaPRIME may be tinted as necessary with up to 10% by volume of Deltron DG colour.

Performance Guidelines:

When spot priming with PrimaPRIME as a Spray Filler / Primer Surfacer, adopt the following procedure:

  1. Ensure that the surface is thoroughly sanded to the panel edge, breakline or to a distance 15 centimetres beyond the feathered edge area, whichever is the smaller.
  2. Apply the first coat to the entire area to be primed then apply subsequent coats inside the previous coat allowing the correct flash-off times between coats. (This avoids building up an edge and trapping dry spray.)
  3. Allow to dry as normal, then be careful to thoroughly level the repair edge when sanding. Do not attempt spot repair on original or refinish TPA, lacquer or 1K finishes.
  4. DT860 Primer Accelerator Thinner may be used in air dry mode in PrimaPRIME.
  5. Do not use DT860 Primer Accelerator Thinner if the primer is to be baked or cured with IR lamps or if higher ambient temperature curing conditions are likely to be experienced.
  6. PrimaPRIME and its ancillaries are sensitive to moisture, so all equipment must be perfectly dry. Where humidity is in the range 70-80%, use of DT840 Extra Slow Thinner is recommended. Do not attempt to use PrimaPRIME at humidity levels exceeding 80%.
  7. To ensure maximum adhesion and impact resistance, PrimaPRIME must be topcoated within 72 hours of application. After this time it should be sanded and recoated with itself
