Replacement product for D847 Scansealer


DP620 PrimaSEAL is ideal for the rapid repainting of sound original substrates.

PrimaSEAL is a transparent sealer, with its filling properties promoting excellent gloss holdout of 2K topcoats over a range of substrates. These include OE finishes, sound aged paint surfaces, and non-synthetic primer-surfacers.

For the repainting of Electrocoat, OE or other sound paintwork, PrimaSEAL will also perform as a simple adhesion promoter, eliminating the requirement to detail sand the substrate.

PrimaSEAL can be used wet-on-wet with Deltron DG, BC topcoat, and since it is transparent it is especially suited to respray work, avoiding the need for long and delicate masking around doorshuts, panel edges etc. PrimaSEAL may be tinted with up to 10% by volume with Deltron DG tinter.

Preparation of Substrate:

Sealer Adhesion Promoter
Bare Steel Must be preprimed Must be preprimed (eg DP612, DP614)
Galvanized Steel Must be preprimed Must be preprimed (eg DP612, DP614)
Zintec Must be preprimed Must be preprimed (eg DP612, DP614)
Aluminium & alloys Must be preprimed Must be preprimed (eg DP612)
Electropaint D837 / Red Scouring Pad D837 / Red Scouring Pad
Aged Painted Surfaces P400-P500 (dry) / P400-P600 (wet) Clean thoroughly (light abrasion on difficult areas)
Primed Surfaces P400-P500 (dry) / P600-P800 (wet)

Electrocoat, Sound OE or existing paintwork should simply be cleaned thoroughly with red Mirlon and D837 using a wipe on wipe off method. Areas susceptible to stonechip damage, leading edges, wheel arches or sills, for example, will benefit from additional adhesion if abraded thoroughly with a red scouring pad.

Prior and after any sanding operation, the substrate must be thoroughly degreased using D845 for the 1st clean, and D837 for the 2nd clean.


Application Guide:

Hardener and Thinner Selection:

Hardener Thinner
Up to 18'C DH710 DT810
18'C - 25'C DH720 DT820
25'C - 35'C DH730 DT830

PrimaSEAL may be tinted by addition of up to 10% by volume of Deltron DG tinter or uncatalysed mixed DG colour prior to addition of hardener and thinner.

When overcoating PrimaSEAL wet-on-wet with Deltron DG or Deltron BC and Clearcoat, it is important to use the same or a slower hardener in the topcoat as used for the application of PrimaSEAL.

In normal use it is not necessary to sand this product. Use P400 grade (dry) or P600 –800 (wet) if required.


Overcoat / Recoat Time:

Overcoat without sanding within 24 hours of application. In order to ensure good adhesion if left longer than 24 hours, or in order to remove dirt or defects, PrimaSEAL may be sanded after it has through dried.

Overcoat with: Any PPG Deltron Topcoat. See ‘Hardener Selection’ above for choice of topcoat hardener.


Performance Guidelines:

  • Do not use 1K, synthetic or cellulose topcoat over PrimaSEAL.
  • If required, PrimaSEAL may be coloured with up to 10% by volume of Deltron DG Tinter. Select only Deltron DG Tinter, and do not exceed this mix ratio. Additional thinner may be required in order to achieve correct application viscosity.
  • Deltron Accelerator thinners should not be used in PrimaSEAL.
  • Technical tip: Small dust nibs may be sanded through the Deltron basecoat one it has flashed off, rather than waiting for the PrimaSEAL to through dry
