Transtar 2K EZ Sand Acrylic Urethane Primer

EZ Sand Acrylic Urethane Primer is a premium grade lead & chromate free two component primer surfacer. It provides exceptional fill and build characteristics providing a base that yields excellent top coat hold out, gloss and D.O.I. (distinctness of image). This primer sands easily wet or dry and can be directly topcoated with alkyd enamels, acrylic enamels, alcquers and basecoat/clearcoat systems. Mix ratio is 4:1:1 (four parts primer, to one part activator, to one part Transtar® Urethane Reducer based on shop temperature).

Features and Benefits

  • Observe flash times to provide good cure times, reduce shrinkage and avoid solvent pop.
  • Best adhesion results are achieved if top coated within 8 hours, best holdout is achieved if primer is allowed to cure overnight.
  • Wet sand with 400 grit and final sand with 500/600 grit; or dry sand with 320 grit sand paper. Follow topcoat manufacturer’s instructions for proper sanding and recommended application techniques.
  • When using over lacquer, always complete the entire panel. Spot repairs may lift around the repair.
  • PPG recommends using a Sealer when using DAU over 2K Acrylic Urethane Primers.
  • Can be accelerated with Kicker (TDS700). Follow recommendations on the technical datasheet.
  • Caution: Accelerated products should never be used direct-to-metal.
