It is developed to get faster curing at low temperatures so as to get multiple coats at lower temperatures . It provides very good corrosion & water resistance properties. It gives very good adhesion to difficult substrate like inorganic zinc primers. Hence, Paladin PPA-7088 is an ideal solution for general purpose epoxy coatings.
Novel Features :

  • Low viscosity
  • Excellent rapid cure even at low temperature
  • Good chemical, solvent & water resistance
  • Very good compatibility with
    1. Epoxy resin based on bisphenol - A
    2. Epoxy resin based on bisphenol - F
    3. Epoxy resin based on phenolic novolacs
  • Non critical mixing ratio
  • Excellent curing under humid as well as damp conditions
  • Good adhesion to mechanically cleaned surfaces
  • Superior corrosion resistance
  • Very good flexibility
  • Workable pot life at lower temperatures

Applications
  • Medium to high solid coatings
  • Flooring & construction
  • Marine & industrial maintenance coatings
  • Tank linings
