It is low viscosity curing agent for epoxy resins specially developed for primer for concrete surfaces & potable water contact. Formulator can develop epoxy systems which are VOC compliant i.e. solvent less or high solids epoxy coatings systems. In general it shows ability to resist moisture while curing & also exhibit rapid cure even at low temperatures similar to other phenalkamines.
Novel Features :

  • Low viscosity
  • Excellent rapid cure even at low temperatures
  • Good chemical, solvent & water resistance
  • Very good compatibility with
    1. Epoxy resin based on bis - phenol A
    2. Epoxy resin based on bis - phenol 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
  • Superior corrosion resistance
  • Workable pot life at lower temperatures

Applications of Epoxy hardener PPA -7558
  • Medium to high solid coatings
  • Flooring & construction
  • Marine & industrial maintenance coatings
