Stronghold Coating Systems has introduced Blue Dichtol, a modified impregnation coating for new (and newly repaired) castings. 

  • Compatible with all ferrous and nonferrous materials and composites
  • Impregnates micro-pores and hairline cracks without vacuum or pressure, forming protective barrier to gases and liquids
  • Can be applied to raw metal, or to castings that have been coated with plasma, arc spray or HVOF (High velocity oxygen fuel spraying) coatings 
  • Provides exceptional capillary action, penetrating to 0.004 in. (0.1016 mm), restoring pressure tightness and enhancing surface and varnish properties
  • Proprietary engineered polymers penetrate deeply (up to 20 mm/0.79 in.) into the coating, preventing corrosion of metal substrate   
  • Blue tint provides positive visual proof that porosity has been sealed and casting repairs have been completed as specified
  • Does not alter part dimensions
  • Can be applied on-site for repair that is both quick and convenient
  • Provides resistance to chemicals, mechanical stress and temperature extremes following air cure of approximately 1 hour per mm wall thickness
  • Cured coating is pressure resistant to 8,700 psi, and heat resistant to 932 degrees
  • Dampens vibration 
  • Can be applied to clean, fully dry parts by immersion, brush or spray
