ChemLine® 784/31

A coating with superior chemical resistance and high temperature resistance.

ChemLine 784/32


ChemLine® 784/31 delivers significantly improved product performance and anti-corrosion resistance. ChemLine® 784/31 is formulated with unique polymer technology, designed and engineered with high functionality. This translates in up to 784 cross-links versus four (4) for high temperature epoxies.

ChemLine® 784/31’s Higher Cross-Link Density Means:

  • Higher chemical resistance
  • Higher temperature resistance
  • Higher reactivity at lower temperature
  • Higher resistance to absorption
  • Higher toughness

Industry Applications

  • Chemical Processing - Tanks, flare tanks, reactor vessels, hazardous waste hauling, etc.
  • Paper & Pulp - Digesters, black liquor tanks, bleaching, etc.
  • Steel - Pickling tanks, acid storage, acid waste, neutralization, etc.
  • Mining - Acid tanks, scrubbers, etc.

More Chemical Resistance Than:

  • Stainless steel
  • Phenol epoxies
  • Vinylesters
  • Phenolic

Product Highlights

  • Superior bond strength and adhesion
  • Maximum product flexibility, product cycling
  • Field repairable
  • Low VOC - 99 grams/L (0.80 lbs.per gallon)
  • Can be applied to pitted and/or corroded steel
  • Steam cleanable
  • Complies with all FDA regulations
  • Virtually non-permeable for product purity

ChemLine® 784/31 Provides Superior Resistance To:

  • Acids, alkalies and solvents
  • Thermal cycling -40°F to 400°F (-40°C to +204°C)
  • Good flexibility
  • Wear and abrasion resistant
  • Minimal product absorption
  • Impact resistant
  • Resists under-creep corrosion
  • Dry heat resistance to 500°F (260°C)
