02Why It Matters

Patented Polymer Technology, Elevated

ChemLINE 784 ES is formulated with unique polymer technology, designed and engineered with high functionality at elevated service temperatures

ChemLINE 784 ES is engineered for aggressive chemical environments where elevated operating temperatures place greater demands on the lining system. Leveraging the same highly cross-linked polymer functionality as ChemLINE 784, it provides a durable, chemically resistant barrier designed to maintain protective performance under prolonged thermal exposure and demanding service conditions.

 

 

Higher Crosslink Density Means

  • Higher chemical resistance
  • Higher temperature resistance
  • Higher reactivity at lower temperature
  • Higher resistance to absorption
  • Higher toughness
  • Resists under-creep corrosion

04Application Guidance

Operational requirements for a benchmark application.

Before anything else

Surface Preparation

Coating performance starts with the blast. Surface preparation is non-negotiable for MarineLINE® systems.

  • Surface must be abrasive blasted to SSPC-SP10 / NACE 2
  • Achieve 2–3 mil anchor profile
  • Remove all contaminants, rust, and prior coatings
  • Surface must be dry and free of chlorides

Mixing Instructions

  • Material components supplied in pre-measured units
  • Mix ratio: 1:1 by volume (A:B)
  • Use heated plural component spray equipment
  • Material temperature: 150–160°F (65–71°C)

Environmental Conditions

  • Substrate temperature: 50–120°F (10–49°C)
  • Relative humidity: <85%
  • Surface must be 5°F above dew point
  • No application during precipitation

Equipment Recommendations

  • Graco Reactor E-30 or equivalent
  • Heated hose length: 50–100 ft maximum
  • Spray tip size: 0.037–0.043 inch
  • Air pressure: 2000–3000 PSI

Cure Guidance

  • Initial cure: 4–6 hours @ 70°F
  • Return to service: 48 hours @ 70°F
  • Full chemical resistance: 7 days
  • Cooler temperatures extend cure time

06Proof & Validation

When you need superior protection.

Case Study

Tailored In-House Testing: ChemLINE® 784 ES Offers Superior Protection for Aggressive Waste Stream Environments

When a major hazardous waste disposal provider experienced ISO tank liner failure within a year of service, APC ran a tailored 192-day in-house immersion study comparing ChemLINE® 784 and ChemLINE® 784 ES against an aggressive waste stream, with no signs of coating breakdown observed.
