02Why It Matters

Why ChemLINE 784 AS

ChemLINE 784 AS (Anti-Static) is a highly chemically resistant conductive coating engineered for aggressive environments where static electricity must be managed.

It is specifically designed for applications where static build-up and sparks may present operating hazards, combining ChemLINE's proven chemical resistance with conductive and static dissipative properties. ChemLINE 784 AS cures to an extremely chemically resistant, hard, conductive finish with excellent abrasion and wear resistance, and can be ambient cured over time or lower temperature forced air cured for immediate service.

 

Performance Advantages

  • Excellent conductive and static dissipating properties
  • Superior bond strength and adhesion
  • Highly resistant to wear, abrasion, and impact

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
