Typical Uses

ATLAS® Barrier Sealant is applied to wire brushed or grit blasted metal, such as the exterior of pickling tanks, reaction vessels, scrubbers, rinse tanks, tank cars and plating tanks, as well as structural members. ATLAS® Barrier Sealant improves the adhesion of coatings to the substrate when grit blasting is impractical or when optimum adhesion is desired. ATLAS® Barrier Sealant reacts with metal substrates, such as galvanized or clean steel, toform a rust-inhibiting film which can be painted. ATLAS® Barrier Sealant can be used as a base for MEMBRANE 88, Data Sheet 4-31PI.

Mixing And Application of The Chempruf Tie-coat

Wipe surface clean of all contaminants, such as oil, dirt and dust to expose neat resin. Use a mild detergent if necessary. Lightly sand the surface to be repaired, again removing all dust.

Combine one part of CHEMPRUF TIE-COAT Component A with four parts of CHEMPRUF TIE-COAT Component B, by weight, or one part of component A with five parts of component B, by volume. Mix until uniform. Apply a thin coat to substrate with brush or short nap roller. Allow CHEMPRUF TIE-COAT to Cure for a minimum of 2 hours at ambient temperature before application of CHEMPRUF Lining System. Complete cure has occurred when hard to fingernail. Actual cure times will vary depending on temperature and humidity conditions. If CHEMPRUF TIE-COAT has cured for more than 24 hours, a new application of CHEMPRUF TIE-COAT must be made before applying the new lining.

To ensure maximum performance of CHEMPRUF TIE-COAT bonding system, the following precautions should be taken:

  • Protect CHEMPRUF TIE-COAT Components A and B from exposure to moisture. Reseal opened containers and keep tightly sealed.
  • For best results, temperature should be approximately 70°F (21°C) to 75°F (24°C) and relative humidity approximately 50% to 60%. Do not apply if temperature is below 55°F (13°C) or higher than 90°F (32°C).
  • Humidity must be between 40% and 85%.
  • Do not apply in direct sunlight.
  • Conduct small scale tests to determine if conditions are suitable for use of CHEMPRUF TIE-COAT in a particular application, i.e. surface cleanliness and profile, ambient temperature and humidity, etc.
  • Pot life of CHEMPRUF TIE-COAT is approxi-mately 1 hour at 80°F (27°C). Discard after this time.
Cleaning Of Tools and Equipment

Solvents, such as methyl ethyl ketone, toluene or xylene, will remove the materials referred to in this Data Sheet from mixing tools and equipment if cleaning is done immediately after use. If the material has been allowed to Cure, tools may be soaked in methyl ethyl ketone. Dispose of residues and wastes in accordance with the directions in the Safety Data Sheets and govern-ment regulations.
