TPI EPOTAR 100 – Two-component epoxy coating, coal tar resin

TPI Epotar 100
Two-component solvent-based epoxy coating, coal tar resin composite.

DESCRIBE

TPI Epotar 100 It is a two-component epoxy and coal tar-based coating system with low solvent content.

TPI Epotar 100 After application, it will create a coating with high adhesion and good waterproofing on a variety of surfaces, effective corrosion resistance, and excellent chemical resistance.

APPLICATION

TPI Epotar 100 It is a chemical-resistant coating applied to:

• Wastewater treatment plant
• The bridge abutment is submerged in water.
• Steel or concrete storage tanks
• Oil storage tank
• Protecting steel structures
• Underground structures

TPI Epotar 100 It would not be suitable for application to surfaces in contact with drinking water.

ADVANTAGE

• Excellent chemical resistance.
• Excellent adhesion to most application surfaces (concrete, steel, etc.).
• Good corrosion resistance.
• Durable waterproof coating in chemical and wastewater environments.
• It can be applied as an interior and exterior coating for structures submerged in water for extended periods.

INSTRUCTIONS FOR USE

Surface preparation

Concrete:

• The concrete surface must be solid and have a minimum compressive strength of 25 N/mm².
• The surface must be clean, dry, and free of contaminants such as dirt, oil, grease, old coatings, and surface maintenance compounds.
• Weak concrete and dirt must be removed. Surface defects such as pits, voids, cracks, and bumps must be treated and smoothed.

Steel:

• The concrete surface must be solid and have a minimum compressive strength of 25 N/mm².
• In cases where the surface is submerged in chemicals, sandblasting is required to remove loose or contaminated components (rust paint, scale, etc.), ensuring a minimum surface area of 95% is well controlled.
• If the surface is not immersed in chemicals, all rust, scale, or foreign matter must be removed by degreasing (the surface must be maintained in a gray color); cleaning tools should be used as specified and recommended.
• For all cases involving metal surfaces, the coating must be applied within 4 hours and without delay after the surface has been prepared.

Check for moisture levels and apply a primer (if necessary):

• Check surface moisture, relative humidity, and dew point before application.
• If the surface moisture content is < 6%, an additional epoxy primer layer should be applied. TPI Primer FS.
• If the surface moisture content is >= 6%, an additional moisture-resistant epoxy primer layer should be applied. TPI Primer MB.

Mixing sequence:

• TPI Epotar 100 It is supplied in a two-component kit consisting of a base component A and a curing agent B.
• Component A must be thoroughly mixed separately first. Then add component B (the hardener) and mix thoroughly using an electric mixer, moving it up and down.
• The product is stirred until a homogeneous consistency is achieved, free from lumps and sediment, ensuring that no air bubbles remain in the liquid mixture.

Coating application:

• Apply the mixed product using a brush, roller, or traditional spray equipment, including vacuum spray.
• Apply the first coat in a fixed direction. Then apply the second coat perpendicular to the first, after the first coat has dried, usually within 24 hours.

Toilet:

• Clean equipment and tools immediately after use with thinner or common solvents. Once the paint has hardened, it can only be removed by mechanical means.
