Ressi EPO Roll Coat plus is based on diluted Bisphenol A based Resins and Diluted Polyamide based curing agent. The recommended thickness for Ressi EPO Roll Coat Plus is from 50 to 200 microns in a single coat. Ressi EPO Roll Coat Plus is also suitable for a variety of substrates such as wood, metal, fiberglass and selected plastics. Its anti-fungal and anti-bacterial properties make it an ideal coating for vertical wall applications for hospitals and other health care facilities.

ADVANTAGES

• Suitable for multi-layer applications
• Easy to apply
• Does not support algae or fungal growth
• Good resistance to sea water and solvents
• Suitable for old and new concrete surfaces

SURFACE PREPARATION

Steel: The base metal should be roughened and preferably shotblasted with grit. Where shot blasting is not possible pre-treatment may be carried with tap hammers, rotary wire brushes or by flame scaling. Cleaning with solvent or a strong detergent is advisable to ensure the surface is free from grease, oil, paint, and other contaminants. Ressi EPO Roll Coat Plus must be applied before the oxidation of steel occurs. Surface defects revealed by the blast cleaning process, should be treated in an appropriate manner with a suitable repair mortar within the Ressichem patch series of material which is compatible with both steel and subsequent epoxy materials.

CONCRETE / CEMENTITIOUS SURFACES:

Concrete and cementitious surfaces must be dry, clean, and free from mold, oil, curing compound, dirt, grease, oil, or excessive laitance. Surface should be prepared by suitable mechanical means. To provide an open pore surface. Cracks, pinholes, potholes, etc. should be routed out and repaired with a suitable epoxy-based crack / void filler from the Ressichem range for the repair of Uneven concrete surface. The concrete surface should be levelled to produce a roughened flat surface. Undulated floors can be levelled / repaired using suitable floor repairing materials from the Ressichem range prior to application of Ressi EPO Roll coat Plus. All internal corners should be covered using a suitable epoxy compatible material from the Ressichem range or as approved by the consultant or client having samples on site applied and approved. Sharp edges should be rounded off. New concrete floors must be at least 28 days old prior to application. Moisture content of concrete surfaces must be less than 5%.

MIXING

Ressi EPO Roll Coat Plus is supplied in premeasured packs. Bases and hardeners should be stirred separately before mixing. After stirring individually, transfer base into mixing container, mix for a minute. Add hardener component and mix using a slow speed drill machine fitted with a paddle mixer for two minutes to get a uniform mix. Scrape the sides, edges and the bottom of the mixing container using a spatula and continue mixing for further 1 minute.

APPLICATION

Ressi EPO Roll Coat Plus mixed as above can be applied using a suitable squeegee, stiff nylon brush or roller. Work the material into the surface to ensure total absorption into the substrate. Finish off using a medium-to-long nap roller. Make sure that the required application rates are achieved to ensure minimum dry film thickness per coat. Spray application is also a preferred method to accurately obtain the required dry film thickness. Minimum of 2 coats should be applied to achieve the desired performance. Prior to the application of each coat the surface should be examined for signs of pinholes, cavities etc. where pinholes are apparent these can be filled using either Ressi EPO Crack Fill or Patch Epoxy 111 Repair Mortar. The second coat should be applied at right angles to the first to get the desired dry film thickness. Second coat should be of different color than that of the coat.

For large water tank areas where coating is expected to undergo high pressure, it can be strengthened by using 3 coats and fiber glass mesh. Consult Ressichem for details.

LIMITATIONS

At higher temperature pot life will be reduced. For working in cold climates (<5°C) Ressi EPO Roll Coat Plus containers need to be kept in hot water bath.
