  • Description

    Powercrete® R-65/F1 is a solvent free epoxy coating with an extreme fast curing time for handling efficiency in pipemills and workshops, has user friendly application characteristics and rapid backfill properties. Powercrete® R-65/F1 provides excellent long term corrosion protection to abrasive blasted steel and FBE coated pipes. This high-build epoxy coating system can easily achieve a dry film thickness (DFT) up to 40mils (1000micron) in one multi-pass layer. Powercrete® R-65/F1 Repair Cartridges and Spray Cartridges are available to make this the ideal coating for girth welds, Touch-up and rehabilitation projects. Used for coating system for new construction and rehabilitation of pipes, pipe bends, fittings, valves, girth welds/field joints, buried tanks and other steel structures in need of protection.

    Inspection and Repair 

    Inspection  The finished coating must be visually inspected for any defects, such as runs and sags, fisheyes, blistering, pinholes, missed spots and possible contaminants. Pinhole/Holiday detection must generated according to NACE SP0188.
    Coating Thickness  The coating thickness (DFT) must be within the specified DFT range. Use calibrated equipment and measure according to SSPC-PA 2 or other specified standard.
    Repair  Pinholes/Holidays must be located and repaired with approved material. Consult Powercrete® for specific information. Retest the repaired area


    Cleaning & Handling 

    Cleanup  Use Acetone or MEK. 
    General  Transport and stacking is possible after full cure of the coating and generating a Holiday test (NACE SP0188). This time can be reduced by increasing the curing temperature. Consult Powercrete® for specific information.
