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.

Curing Times at 25ËšC (77ËšF)
Gel Time: 12 minutes Dry Time: 37 minutes 65 Shore D: 1 hour (ready for holiday test) 75 Shore D: 75 minutes (full cure) Cure time is based on 40 mils (1000 micron) DFT. Recoat interval at
21ËšC (70ËšF) is 34-60 minutes and 4-7 minutes at 65ËšC (150ËšF)
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 & HandlingCleanup 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. General Order Information

Application
Application Instruction: Surface Preperation Steel
General The area to be coated has to be clean, dry and free from oil, grease and dust. All contamination that could interfere with the adhesion of the coating has to be removed according to SSPCSP1. Preventing condensation on the subtrade Prior and during the surface preparation, the temperature of the substrate(s) must be at least 5ËšF (3ËšC) above the dew point. Abrasive Blasting Minimum Sa2½ (SSPC-SP10/ NACE2) . Recommended Surface Profile 3-4mils (75-100micron) angular profile.
Application Instruction: Surface Preperation FBEGeneral The area to be coated has to be clean, dry and free from oil, grease and dust. All contamination that could interfere with the adhesion of the coating has to be removed according to SSPC-SP1. Preventing Condensation on the substrate Prior and during the surface preparation, the temperature of the substrate(s) must be at least 5ËšF (3ËšC) above the dew point. Abrasive Blasting Sa1 (SSPC-SP7/NACE4, sweep-blasting for optimum performance. Recommended Surface Profile Minimum 2mils (50micron) angular profile.
