Gel Time: 30 minutes Dry Time: 1.7 hours 65 Shore D: 4.2 hours (ready for holiday test) 75 Shore D: 5.2 hours (full cure) Cure time is based on 20 mils (500 micron) DFT. Recoat interval at
21ËšC (70ËšF) is 26-83 minutes and 7-10 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.
Application SafetyGeneral Read the Product Data Sheet and follow the caution statements on the Material Safety Data Sheet . Personnel who will come into contact with the product should be using appropriate protection equipment. Follow national safety guidelines.

* If the surface to be coated is below 10ËšC (50ËšF), preheating of the substrate is recommended.
Preheat temperatures should not exceed 80ËšC (176ËšF).Prior and during the application, the temperature
of the substrate must be at least 3ËšC above the dew point.
Application Instruction: Plural Component SprayStep1 Mix the Part A and B until uniform in consistency Step2 Use only heated plural component Airless equipment capable to maintain a 4:8:1 ratio in volume and 1.25 Gallon/4,73 Liter per minute output, with heated drums, insulated (heated) hoses and minimum 170bar (2500psi.) fluid pressure for Part A and 124bar (1800psi) for Part B. Use Binks 1M Airless spray-gun or equal with preferably changeable spray tips. Consult Powercrete® for specific information. Step3 Part A must be heated up and maintained to a temperature of 54ËšC (130ËšF) and Part B must be heated up and maintained at 20-30ËšC (68-86ËšF). Step4 Apply Powercrete® J in the recommended DFT. Use a WFT gauge to check. Do not dilute the product.
