Technical Application data

Preparation of substrate surface prior to the application of CRP is extremely important. A minimum spray film thickness of 16 mils will provide adequate cathodic protection. The surface temperature must be 5° above dew point and no condenstaion is present on the surface. CRP requires the metal surface be clean/dry and free from corrosion or contaminates; i.e. loose rust, paint, moisture, dirt, oils, etc. Normally, grinding and/or sanding is sufficient. If application surface exhibits extensive corrosion, standard sand media blasting is reccommended to create a secure 6 mil surface texture preparation, typically blast clean to SSPC-SP 10. CRP may be applied over very lightly dry rusted prep-sanded surfaces. Aluminium must be acid prepped, washed and dried prior to spray application. Always power clean using steam and mild detergent prior to any sanding operation as to not spread or induce contamination into preped surface. This product is appled using high pressure heated plural component liquid pumping equipment. Product may be headed up to 120°F. Surface application temperature may range from 20°F to 150°F. Spray gel time at 75°F is 30s-5min. Extended tacky time may be formulated up to 4 hours. Functional operation temperature ranges from -40°F to 250°F. Recommended minimun application film thickness is 16 mils to provide cathodic protection. Multiple coats may be sprayed if desired. Final sprayed surface is glossy smooth. Refer to MSDS for material and safety standard procedures. Store materials in dry environment. For long storage, displace air in drums with Nitrogen. Always wear safety gear for breathing and full-face protection at all times.

Substrate Surface Preparation

Preparation of substrate surface prior to the application of SuperSkinSystem is extremely important as durability is only as good as the weakest link in the coating system.

Call TechSupport Group for assistance with the selection of a SuperSkinSystem™ protective coating system. Also read the Application Page on this website. It is always best to perform a test within a small section of the application area prior to full scale engagement.
