2 Loctite Nordbak Chemical resistant coating is an impervious ceramic composite that offers an ultra smooth glossy surface. This technology significantly improves and reduces the surface friction that causes boundary drag". The improved surface smoothness assists where applications require maximum fluid flow efficiency whilst protecting against abrasion, turbulence, corrosion/erosion under typical service temperatures of -29 C to +160 C. Typical applications include resurface tube sheets, condensers, cooling pump impellers, butterfly valves and cavitated pumps, line tanks and chutes, resurface and repair rudders and pintle housings, line Chemical containment areas.

9 For safe handling information on this product, consult the Material Safety Data Sheet (MSDS). Directions for use Surface Preparation Proper surface preparation is critical to the long-term performance of this product. The exact requirements vary with the severity of the application, expected service life, and initial substrate conditions. 1. Clean, dry and abrade application surface. The more thorough the degree of surface preparation the better the performance of the application. If possible, it is recommended that the surface be grit blasted to a Near White Metal (SSPC-SP10/NACE No. 2) Standard. For less severe applications roughening the surface with hand tools is suitable. 2. Solvent cleaning with a residue-free solvent is recommended as the final step to aid in adhesion.

10 Mixing: 1. Material temperature should be between 18 C to 27 C. 2. Mix the entire contents of resin and hardener. If smaller amounts are required, mix parts resin to 1 part hardener by volume, or parts resin to 1 Part hardener by weight. 3. Mix vigorously, 3 to 5 minutes, until a uniform color is obtained. Application Method: 1. Apply fully mixed material to the prepared surface. 2. Immediately clean any contaminated skin or clothing with soap and water. 3. Material can be applied with a 3/8 nap roller with a good core. Once applied, back roller with 3/8 nap roller to smooth out the product and provide a smoother finish. Caution: Use an approved, positive-pressure, supplied air respirator when welding or torch cutting near cured compound.
