ADVANTAGES

• Excellent food grade properties.
• Excellent adhesion to the surface corrosion, protection properties.
• Good temperature / abrasion resistance properties.

APPLICATION

• Internal coating for potable water pipelines.
• Internal coating for potable water storage.

APPLICATION METHODOLOGY

• Prepare surface by mechanical grinding, shot blasting conforming to SA2½.
• Remove dust, flakes, oil, grease or other loose foreign particles by sand blasting, iron brush or compressed air.
• Stir drums of each component thoroughly for uniformity. For best result, use a variable speed drill mixer with a spiral type blade at the bottom of stirrer rod. The speed may be 400-600 rpm. Pre heat part-A @ 50-65°C and Part-B @ 25-40 °C.
• Apply CLI Guard 40 by plural feed airless spray gun to the required thickness on the substrate.
• The tip pressure typically 2500-4000 psi (the tip pressure should be adjusted to achieve good atomization of the spray).
• Tip size typically 19-25 Thou orifice.
• The coating repair should be done by brush application with the same material provided the mixing quantity of Component A and component B should be done as per requirement of the repairing job because of the lower pot life of the material. Mixing will be done in a drill type mixer. For repairing job, heating of individual component is not required.
