TWO COMPONENT HIGH SOLID FOOD GRADE EPOXY COATING
CLI Guard 40 is WRAS Approved Food Grade Epoxy Coating for internal coating of pipes, vessels and other equipments used for portable water. It conforms to BS 6920:2000 and AWWA C 210.
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.

CLEANING & MAINTENANCE
Clean all tools immediately after use with CLI cleaner.
HEALTH & SAFETY
• Use mask, nose cover and hand gloves during application.
• Clean hands with soap water after application.
• Ensure adequate ventilation and avoid inhalation of vapours as some people are sensitive to resins, hardeners and solvents.
