Canusa-CPS S Primer is a specially formulated 100% volume solids(solventless) two component epoxy. As a primer in a three-layer polyethylene coating system for superior corrosion protection of field welded joints of steel pipes. The primer has extended pot life at high temperatures, which allows for longer working time.

1. Prepare the pipe surface as recommended in the product-specific Installation Guide.

2. Follow the mixing instructions that are contained within the epoxy packaging.

3. With a gloved hand, pour the combined mixture onto the pipe.

4. Begin spreading the epoxy primer (to a uniform thickness) circumferentially around the pipe surface using the applicator pad.

5. Use a wet film thickness gauge to ensure a correct, uniform thickness has been achieve all around the pipe.

Safety

Handle with care. Before and during use, observe all safety labels on packaging and paint containers, consult CANUSA Material Safety Data
Sheets and follow all local or national safety regulations. Harmful or fatal if swallowed; immediately seek medical assistance if swallowed. Avoid inhalation if possible solvent vapors or paint mist, as well as paint contact with skin and eyes. Apply only in well ventilated areas and ensure that adequate forced ventilation exists when applying paint in confined spaces or when the air is stagnant. Always take precautions against the risks of fire and explosions.

Epoxy required for 600 mm / 24" cutback. For other cutbacks, divide by 24 and multiply by new cutback in inches.
Example: 200 mm (8") cutback on 610 mm diameter pipe
Base: 300 mL x 8/24 = 100 mL base
Cure: 100 mL x 8/14 = 33 mL cure

Small diameter ø represents joints completed with one installer. As a general rule, only one installer is required up to 18” (450 mm) pipe sizes.
Latex gloves associated with Bulk Accessories are heavy duty and can be used for more than one joint.
For large projects, joint specific pre-measured epoxy quantities (other than standard 400 mL) will be considered.
