Product Description
CANUSA-CPS E Primer is a specially formulated 100% volume solids (solventless) two-component epoxy. Recommended use is as a primer in a three-layer coating system for superior corrosion protection of field welded joints of steel pipes.
Using Canusa's proven method of force curing the E Primer to the steel enables the installer to "pre-inspect" the joint prior to sleeve application. This provides the assurance that the pipe is fully protected and it will not be displaced and exposed to corrosive contaminants during the aligning and shrinking stages of sleeve installation.
Available in bulk quantity or bubble pack option, E Primer kits are provided with a pair of latex gloves and an application pad.

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 risks of fire and explosion. |
1. With a gloved hand, pour the combined mixture onto the pipe.
2. Begin spreading the epoxy primer (to a uniform thickness) circumferentially around the pipe surface using the applicator pad.
3. Use a wet film thickness gauge to ensure a correct, uniform thickness has been achieve all around the pipe.
Amount Required
1. Mixing ratio by volume of base to cure is 4 : 1. Therefore, for 1 US gallon of Base, 0.25 US gallons of cure will be required.
2. Due to pot life limitations, it may be impractical to coat multiple joints with the same epoxy kit.
