Farwest has been a distributor of Canusa-CPS products of heat-shrinkable materials for girth welds, HDD applications, flanges, bends, elbows, T’s and risers for decades

Force-cure epoxy for superior three-layer corrosion protection of field welded joints of steel pipes.

Description

Product Description

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.

Application

Prepare the pipe surface as recommended in the product-specific Installation Guide.
Follow the mixing instructions that are contained within the epoxy packaging.
With a gloved hand, pour the combined mixture onto the pipe.
Begin spreading the epoxy primer (to a uniform thickness) circumferentially around the pipe surface using the applicator pad.
Use a wet film thickness gauge to ensure a correct, uniform thickness has been achieve all around the pipe.

Properties

Specifications

Property	CANUSA S Primer
Color	Black
Volume Solids	100%
Weight Solids	100%
Mixing Ratio	(by volume) - 3.0 parts of S Primer base to 1 part of S Primer cure. (by weight) - 4.6 parts of S Primer base to 1 part of S Primer cure.
Typical Coverage	20 sq.m./US gallon (215 sq.ft/US gallon) or 5.3 sq.m/liter (57 sq.ft/liter). This coverage is based on 6 mils of thickness and assuming 20% waste factor.
Specific Gravity	S Primer Base - 1.58 ± 0.03 S Primer Cure - 1.02 ± 0.02
Viscosity	S Primer Base - 14,000 ± 2,000 cps @ 60 C, #7 spindle at 10 rpm. S Primer Cure - 250 ± 50 cps @ 25°C, #3 spindle at 20 rpm.
Typical Thickness	4 to 6 mils (0.10 to 0.15 mm)
Number of Coats	One
Pot Life	140 minutes @ 23°C (73°F), 30 minutes @ 40°C (104°F).
Shelf Life	3 years @ 23°C, out of direct sunlight. Shelf life will be lesser at higher temperatures.
Flash Point	S Primer Base - >93°C (200°F) S Primer Cure - >93°C (200°F)
Thinner	Do not dilute.
Minimum Curing Temperature	10°C (50°F)
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.

Amount Required

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

¹ ²

Mixing ratio by volume of base to cure is 3.0 : 1. Therefore, for 1 US gallon of Base, 0.33 US gallons of cure will be required.
Due to pot life limitations, it may be impractical to coat multiple joints with the same epoxy kit.

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.
