E Primer Force-Cure Epoxy for Field-Welded Joints up to 80°C by CANUSA-CPS

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 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.

Properties

Specifications

Property	CANUSA E Primer
Color	Black
Volume Solids	100%
Weight Solids	100%
Mixing Ratio	(by volume) - 4 parts of base to 1 part of cure (by weight) - 6.1 parts of base to 1 part of 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 & assuming 20% waste factor
Specific Gravity	E Primer Base - 1.58 ± 0.03 (ASTM D 1475) E Primer Cure - 1.04 ± 0.02 (ASTM D 1475)
Viscosity	E Primer Base - 14,000 ± 2,000 cps at 60°C, # 7 Spindle at 10rpm E Primer Cure - 30 ± 3 seconds (ASTM D1200 # 4 Ford cup @ 25°C)
Typical Thickness	4 to 6 mils (0.10 to 0.15 mm)
Number of Coats	One
Pot Life	20 minutes @ 23°C (73°F)
Shelf Life	3 years @ 23°C, out of direct sunlight. Shelf life will be lesser at higher temperatures.
Flash Point	E Primer Base - 93°C (200°F) E Primer Cure - 92°C (198°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 risks of fire and explosion.

Application

Prepare the pipe surface as recommended in the product-specific Installation Guide.
Follow the mixing instructions that are contained within the epoxy packaging.

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

Epoxy required for 300 mm / 12" cutback. For other cutbacks, divide by 12 and multiply by new cutback in inches.
Example: 200 mm (8") cutback on 610 mm diameter pipe
Base: 88 mL x 8/12 = 60 mL base
Cure: 22 mL x 8/12 = 15 mL cure

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.
