CANUSA P Epoxy Primer
High Temperature
Epoxy Primer
Used for corrosion protection of
field welded joints of steel pipes or as an
overcoat in multi-layer sleeve systems at temperatures to 140°C (284°F).
 Product Description
Canusa-CPS P Epoxy/Primer is a
specially formulated 100% volume solids (solventless) two-component
epoxy with a high temperature range to 140°C (284°F).
P Epoxy/Primer is typically used as an epoxy primer in a
three-layer coating system for
superior corrosion protection of field welded joints of steel pipes or
as an overcoat in multi-layer sleeve systems. Usage of Canusa's proven
method of force curing the P Epoxy/Primer to the steel enables the
installer to "pre-inspect" the joint prior to field joint application.
This provides the assurance that the pipe is fully protected and it will
not be displaced and exposed to corrosive contaminants during field
joint installation.
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.

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 of 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. |

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:
92 mL x 8/12 = 62 mL base
Cure:
23 mL x 8/12 = 16 mL cure |
