 Description |
Protal
7200 is a VOC free, 100% solids epoxy
coating specially formulated to compliment
FBE coated pipe. It is a high build liquid
coating that is brush or spray applied
in one coat in the field or shop. It cures
very fast to allow quick handling and
backfill times.

Application
Brush:
Prepare surfaces by grit blasting
to a clean near white finish, SSC-SP 10/
NACE No. 2. Initially stir the base and
hardener. Add the hardener to base and
mix until a constant color is achieved
making sure all sides of container are
scraped. Pour mixed material onto surface
and brush, trowel or roll to required
mil thickness. A wet film thickness gauge
shall be used to measure mil thickness.
If surface temperature falls below 50°F
(10°C), surface must be preheated
to achieve cure. Preheat may be achieved
with a propane torch or induction coil.
Resin and hardener component shall be
kept warm, at a minimum of 68°F (20°C),
to mix easily.
Spray: Prepare surfaces by grit
blasting to a clean near white finish,
SSC-SP 10/ NACE No. 2. The equipment should
be a plural component airless spray unit
with a proportioning pump capable of a
volume mixing ratio of 3:1. Standard ancillary
equipment should include minimum 10 gallon
hoppers, static mixers, whip hose, and
mastic gun. (Applicator should consult
with Denso regarding recommended equipment).
A wet on wet spray technique should be
used to achieve a minimum thickness of
20 mils. The coating thickness should
be measured using a wet film thickness
gauge.
