MRO COLD GALVANIZE COATING
PRODUCT NUMBER:
I. GENERAL DESCRIPTION
Description: Aervoe’s MRO Cold Galvanize Coating is a cost
effective zinc spray coating that imparts temporary zinc protection
in the welding process from fabrication, to maintenance, and
repair. One coat will furnish short-term corrosion protection in
pre-fabrication and the weld-through process including cut, drill,
and spot-weld activity. Provides a post process metallic primer
plus protection for incomplete work. Multiple coats (3 to 4) will
give you a dry-lm thickness of about 1-mil of zinc for extended
protection. MRO Cold Galvanize Coating uses metallic zinc dust
that is 97% pure and the dry lm contains 93% zinc.
Benets: The coating dries to a tough, hard coat and acts
as a metallic primer for iron, steel, and their welds to provide
interim protection during the work process. Even at one coat, if
the surface is scratched or broken; an electrochemical reaction
(sacricial anodization) causes the zinc to sacrice itself for the
base metal’s protection though at a faster rate than a coating of
1-mil. Even if moisture is present, the zinc coating will corrode,
but it will continue to protect the metal to which it is applied.
It protects surfaces by resisting salt, moisture, and heat. Can
be the nal protective coating when applied at 1 to 2 mils dry-
lm thickness or it can be top coated with Aervoe’s 188 MRO
Bright Galvanize Coating. If a color top coat is preferred, use
DTM water-based Rust Proong paint. MRO Cold Galvanize
Coating is an economical choice for preventive maintenance on
galvanized parts and in welding applications. Meets multiple
performance requirements of ASTM and MIL specications (see
“Specications”). Acceptable as a coating in federally inspected
meat and poultry plants for application to structural surfaces or
surfaces where there is a possibility of incidental food contact.
Application: Use on weld points, damaged galvanized
surfaces, structural steel, automobiles, guard rails, bridges,
TV and radio towers, storage tanks, signs and sign posts,
equipment (farming, mining & construction, power plant,
railroad, offshore, etc), gutters, pipelines, transformers, and
corrugated metal buildings.
Directions: Apply directly to metal or galvanized surfaces
that are free of loose rust, heavy mill scale, old paint, grease,
moisture, and other contaminants. Clean severely rusted areas
with a wire brush to remove loose scale. For best results, use at
temperatures between 60° and 80°F (16° to 27°C). Application
of heat will accelerate dry time. Notice: Zinc is a dense material
which will settle on the bottom of the container. This product
is formulated to resist hard settling (where zinc is dry, clumped
together and will not remix). However, soft settling (the zinc
sinks to the bottom but remains wet, no clumping, & will remix)
is natural for this product and can occur from road vibration
during transportation or while sitting on the shelf. Aerosol
application: align spray head with black mark on valve rim to
insure complete evacuation of contents. Vigorously shake can
for 2 minutes after hearing rattle of agitator ball (ball should
release in 10 to 30 seconds), and intermittently (1 to 2 seconds)
during use. Apply from a distance of 10 to 12 inches. Spray in
light, sweeping strokes to avoid run and sags. Two light coats
are better than one heavy coat. Whenever you must set the
aerosol can aside for more than 2 minutes or are ready to store
the can, then invert the can and spray for two seconds to clear
dip tube, valve and tip to prevent zinc from drying in those areas
and clogging the can.
Limitations: Please refer to the Safety Data Sheet for
specic information on material hazards, etc. Do not apply at
temperatures below 40°F (4°C), or if rain is imminent within 6
hours of application. Galvanizing products have a limited shelf
life; use them within 12 months from the date of manufacture
(guarantee is for 6 months from date of purchase and 12 months
from date of manufacture).
