Uses
MasterSeries MCU is a maintenance primer and finish coating for
interior and exterior use over steel and masonry surfaces where
a high degree of chemical, abrasion and corrosion resistance is
required. This coating is generally used as a primer on steel
and galvanized surfaces where only marginal surface preparation
can be achieved. It can be used as a primer for enamel, lacquer,
and two part epoxys. MasterSeries can be used as a topcoat where
gloss retention is not a critical factor, i.e., as an aluminum
roof paint. Because it has excellent salt corrosion resistance
properties, MasterSeries has been widely used in marine atmospheres.
It has found use on steel tanks, stacks, piping, metal building
paneling, trucks, railcars, bridges, etc.
MasterSeries is supplied as a one package product to be applied
as supplied. THINNING IS NOT RECOMMENDED. IF THINNING IS REQUIRED
NOT MORE THAN 10%, THINNING CAN ADVERSELY EFFECT THE CORROSION
FIGHTING PROPERTIES OF THIS COATING. USE MCT 101 THINNER OR URETHANE
REDUCER.
TEST DATA
Salt spray, 5% (ASTM B117)
3 coats of MasterSeries applied rusty steel with an "x" scribed
through the center of plate. After 14,000 hours exposure only
slight undercutting at spots along a scribed "x" was noted and
this was less then 1/32" undercut. Total film thickness 8.0 mils
approximate.
Weatherometer
Cycle consisted of 30 minutes light, 125°F, 30 minutes dark, 80
F, 100% R.H. Panels were prepared as for above salt spray using
rusty substrate, after 2000 hours the coating appeared in very
good condition with no apparent undercutting along scribed "x".
Outdoor Exposure
Two coats MasterSeries approximately6.0 mils DFT applied to rusty
panel and exposed for 5 years showed now signs of lifting of paint
film or blistering and no apparent rusting.
Heat Test
2 coats of MasterSeries were applied to sand blasted panels and
subjected to 350°F for 15 days. Although slight yellowing occurred,
there appeared to be no loss of adhesion or blistering of film.
Solvent Resistance
After curing for 7 days at room temperature, MasterSeries coated
panels were subjected to various solvents and found to be extremely
resistant. After 30 days exposure there was no failure or noticeable
attack by solvents such as xylol, toluol, or other aromatics.
Alcohols and glycols showed no attack. Also, ester solvents such
as ethyl glycol acetate had no affect. Acetone softened the film
after 10 days, although it hardened upon removal. Methylene chloride
destroyed the film in two days. Gasoline diesel fuel and JP.4
jet fuel had no affect on the coatings.
Surface Preparation
Previously painted and rusted surfaces, for optimum surface preparation,
sandblasting is recommended. However, in situations where sandblasting
is not permitted or restricted. MasterSeries can be applied over
tightly rusted surfaces, so long as the rust profile is covered
by at least 1 mil. It is necessary to remove all oil, grease,
loose scale or rust and loose paint using a stiff wire brush,
by hand tool cleaning or by other suitable means. This coating
will adhere well to light and tightly rusted surfaces and will
arrest further rusting.
APPLICATION
MasterSeries may be applied by brush, roller (short nap or foam),
or spray (atomizing or airless). These coatings are moisture curing
an d it is extremely important that the surface be free of all
moisture prior to coating application. Also, the coating should
dry for a minimum of one hour at 75°F and 50% R.H. prior to being
subjected to moisture (rain); longer at lower temperatures and
relative humidity. Caution: for spray application, a fresh air
supplied mask should be worn such as #W-292 mfg. by 3M Co. It
is important the spray droplets of paint not be inhaled.
IMPORTANT: clean equipment immediately after use. If coating is
allowed to harden on equipment, industrial paint stripper is required
to remove it. Do not thin for application.
Stir prior to use to assure that no settled pigment remains at
bottom of container. Use only low speed mixing and avoid developing
a vortex as this will introduce moisture into the system which
can cause gelling. Keep lid on container when not in use and store
only in dry areas.
All other coatings or alcohol-content solvents must be thoroughly
flushed from application equipment prior to application of MasterSeries.
Refer to material safety data sheet and package label.
New Metal Surfaces/Clean Steel
Scuff with 220 grit and use Captain Lees Metal Prep to ensure
maximum adhesion where sandblasting has not been done.
PRECAUTIONS
Contains aromatic polyisocyanate prepolymer. Use adequate ventilation.
In confined areas, use adequate forced ventilation during application
and drying. When spraying, a fresh air mask such as W-292 manufactured
by 3M Co. should be used.
Harmful or fatal if swallowed. If swallowed, do not induce vomiting.
Call physician immediately. Eye irritant. Wear eye protection.
In case of contact with eyes, flush repeatedly with water and
contact a physician. Difficult to remove from skin. Wear protective
clothing. Moisture in skin will cause rapid curing. Do not attempt
to remove cured coating on skin with solvent; soak in warm, soapy
water. Barrier creams are not recommended where possible to cover
with protective clothing. Combustible. Keep away from heat, sparks,
and open flame. Refer also to safety data sheet.
Note: Although this coating composition is not a fire retardant
product, it will not support combustion and will self-extinguish
when the source of fire is removed.

AUTOMOTIVE RESTORATION
MasterSeries Permanent Rust Sealer/Surfacer is recommended as
a base primer for any other paint system. It is also used to seal
rust and old paints and to level heavy pitting. This base primer
is air tight and compatible with any other paint. It will extend
the service life of ordinary paints dramatically. MasterSeries
Permanent Rust Sealer/Surfacer should be used in any part of the
car where recurring rust is a problem. MasterSeries Silver is
not generally used on exhaust systems.
MasterSeries Silver Primer will add structural strength to sheet
metal that is severely rusted and will fill in pinholes. Multiples
coats are usually recommended. For sanding purposes, we recommend
220 grit dry. The use of gloves and protective clothing cannot
be overemphasized. This coating once dried is immune from solvent.
Wear rubber gloves!
MasterSeries Silver will not rust beyond a scratch or chip. Highly
recommended under stainless steel trim clips, backs of bumpers,
and anywhere the surface will be scratched during assembly.
FOAM ROLLERS WORK ESPECIALLY WELL FOR FLOOR PANS, FRAMES, AND
INNER PANELS.
GAS TANKS INSIDE AND OUT
ACID ETCH THOROUGHLY WITH CAPTAIN LEES METAL PREP AND CONDITIONER.
THIS WILL DISSOLVE THE RUST AND ETCH THE GALVANIZED SURFACE. DUMP
ENTIRE CONTENTS OF CAN INTO THE TANK SENDING UNIT. SLOSH THOROUGHLY.
DUMP ENTIRE CONTENTS OUT. STAND TANK UP ON END AND LET DRY FOR
48 HOURS. THIN COAT IS RECOMMENDED. DO NOT ALLOW IT TO PUDDLE
