      Surface Preparation:

Master Series may be applied by brush, roller (short nap) or spray (atomizing or airless.)  These coatings are moisture cured and it is extremely important that the surface be free of moisture prior to the coating application.  Moreover, 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.  Use a minimum of two coats, full strength. 

Caution: for spray application - a fresh air supplied mask should be worn such as #W-292 mfg. by 3M.  It is important that the spray droplets of paint, not be inhaled.

Important: Thinning is not recommended.  If thinning is required, not more than 5%.  Thinning can adversely effect the corrosion fighting properties of this coating.  Use MCT 101 Thinner. 

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 the bottom of the container.  Use only low speed mixing and avoid developing a vortex as this will introduce moisture into the system which can cause gelling. 

      New Metal Surfaces/Clean Steel:

Scuff with 220 grit and use Metal Prep to insure maximum adhesion where sandblasting has not been done.  Metal Prep should be wiped with damp cloth, then dried thoroughly. 

Remove the trim and blow dirt and dust from the channel.  Place cardboard over the dash.  Thin MCU Silver slightly and pour or brush between the glass and the channel.  The MCU will travel the same route as the water and cut off the leak.  Two applications may be necessary.

  TIP - Rotten Gas Tank

Thoroughly clean tank with rust removers such as Rust Away to remove the rust and use an etching solution such as Metal Prep to treat the galvanized metal.  Rinse with water, inside and out and allow to thoroughly dry.  Paint 2 coats of silver on the outside of the tank, pour remainder of the can on the inside and slosh the MCU over the interior of the tank.  Pour the MCU back into the can and replace the lid.  Apply the second coat 4 hours later, stand tank on end allowing it to drain completely.  Let cure 48 hours before use.  Thin coats are recommended, do not allow coating to puddle. 

3 coats of Master Series applied over rusty steel with an "X" scribed through the center of the plate.  After 14,000 hours exposure only slight undercutting at spots along the scribed "X" was noted and this was less than 1/32" undercut.  Total film thickness 8.0 mils approximate.

Outdoor Exposure

Two coats of Master Series, approximately 6.0 mils DFT, applied to rusty panel and exposed for 5 years - showed no signs of lifting of paint film or blistering and no apparent rusting.

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 2,000 hours, the coating appeared in very good condition with no apparent undercutting along scribed "X."

Heat Test:

2 coats of Master Series were applied to sandblasted 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.

After curing for 7 days at room temperature, panels coated with Master Series 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 aliphatic.  Alcohols and glycols showed no attack.  Moreover, ester solvents such as ethyl glycol acetate has no effect on the coatings.

Harmful or fatal if swallowed. 

 If swallowed, do not induce vomiting.  Call physician immediately.

PRECAUTIONS:

Contains aliphatic 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 by 3M should be used.

Please 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. 

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.
