MCU Chassis Black

Master Series Custom Chassis Black provides a chassis coating that is very durable, corrosion resistant, and has a high degree of chemical and solvent resistance and an extremely high chip resistance. 

      Surface Preparation:
 Previously painted and rusted surfaces - for optimum surface preparation, sandblasting is recommended.  Apply two coats of Master Series Silver Permanent Rust Sealer/Primer.  If sandblasting can't be done, scrape/wire brush all loose paint and heavy rust and apply two coats off Master Series Silver Rust Sealer as per container directions and top coat with Master Series Chassis Coating.  Master Series Chassis Coating can be directly applied over tightly adherent rust, but the use of Master Series Silver Primer will extend the service life 20 to 25 years.

      New Metal Surfaces:
 New metal surfaces should be sandblasted for optimum adhesion.  This is to provide an anchor pattern and to remove mill scale from hot rolled steel.  Where sandblasting cannot be done, the use of an acid based metal prep is recommended.  Scuff new metal with 220 grit sandpaper to insure maximum adhesion.

      Application:
 Application temperature should be above 50° F.  Apply in thin coats, heavy coats will result in bubbling.  Clean brushes with urethane reducer if brush marks occur.  Persistent brush marks: reduce black 5% with reducer.

MCU Black may be applied by brush, roller (short nap) or spray (atomizing or airless.)  MCU Black can be brushed on with a nylon paint brush and will not leave brush marks.  These coating are moisture curing and it is extremely important that the surface be free of all moisture prior to coating application.  Moreover, the coating should be dry for a minimum of one hour at 75° and 50% R.H. prior to being subjected to moisture (rain,) longer at lower temperatures and relative humidity.

MCU Black should be stirred for a minimum of 2 full minutes.  This ensures that the carbon black pigment will flow out smoothly.  If grittiness occurs, continue stirring the container until grittiness is dissolved.

Technical Specifications:

Origin

Made in the USA

Important: Clean equipment immediately after use.  If coating is allowed to harden on equipment, industrial paint stripper is required to remove it. 

Reduction: 5% for spray applications if needed.

Recommended Thinners:

MCT 101, xylene or Naptha

Application Temperature:

Minimum 25° F

Recommended Coats:

2 coats

Recoat Time:

3 hours minimum, 48 hours maximum

Sunlight Sensitivity: Master Series Custom Chassis Coating (black) is sunlight sensitive.  It is not recommended for areas exposed to sunlight such as wheels, bumpers, and outer body.  For areas exposed to sunlight, AG 111 is recommended. 

Drying Time - 75° F, 50% relative humidity:

To touch - 0.7 hours
Tack free - 1.25 hours
Hard dry - 3 hours

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.

TEST DATA: Salt Spray, 5% (ASTM B117)

2 coats Master Series Permanent Rust Sealer, 1 coat Chassis Black applied to a rusted panel with an "X" scribed through the center.  After 14,000 hours of salt spray exposure, only slight undercutting was noted along the "X."  This was less than 1/32" undercut. 

Heat Test:

2 coats Master Series Chassis Coat applied to rusted panels and subject to 350° F for 15 days.  There appeared to be no loss of adhesion or blistering of film.

Solvent Resistance:

After curing for 7 days at room temperature, Master Series Chassis coated panels were subject 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 aliphatics.  Alcohols and glycols showed no attack.  Ester solvents such as ethyl glycol acetate has no effect.  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 effect on the coating. 

Cautions: Difficult to remove from skin.  Wear gloves and protective clothing.  Moisture in the skin will cause rapid curing.  The use of gloves cannot be overstated.

Harmful or fatal if swallowed. 
 If swallowed, do not induce vomiting.  Call physician immediately.

Capt. Lee's Spra' Strip, Rust Away, and Metal Prep & Conditioner are valuable companion products in the restoration effort.
