Aromatic Moisture Cured Urethane

 

DESCRIPTION

MCU 2100 type IV is a single pack, stainless steel filled, urethane coating designed to afford superior abrasion and chemical resistant properties that out perform conventional epoxies and polyurethane. Steelcote MCU 2100 uses a high quality, 18/8/316 grade stainless steel flake improves adhesion during application to power tool cleaned, rusted surfaces when dry abrasive blasting is not possible. Its quick dry, low temperature application properties and overall chemical resistance make it a high quality, multi –functional maintenance coating.

 

APPLICATIONS

As a primer and a finishing coat for the protection of steel or galvanized metal in corrosive or highly abrasive environment. An excellent coating for structural steel, machinery, tank exterior, weather galvanized and wire –brushed rusted surface.  Ideal for floor applications where superior abrasion resistance is needed. May be applied on concrete, wood, steel and non –ferrous metal.  Excellent when used for secondary chemical containment areas and food contact on food processing equipment. Should not be used for class I Immersion service.

 

PRECAUTIONS

NOTE: Ensure surfaces are thoroughly dry before applying. Do not apply MCU 2100 Type IV over concrete containing release agents, curing compounds or hardeners without consulting Technical Finishes Sales Representative Department for details.

 

DIRECTIONS

SURFACE PREPARATION

TO CONCRETE: Allow new concrete to cure a minimum of twenty-eight (28) days at 15oC for proper bonding, apply over clean, dry, sound surface. Remove any existing oil, grease, wax, dirt, loose or foreign matter by washing with a solution of Phosbrite and warm water. Flush with clean water and allow to dry thoroughly. Obtain tooth and remove any existing laitance on the concrete floor by lightly grinding or Concrete etching. If etching, neutralize. Flush clean with water and allow to dry thoroughly.

Apply steelcote MCU 2100 Type IV. When more than one coat of MCU 2100 Type IV is to be applied, apply the second coat within twenty-four (24) hours. Two coats are normally recommended. Clean all tools and equipment with Solidkote 503 after use.

TO STEEL: Surface must be clean and free from oil, grease, moisture, loose and foreign  matter. For best performance, dry abrasive blast to a Commercial finish. Avoid blasting with Coarse abrasives. Prior to blasting, remove any grease, oil, wax or contaminants. After aggregate blasting, remove all aggregate, dust and grid by brushing or vacuuming and apply Steelcote MCU 2100 Type IV as soon as possible after aggregate blasting.

TO GALVANIZED STEEL: Surface must clean, dry, sound and free from oil, wax, grease, loose and foreign matter. If white rust exist or galvanized surface are weathered, prepare by  degreasing and hand or power tool cleaning. Apply the Steelcote MCU 2100  Type IV. When more than one coat of MCU 2100 Type IV is applied, apply the second coat within twenty-four (24) hours. Two coats are normally recommended.

TO WOOD: Surface must clean, dry, sound and free from oil, wax, grease, loose and foreign matter. Repair all loose boards and fill holes. Remove surface deposit of sap or pitch by scraping and wiping with solvent. Sanding with medium grid sandpaper is recommended. Apply MCU 2100 Type IV. When  more than one coat of MCU 2100 Type IV is applied, apply the second coat within twenty-four (24) hours. Two coats are normally recommended.

 

APPLICATION EQUIPMENT

BRUSH: Use a clean, natural brush. Reduce up to 15% with Xylene, only if necessary
ROLL: Use a short nap, mohair roller with a phenolic core. Reduce up to 15% with Xylene, only if necessary.
