DESCRIPTION
RUST-OLEUM® CombiColor Metal 7300/7400 coating is primer and topcoat in one, based on a urethane modified alkyd, providing good drying properties at low temperatures. The product contains rust-inhibitive pigments and is lead- and chromate free.
RECOMMENDED USE
RUST-OLEUM CombiColor Original 7300/7400 should be applied on bare, manually derusted or with CombiPrimer Anti-Corrosion 3369/3380 primed steel. CombiColor Original is intended for brush and roller application and can also be applied by air spray. RUSTOLEUM CombiColor Original 7300/7400 offers corrosion protection in a light industrial environment. For metal structures in a more aggressive industrial environment, prior application of a RUST-OLEUM CombiPrimer Anti-Corrosion 3369/3380 is recommended.

RECOMMENDED WET FILM THICKNESS 100 µm
RECOMMENDED DRY FILM THICKNESS 55 µm
THEORETICAL CONSUMPTION 10.3 m²/l at 55 µm dry, depending on colour
PRACTICAL CONSUMPTION Practical coverage depends on many factors such as porosity and roughness of the substrate and material losses during application.
SURFACE PREPARATION
Remove oil, grease and all other surface contaminations by alkaline or high pressure (steam) cleaning in combination with appropriate detergents. Remove rust scale, loose mill scale, loose rust and loose coatings by scraping and wire brushing to St 3 (ISO 8501-1 : 1988), light blast cleaning or sanding. Sand intact coatings to roughen the surface slightly. The surface must be clean and dry during application. Galvanised, Zinc and Aluminium surfaces have to be primed first with CombiPrimer Tack Coat 3302.
DIRECTIONS FOR USE To ensure homogeneity, coating materials should be thoroughly stirred prior to use.
APPLICATION CONDITIONS Temperature of air, substrate and coating material between 5° and 35°C and relative humidity below 85%. The substrate temperature must be at least 3°C above dew point.
APPLICATION & THINNING: BRUSH Up to 10% volume RUST-OLEUM Thinner 7301. Use natural bristles, long hair brushes.
APPLICATION & THINNING: ROLLER Up to 10% volume RUST-OLEUM Thinner 7301. Use short nap, polyamide 6-12 mm rollers. Roller application may require 2 coats to achieve recommended dry film thickness
APPLICATION & THINNING: AIR-ATOMISED SPRAY 10-25% volume RUST-OLEUM Thinner 7301. Gravity cup and pressure cup. Tip size: 1.0 - 1.5 mm. Atomising pressure: 2 - 4 bar.
CLEANING OF EQUIPMENT / SPILLS Use RUST-OLEUM Thinner 7301 or RUST-OLEUM Thinner 160.
REMARKS Maximum dry film thickness per coat: 75 µm dry, equals 135 µm wet. To avoid inhomogeneous appearance with aluminum colored coatings it is recommended to spray 7311 with HVLP. CombiColor Metal 7300/7400 can be recoated with 7300 Aerosols within 4 hours or after 72 hours.
