Steel-It Polyurethane Aerosol Black 14oz 1012B
STEEL-IT 1012B is a black one-component polyurethane aerosol in a 14 oz can with 316L stainless leafing pigment for metal and fab work. It goes direct-to-metal and leaves a finish with UV protection, washdown resistance, and later weldability.
- Protects steel and aluminum against corrosion, abrasion, salt spray, and harsh chemicals.
- Stays weldable after a full cure for TIG or MIG without stripping the finish first.
- Holds touch-up and small jobs at approximately 7.5 sq ft per can at 3 mils DFT.

STEEL-IT 1012B Black Polyurethane Aerosol - 14 Oz
STEEL-IT 1012B is a black one-component polyurethane aerosol in a 14 oz can loaded with 316L stainless leafing pigment. It goes direct-to-metal on steel, galvanized, and aluminum that need corrosion and UV resistance, and after a full cure the finish stays weldable for TIG or MIG on plant and fab equipment that sees weather, washdown, and abrasion outdoors and inside.

Key Features
- STEEL-IT 1012B is the 14 oz black polyurethane aerosol with 316L stainless leafing pigment.
- Direct-to-metal placement covers steel, galvanized steel, aluminum, and common fab substrates.
- The cured film resists corrosion, abrasion, UV, moisture, salt spray, and harsh chemicals.
- A full 7-day cure keeps the finish weldable for TIG or MIG on coated metal.
- The standard aerosol system builds four coats at approximately 1.5 mils DFT each for 6 mils total.
- Coverage is approximately 7.5 sq ft per can at 3 mils DFT on smooth metal.

Frequently Asked Questions
What metals and jobs is STEEL-IT 1012B made for?
STEEL-IT 1012B is the black polyurethane aerosol for touch-up, fab, plant equipment, motorsports, marine, and outdoor metal that needs UV and corrosion resistance. The TDS names steel, galvanized steel, aluminum, copper, brass, plastic, and fiberglass.
What film build does the black aerosol system need?
The TDS calls for four coats of STEEL-IT 1012B at approximately 1.5 mils DFT each (6 mils total). Harsh service can use six coats for approximately 9 mils total. Two coats at approximately 8 mils wet film each, 30 to 60 minutes apart, target approximately 3 mils DFT.
What temperature window applies when placing STEEL-IT 1012B?
Apply at 50 F to 100 F (10 C to 38 C) with relative humidity under 85 percent and the substrate at least 5 F above dew point. Dry to touch is approximately 1 to 2 hours. Shake the can vigorously for 2 minutes and spray from 12 to 16 inches. Full cure is 5 to 7 days.
What cure time is required before welding through STEEL-IT 1012B?
TIG or MIG after a full 7-day cure. When welding is not planned, STEEL-IT 2213 Epoxy Ester Precoat under the aerosol improves corrosion resistance.
Which other STEEL-IT packs match this black polyurethane chemistry?
Live sisters are the Gallon 1012G, Quart 1012Q, and the 12 oz aerosol 1012D. Steel Gray aerosol 1002D is the gray color match. Same black polyurethane family as the 1012 TDS aerosol column.
What coverage and solids does the aerosol TDS list?
Approximately 7.5 sq ft per can at 3 mils DFT on smooth metal (20 percent overspray assumed). Solids approximately 32 percent by weight. Net contents 14 oz (397 g) per can. Max in-service temperature 200 F (93 C). CA MIR under 1.25.
