About Rust-Oleum Alkythane 7500
Rust-Oleum Alkythane 7500 top coats are based on a urethane modified alkyd resins that provide good drying properties at low temperatures.
The coatings are lead and chromate-free and contain rust-inhibiting pigments (except for 7510 clear) for additional protection.
Suitable for light industrial environments.
For metal structures in a more aggressive industrial environment, application of an additional RUST-OLEUM Alkyd primer or Alkythane 7500 finish is recommended.
- Excellent coverage with full opacity in only one coat
- Can be used at low temperatures
- Very tough
- UV resistant
- An economical coating to prevent corrosion
Remove oil, grease and all other contamination with ND14 Cleaner Degreaser or high pressure (steam) cleaning.
Remove rust scale, loose mill scale, loose rust and loose coatings by scraping and wire brushing, blast cleaning or sanding, followed by priming with the recommended RUST-OLEUM Primers.
Sand previous coatings in good condition to provide a key for adhesion and check compatibility.
The surface must be clean and dry during application.
Application and Thinning
Brush: Up to 10 vol. % with Thinner 633. Use natural long bristle brushes.
Roller: Up to 10 vol. % with Thinner 633. Use short pile, perlon 8 or mohair 4-6 mm rollers. Roller application may require 2 coats to achieve the recommended dry film thickness.
Air-atomised spray: 10 to 30 vol. % with Thinner 641. Gravity cup and pressure cup. Tip size: 1.0 - 1.5 mm Atomising pressure: 2 - 4 bar.
Airless spray: Up to 20 vol. % with Thinner 641. Pneumatic and electric airless equipment. Tip size: 0.009-0.013 inch Fluid pressure: 150 - 200 bar. Check wet film thickness to avoid excessive film build.
