- Implementation standards：
Where to use
It can be widely used in metal roofing needs excellent protection, steel structures, bridges, ships, containers, tanks pipes, shore installations, structures and galvanized aluminum and other corrosion underlying process.
▶water-based environmentally friendly products,no solvent pollution, non-toxic, non-flammable non-explosive.
▶ superior resistance to salt spray, acid and alkali resistance.
▶ excellent weather resistance, anti-stain and anti-UV properties,less maintenance and lower maintenance.
▶Coatin has strong adhesion,film excellent water resistance, when encountering water, not soft, do not return to rust.
▶ Unique characteristics of the water-curable, after 30 minutes surface drying, even in water environments can cure properly
▶ open bucket ,used at once, the construction is simple and convenient.
Appearance: light grey (the color can be customized）
Solid content: 55% ± 2%
Fully dry curing
The shortest accordance with intervals
NOTE: on an inert substrate, One coat conditions at a thickness of 50 microns (air circulation, temperature, film thickness, and other factors will affect the drying time)
Construction should choose sunny, ambient temperature should be in the range of 5-40 ℃, relative humidity below 85% preferably,not be below 5 ℃ construction.
▶Should clean up the water, sand lime, welding slag, oil, thick loose rust, old patent leather, cold-rolled steel top anti-rust oil on metal substrate surface.If necessary, use our W305 environmentally efficient primary treatment coating on the metal substrate corrosion to rust and anti-rust treatment,that can eliminating the need for sand blasting, shot blasting, grinding rust and other complex processes.
▶Construction W303 topcoat coating should conduct after coat W302 fully drying.
1.Coating W302 metal roofing antirust paint on the treated base(coating amount of 10m2 / KG)
2.undercoat an anticorrosive metal roofing W303 after two hours after the surface hardening again coated with (coating amount of 10m2 / KG)
3.to make the roof waterproof further,wnen Rust-proof coating Overall construction is completed and through 72 hours after hardening,can use our company special metal roofing waterproof coating for waterproofing construction of node location.
