This solvent-free one-component inorganic rust-prevention and corrosion-prevention coating with reducing function converts red rust to black rust(magnetite:Fe3O4)
Prevent CR Cera is a solvent-free one-component inorganic rust prevention andcorrosion prevention coating. It prevention rust layers of steel, converting red rust into chemically stable black rust(magnetite:Fe3O4). It exhibits superb film properties characteristic of inorganic systems, including weather resistance, heat resistance, adhesion, chemical resistance, water resistance and salt water resistance.
- Storage tanks, piping and other equipment in oil, gas and chemical plants. It is particularly effective in preventing salt damage.
- Corrosion prevention for any iron and steel materials, including those utilized on transmission towers, power plants, bridges, and metal roots of factories and gymnasiums.
- Maintenance and repair of hot-dip galvanized steel.
- Prevention of corrosion due to salt on ships, harbor facilities, etc.
Safe working environment
It contains no heavy metals such as lead and chrome.
It is solvent-free. It contains no organic solvents such as xylene and toluene.
It simplifies de-rusting work and significantly reduces dispersion of dust.
Addition of rust conversion function
It has an added function of easily penetrating into rust layers of steel and converting rust into chemically stable magnetite(Fe3O4). With this function its corrosion prevention is significantly higher than conventional rust inhibiting coatings.
Weather resistance and heat resistance
As it is an inorganic coating(film of alkoxysilane compound and –Si-O-Si-O- bond), it exhibits excellent performance in weather resistance, heat resistance, water resistance, durability and chemical resistance after curing.
Simple surface preparation and good performance in adhesion and rust prevention
Simple surface preparation of type 3 is needed.(treat the entire surface with the tool to remove degraded film. Remove loose rust from iron substrate with wire brush. Carefully remove oil and dust.) Prevent CR Cera forms an inorganic film with good adhesion and rust prevention.
Free of lifting(separation between substrate and old coating)
Conventional coatings contain a significant amount of strong solvent for better workability. However, during curing of the film the solvent evaporates, causes shrinkage of the pure coating film, and this tends to dissolve old coating film. This phenomenon is called lifting of the old film. Prevent CR Cera is free from lifting.
The process and the duration of repair work on a conventional heavy duty coating can be shortened.
