Rust-Steel  -  Rust Conversion Coating

Application:

Rust-Steel a metallic phosphate & chromate salt being used to convert rust and ferrous metal to continuous anti-corrosive membrane in order to protect the substrate from galvanising corrosion and enhance adhesion properties of the paint top-coat. By the chemical reaction, the neutral passive layer formed as an intermediate metallic forming layer. The formed porous capillary dried layer will absorb more portland cement solution (portlandite) into them and so enhance highly protective properties of the passive layer for reinforcement construction steel.

As a acidic water soluble, Rust-Steel could be applied by spraying, brushing, rolling...

Beside the capacity of converting rust and ferrous substrate to inert anti-corrosive membrane, it could be used to react with zinc metal top-coat (as zinc galvanised, hot-dipping zinc metal, melted sprayable zinc metal...) to form intermediate metallic layer enhancing paint top-coat adhesion into zinco-metal substrate.

This multi-purpose chemical converter could be applied in such application as below:

v  Temporally anti-corrosive for ferrous substrate for painting applicable in shipbuilding, construction steel... by protecting the ferrous metal from rust development and adhere well on substrate surface.

v  Forming passive layer on reinforcement construction steel to protect the substrate from galvanising corrosion and well combination of the cementitious portlandite ingredient to form unique and compact concrete-steel bonding layer.

v  Forming intermediate bonding layer to enhance the best adhesion of paint top-coat to zinc-metal.

v  Forming capillary metal layer, allows lubricating and preservative oil & fat to absorb better onto the metallic surface enhancing the protective capacity applicable in OEM industry.

v  Forming high electro-resistance membrane, app. 6x107 W/cm, reduce the surface conductive capacity of the metal substrate.
