RUST PRIME

RUSTPRIME is an eco friendly brush/spray applied polymer based rust conversion primer incorporating highly effective oxygen scavenging agents.

When & Where do you need RUSTPRIME? Effective surface preparation is the key to successful performance of coatings and sand/grit/shot blasting is one of the most effective ways to prepare a substrate. Where blasting is not possible due to reasons like: Government Regulations :  prohibited/large requirement of compliances. Weather :   projects running through monsoon where surface & sand blasting media are wet for a long period. Quantum Of Work :   small equipments /single pipe lines/ erected structurals, etc. Operations : running plant, restricted / congested area for operation, chemical plants with requirements of flame proof operations / offshore. Rebars :  rusted due to prolonged external storage.

Steel always tends to form rust- its natural form of existence. Rust is always in the form of layers. Oxygen & moisture / water - causes & propogates rust. Rusting is a continuous dynamic process at two levels - at the surface : by continuous fresh intake of oxygen & moisture. - at the substrate : due to entrapped oxygen, water, dissolved salts. Complete removal of rust is impossible except by sand/shot/grit blasting

Basic Truths about Rusting

Why Conventional rust converters do not meet the above requirement?

They are phosphoric based which are technically rust stabililsers and not rust converters. They do not have the capability to penetrate through all layers and scavenge oxygen. Hence complete rust conversion is not achieved. They leave an acidic surface which hinders effective bonding of finish coats.

Should effectively tackle surface & substrate rusting. Should be capable of de-oxygenating at the rust-parent metal interface. Should give a neutral surface upon curing. Should be non toxic. Should be impermeable to further ingress of moisture & oxygen. Should convert rust completely.

How A True Rust Converter Should Work

The 4step Process

How does RUSTPRIME work? First - converts rust into stable ferro ferric complex. Second - Offers surface protection by forming an membrane impermeable to water / moisture & oxygen - agents causing corrosion. Third - offers substrate protection by penetrating to the bottom layer of rust, scavenging the oxygen and absorbing the moisture. Fourth - The impermeable membrane doubles up as an effective neutral primer to receive finish coats.

How you benefit from RUSTPRIME? Effective bond between concrete & Rustprimed rebar. Effective bond of finish coat paint to neutral Rustprimed surface Extends life of the protective paint film and steel structures thereby minimizing frequency of annual painting and hence saves costs. Rust is totally & completely treated.
