Chemtools R-70 is a chemically engineered, multifunctional formulation that provides unprecedented penetration, lubrication and unsurpassed corrosion protection to multi-metals.
R-70 has been specifically formulated for the electrical, telecommunication and electronics industry which normally requires unique solutions.
Electronic components are a complex assembly of metallic and non-metallic materials.
Given their complexity, there are many mechanisms by which corrosion of electronic components can occur.
- Pore and creep corrosion of base metals plated with a noble metal
- Corrosion caused by deposited pollutants in combination with moisture
- Fretting corrosion
- Localised and stress corrosion in the presence of corrosive contaminants (ie Chlorides),
- Galvanic corrosion resulting from contact of dissimilar metals
- Electrolytic corrosion resulting from applied potentials normally found in electronic devices
- Process control or similar applications for the electronics being operated in harsh industrial environment
- Atmospheric pollutants
- Low levels of contaminants present in packaging materials and as a result of human handling
A corrosion cell is similar to a tiny battery; there is an anode, cathode, electrolyte and a path of current.
User can eliminate any one of these elements and can shut down the corrosion process.
Upon application, R-70 revive-it eliminates two of those elements and that is even before the corrosion protection phase.
R-70 revive-it immediately eliminates two of the four corrosion causing elements.
Upon application to a metal surface (ferrous or non-ferrous), it displaces electrolyte then starts migrating into cavities and hard to reach areas, leaving a mono-molecular layer (ultra-thin film) that polar bonds to the metal surface and blocks the path of current.
R-70 revive-it also incorporates what is termed as Vapour-Phase Corrosion Inhibitor (VCI or VPCI). They are chemically engineered and designed to vaporise and carry the corrosion inhibitor pedigree into the surrounding atmosphere.
After the vapours have condensed to form a thin film of micro crystals, the inhibiting process continues.
In the presence of even minute quantities of moisture (surface or airborne), the crystals dissolve and develop strong ionic activity.
The result of such activity is absorption of protective ions onto metal surfaces, with the concurrent replenishing of the mono-molecular film to breakdown the contact between the metal and electrolyte.
The presence of this invisible mono-molecular film does not alter any of the important properties of the metal, even in precise electronic applications, where properties such as conductivity, magnetic permittivity or dimensional tolerances are critical and where even minute deviations could cause malfunctioning.
R-70 revive-it is not a sealant, contains no wax, tar, silicone or solids and once dried (approx 24 hrs - varies according to atmospheric conditions), it leaves no sticky, gummy mess behind.
Polar bonding of the ultra-thin film with the metal surface makes R-70 revive-it cling like a magnet. If the film is disturbed or scratched, capillary action and VCI activity will cause the film to self heal and replenish.
VCIs provide an effective means of protecting electronic components from corrosion.
These compounds have sufficient vapour pressures (103 to 105) mm Hg at 21°C to allow vaporisation and subsequent condensation and absorption on metal surfaces as a mono-molecular passivating layer
