Frequently Asked Questions
For both products, H2OFF electric and H2OFF anticorrosion the maximum temperature at the time of the application must not exceed 35°C or the propane gas used as propellant in spray cans, could catch fire. The propane gas evaporates after a few seconds, therefore the H2OFF will retain its capacity up to a temperature of 140°C.
For special applications we can produce without propane gas canisters that have no risk of flammability.
The product sold in bulk or jelly cans may be applied to surfaces and objects up to 90°C
The minimum temperature at the time of the application should not be lower than -40°C, at very low temperatures the material flows with difficulty. After applying the H2OFF keeps its propriety up to -80°C.
The H2OFF electric can be applied on the electrical contacts that are subjected to high voltages of: 10 kV, 50 kV, 100kV and, if in these conditions, are protected from corrosion, oxidation and humidity?
Yes, even when subjected to high voltage it maintains its protective features against corrosion and humidity, in addition to his dielectric features reduces the risk of short circuit.
Note: H2OFF does not dry and does not become solid
The product protects the electrical equipment, the metal and the circuits from the effects of hydrogen sulfide (hydrogen sulphide in gas - H2S)
No, if you want to paint a surface treated with H2OFF is better to remove the H2OFF with a degreasing agent. It is possible, viceversa, to apply the H2OFF on a painted surface.
The paint will have many difficulties to dry because it will mix with the layer of oily H2OFF that do not evaporate or solidify.
Yes you can. The painted surface will be protected from moisture and corrosive agents.
Computers, cell phones and other electronic devices can be treated for corrosion protection and for electric insulation porposes but with some precautions regarding the protection of monitors and displays.
The H2OFF has an oily consistency so we recommend do not apply H2OFF on:
- Optical and camera lenses and other optical devices
- Display of mobile phones, PDAs and computers
Microphones, speakers, (these devices can be treated with H2OFF in their electrical parts but the vibrating membranes of loudspeakers and other audio devices can be damaged if soaked with the oils present in H2OFF).
- Optics for laser installations and video
- Do not apply to electrical components that have components in paper or fabric or other materials that can absorb the oils of H2OFF (some types of capacitors have these features).
Yes, the H2OFF is particularly suitable for this type of protection in outdoor environments and in case of rain. We recommend that you avoid coming into contact with vibrating membranes of loudspeakers and audio equipment.
The protection lasts from one to three years and depends on mechanical abrasion to which it is subjected the treated surface.
No, no negative effect or deterioration on metals, plastics, rubber, glass, paints, varnishes, ceramics, electric motors.
It limits the concentration of harmful substances and has been adopted by the European Union in February 2003. The Directive entered into force on 1st July 2006 and restricts the use of six hazardous substances:
4. Hexavalent chromium (Chromium VI)
5. Polychlorinated biphenyls (PBBs)
6. Polybrominated diphenyl ethers (PBDEs
Yes, H2OFF complies with RoHS 2002/95/EC.
The H2OFF is flammable in the version bottled in aerosol cans because the cans contain propane / butane as propellant gases. A few minutes after application the propane will evaporate and the H2OFF is no longer flammable.
For special applications and upon request we can produce the spray cans without flammable gas.
H2OFF packed in the jellycans do not contain gas and is not flammable.
Yes, The H2OFF coating protects for long periods from the corrosive effects of sea water, salts, acids and aggressive chemicals. The protective effect of H2OFF can be increased and prolonged with repeated applications.
The H2OFF electric has excellent dielectric properties and good anti-corrosion features.
The H2OFF anticorrosion has exceptional anti-corrosive features but no dielectric strength.
No, we do not recommend it because you lose the effect of the dielectric.
Yes, the H2OFF anticorrosion is ideal for the lubrication of moving mechanical parts.
No, the spray cans containing propane-butane (which are flammable gases) as propellant gas, therefore, the safety rules require that the electric current is disconnected. The propane / butane evaporate in a few minutes so 15 minutes after application you can replace the current.
For special applications we can produce, without propane gas, spray cans that do not have this limitation.
How do you explain two contradictory properties of the H2OFF electric protective coating? (At the same time it improves the quality of electrical contacts and the electrical insulation)
Indeed the coating of electric H2OFF has dielectric properties that increase the iinsulation and, at the same time, improve the quality of the electrical contacts.
Immediately after applying the protective coating has high dielectric properties, but not exceptional. After the application it cleans the surface, removes the moisture and form a protective flexible coating that does not harden with time.
Within 24 hours from application the properties of electrical insulation grow, increasing the insulation resistance of electric equipment protecting them from leakage currents and surface oxidation.
The "nanotechnology" products have also unique and special "mechanical" features.
The protective layer remains "soft" and "elastic" and when subjected to the normal pressure of a mechanical or electrical contact with a terminal its particles move by allowing the contact. The application of the electric H2OFF removes dust, dirt, oxidation and the water from the electrical contact improving its quality.
To better understand the better quality of electrical contacts coupled to the excellent insulation you can imagine a box filled with polystyrene small balls . With your hand you can go through the polystyrene and touch the bottom of the box, while you do this movement the polystyrene balls will move to allow the contact but all around the insulation will remain optimal. The nanoparticles move in a manner similar to the polystyrene balls.
