Choke and carburettor cleaner

Why should a choke and carburettor cleaner be used to remove deposits? Can the deposits not be removed with petrol or kerosene?
Resins, carbon and other deposits formed in the intake tract cannot be washed off with petrol, because they precipitate out of petrol itself. A far stronger solvent is needed here. In addition, deposits and dirt are better washed off with a pressurised jet of cleaner, which is much more effective. In AXIOM^® choke and carburettor cleaner we use a strong solvent; in addition, we have selected the gas pressure inside the can and the diameter of the spray valve so that the jet is strong enough while the consumption of the product remains moderate.

Synthetic penetrating lubricant

What properties should a penetrating lubricant have?
The properties a penetrating lubricant must have are quite varied and some even contradict one another. For example, in order to provide good penetrating properties high fluidity is needed, whereas in order to provide good lubricating properties low fluidity is needed instead. It is also important that a penetrating lubricant displaces water and softens rust

Graphite grease

What makes graphite grease special?
The characteristics of graphite grease are determined by the properties of the graphite powder it contains. Graphite is distinguished by the fact that its molecules bond well to metal oxides and bond weakly to one another. Thanks to this, graphite creates a slippery film on the surface that withstands high loads and at the same time is not rubbed off the metal surface. Moreover, even if the grease begins to break down under the action of high loads and temperature, the graphite remaining on the surface of the rubbing parts continues to perform its function, acting as a dry lubricant. Graphite grease can therefore act both as a separating lubricant, preventing parts from “sticking” to one another, and as a friction lubricant, significantly reducing the friction force between parts. Because graphite holds well on the metal surface and has dirt-repellent properties, the grease also creates a kind of anti-corrosion coating, protecting the surface from atmospheric influences. Graphite has high electrical conductivity, so graphite grease can be used to protect battery terminals from corrosion without fear that the grease itself will create high electrical resistance.

Varnish for battery terminal protection

Why do battery terminals need to be protected?
Oxidised battery terminals look untidy. But it is far more unpleasant that corrosion penetrates the contact patch between the battery terminal and the cable connected to it. As a result the effective contact area is reduced and the electrical resistance grows. This creates an increased load on the vehicle’s electrical equipment, in particular on the alternator, leads to undercharging of the battery and, at high electricity consumption, causes severe heating of the terminals. But the most important thing is that poor contact between the terminals leads to a significant drop in the starting current, and when the engine is being started the battery simply cannot deliver all the necessary power through the poor contact.

Aluminium anti-seize lubricant

What are the main requirements for an aluminium anti-seize lubricant?
Such a lubricant is called a separating lubricant and its main purpose is to ensure reliable separation of parts that are in contact with one another under high forces, at high temperatures and under the action of aggressive media, for example road chemicals. At the same time the relative movement of the parts themselves may be very small (brake pad and caliper)

High-temperature copper grease

Why is low flow when heated important for high-temperature lubricants?
One of the main properties of high-temperature lubricants is the ability to keep their consistency when heated, without thinning and running out of the friction zone. Cheap imitations of high-temperature lubricants are made by mixing a grease such as «Litol» with copper powder.
