Chain oils
Chains are running under mixed friction, therefore the reduction of friction and wear are essential requirements to the lubricant.
Not the lubricants which adheres on the surface of the chain is responsible for good lubrication, but the inside lubrication is important.
This means that the oil must offer excellent creeping properties. Only best adhesivon of the oil allows extended cycles of re-lubrication. Furthermore it provides good corrosion protection and is a condition for low oil consumption.
Natural adhesion in view of the polar properties avoids dripping and centrifuging of the oil and minimizes dust absorption.
The oil structure and additives - with or without solid lubricants - are especially tailored to special applications.
