Anti-stick-slip behaviour

Even under high area loads, SKC slideway coatings offer
a jerk-free starting and smooth movement. Minimum feed
(in the range of microns) and a very precise positioning
are achieved by SKC-coated guideways, if an adequate
drive, an adequate lubricating system and lubricant are
used. This behaviour is obtained by the most salient of the
positive properties: the static friction fo is smaller than the
kinetic friction fv.
Forming exactly to size and at low cost

SKC slideway coatings harden without any technically
relevant shrinkage, therefore the accuracy of the surface
to be formed is truly reproduced on the SKC antifriction
coating. So, in most cases, a subse-quent and costly
mechanical machining is avoided, as the lubrication
grooves can be formed simultaneously.
Resistance to wear

The excellent properties of the SKC compounds minimize
wear of the slideway coating and the opposing guide surface.
The readiness with which it embeds foreign bodies offers an
additional and an effective protection against scoring.
Damping

The high accuracy of SKC-coated guideways and the technological properties of the slideway coating allow
the minimum of guiding tolerance. The excellent damping
behaviour of slideways, e. g. compared to roller-type
guideways is therefore remarkably improved.
By the increasing frictional function in the boundary area,
and into the direction of motion, damping is given.
The dynamic rigidity of the machines is improved.
Safety and reliability

The excellent properties under emergency conditions of
the SKC slideway coatings avoid high wear, even under
unfavourable conditions, such as inadequate lubrication.
SKC-coated guideways do not “seize”.
Dimensional stability

IIn contrast to many other synthetics, SKC slideway
coatings are scarcely effected by deformation under load,
in particular, under the influence of heat (see tech. data).
Excellent adhesion

SKC slideway coatings adhere excellently on cleaned metallic
surfaces, and also on existing SKC layers. Correction of damage
or of machining errors on SKC slideway coatings can be done
easily. Even on components of machines made of solventless
polymerisable resinous compound or cement-bound concrete,
SKC slideway coatings have outstanding adhesion characteristics.
Chemical Properties

SKC compounds are resistant to water, sea water, mineral and synthetic oils, weak
acids and caustics, gasoline and alcohol.
They are not resistant to acetone, benzene, methanole, phenoles and cresoles
(under permanent load), and to solvents (under a longer-lasting influence).
Any particulars as far as chemical resistance is concerned have to be seen under
a certain reservation, as parameters like temperature, time of action and state of
hardening of the compounds are of importance. If there is any doubt, we recommend
to provide specific storing tests.
In cases of long-term influence under watery solvents, as well as by depositing of
oxydes, fission and metabolic products (especially from water-mixable
coolants/lubricants) dimensional variations of some microns might occur.
