4. Size coat
The size coat supports the base coat in the anchoring of the grit
on the backing and against forces which affect the grit during
grinding. The cover bonds are produced exclusively from resin
and also provide the product with its typical colour (exceptions are
coated abrasives with additional coats).
5. Special coats
Special coats with grinding aids provide the grinding tool
properties that positively affect the grinding process and extends
the service life of the coated abrasive. Special coats are applied as
an additional layer.
Stearate coat:
The stearate on a coated abrasive prevents the clogging and loading
of the belt and is specifically suited for high quality varnish surface
applications. Paints, varnishes and plastics can become soft and
sticky through the heat generated from grinding, this can result in
the premature clogging and loading of the belt. The dust clogs the
space between the grits and this can result in additional “negative
bond“. This clogs the grits and the sharp edges are no longer effective.
To prevent this from happening or to slow the process down, the
coated abrasives can be coated with a non-stick material, so-called
stearates.
Multibond:
The multibond, like the stearate coat, is applied in an additional
production step to the cover bond layer. This allows the cool grinding
of stainless steel and high alloy steels, which in turn increases the
stock removal rate and service life.
ACT – Advanced Coating Technology:
Klingspor uses this technology to improve the properties of the coated
abrasives. When working on metal, ACT provides significantly higher
grit adhesion, e.g. for aggressive belt grinding of the edges of
punched parts and castings. This significantly increases the life
of the grinding belt. For belts that are used for wood and varnish
grinding, ACT prevents the premature clogging of the coated abrasives
and significantly increases the service life.
Antistatic:
Electrode migration is the result of friction i.e. grinding between
different materials, and in turn causes charge separation, which in
the case of non-conductive materials, such as wood, results in
the load differences not being balanced. In these cases, the coated
abrasive is equipped with anti-static properties that ground the
electrical charge through the coated abrasive and the machine.
This prevents the grinding dust from adhering to the workpiece,
belt and machine.
