Colour marking of the wood is one part
of many in the harvesting process
As colour marking is the foundation for
delivering the right products to the sawmill and
to minimise wastage, it is important that the
paint is of the right quality. Komatsu CM has
shown many advantages over competing brands
in performance tests.
Colour marking facilitates the handling of
the processed wood and is a prerequisite for the
correct product being delivered to the sawmills.
The quality of the paint is also an important
prerequisite for this process to go smoothly and
that no wood will go to waste.
An important factor is the colour intensity,
where alcohol-based paints have a relatively
low intensity while glycol-based paints have a
medium intensity - both types, however, have
problems with the colour spreading easily over
the cut surface. Komatsu CM on the other hand,
which is a water-based product, has a high
intensity while the paint does not spread over
the cut surface. This leads to clearer and more
visible markings that help the operator while
reducing colour consumption.
Something that can affect the final price of
the product is if the paint has penetrated the
wood and thus destroyed parts of it. Paint based
on both alcohol and glycol have problems with
the paint easily penetrating too deep into the
wood, causing a lot of wastage for sawmills.
Komatsu CM only adheres to the top layer of the
wood, about 2-4 mm, resulting in a better end
product. Another advantage is that Komatsu CM
does not cause any corrosion, which is usually a
problem with alcohol and glycol-based paints.
For both the environment at large and the
operator’s work environment it is very important
what the paint consists of. Glycol is hazardous
to health while methanol belongs to the group
of chemicals that are toxic alternatively can
cause serious or long term health damage.
Komatsu CM, on the other hand, is water-based with additives used in the food industry. It lacks
warning signs all together and is completely
harmless to humans and to the environment.
Overall, the tests show that Komatsu CM
has great advantages in terms of quality and
environment. The characteristics of the paint
mean that consumption is lower compared to
other brands, while improving the performance.
In conclusion, Komatsu CM provides a good end
product, something that both operators and
machine owners as well as sawmills profit from.
