A hundred-year balance Annual Report 2010 - Uzin Utz AG

for foot traffic and loading. Thanks to the low application
quantity, the impression characteristics are reduced to a
minimum. The newly developed adhesion fixative for design
coverings differs from existing competitor products
due to the significantly better application properties and
a longer open time. The development specialists have
also formulated a new universal fixative tailor-made for
the local requirements in the eastern European market.
The newly developed product UZIN U 500 has been designed
as a special fixative for this market, and has the
decisive advantage over local competitor products that
PVC and CV floor coverings in residential applications
can be laid easily and cost-effectively by rolling the fixative
onto different substrates, with correspondingly
low material consumption.
c) Products for special applications
The polyurethane levelling compound UZIN KR 410 has
been upgraded to very low emission levels by extensive
re-formulation work, and now complies with the best
Emicode class EC 1 R Plus. The optimised product has
also been given better coverage, the trowel application
has been made easier and the surface finish looks much
more homogenous. A new fibre-conductive dispersion
adhesive has also been developed for industrial applications.
UZIN IN 19458, an adhesive for PVC, rubber and
textile floor coverings, is outstanding particularly for
its high initial conductivity and its excellent adhesion,
particularly in combination with floor coverings with a
high softener content on double floor panels with metallic
and mineral substrates.
d) Parquet laying materials
As announced, Uzin Utz AG discontinued the sale of solvent-based
parquet adhesives for the German market at
the beginning of 2011. Not only for this reason was it that
the focus remained heavily on the parquet area again in
2010. A whole range of ground-breaking new laying materials
were developed. The first of these that should be
mentioned is the group of moisture-hardening 1-K parquet
adhesives which are both solvent-free and waterfree,
and on the basis of information recently published
by the “Berufsgenossenschaft Bau” (“Building Trades Association”)
can now be officially classified as substitute
materials for solvent-based parquet adhesives. Uzin
Utz AG has for years produced parquet adhesives whose
serration hardness is unique in the market. UZIN MK
95, an innovation in polyurethane adhesive technology,
was unmatched for a long time, and was also not surpassed
by the silane-terminated adhesive UZIN MK 100,
since adhesives with silane adhesive technology usually
demonstrate a lower performance range in this respect.
They could however compensate for minor disadvantages
of polyurethane technology, such as perhaps the more
difficult and complex application. Intensive efforts were
therefore devoted to combining the best properties of
both adhesive technologies. The adhesives experts solved
this problem in an impressive way with the development
in 2010 of a new silane-terminated polyurethane
adhesive. A new era in parquet flooring has begun with
the new product UZIN MK 200. It combines the longproven
polyurethane technology with the technical work
safety advantages of silane technology. Through the use
of a new hybrid bonding agent technology, the R&D Fluid
Products specialist department has solved the problem
of how to bring the strengths of two technologies
down to an outstanding common denominator using a
modular design principle. The result is the first 1-K silane-terminated
adhesive with a hard-elastic and simultaneously
fast-setting adhesive serration. Its relatively
high serration hardness is almost equivalent to that of
1-K polyurethane adhesives, although the product still
has excellent spreading properties. The moisture-hardening
1-K silane-terminated adhesive is characterised by
the following plus points of the completely new standard:
Firstly, the hard-elastic adhesive serration with very
high shear strength and very good spreading properties,
and secondly the extremely fast drying properties with
simultaneously long open time. The parquet layer thus
receives a product which is extremely easy to apply and
lay, which greatly restricts wood deformation and joint
formation, and allows him to sand the surface after only
12 hours. This solvent- and water-free adhesive is approved
for all parquet types and formats. Following successful
emission testing, the new product has been classified
in the best Emicode class EC 1 R Plus.
» In addition to this work, the development of a special
product for the export market was successfully completed,
and the solvent-free dispersion parquet adhesive
UZIN MK 61 prepared for its forthcoming market launch
in 2011. In the reporting year, the important tasks of the
R&D Fluid Products specialist department included not
only the development of new products, but also the qualitative
further development of existing products. The
