Stahl provides an overview of its sustainability initiatives and new product lines. It discusses its six steps towards a more sustainable future in raw materials, production, packaging and distribution, product application, product use and maintenance, and end of life. It highlights its new Polymatte line which uses crop-derived polyols to reduce the product's environmental impact. Stahl also introduces its STAHL EVO range of next-generation polyurethane coatings and PermaQure base which contains no volatile or toxic components. Finally, it discusses its portfolio of polymers, crosslinkers, and additives to optimize coating performance and stability.

3. Sustainability

4. Stahl strongly believes in taking responsibility.
We see it as an obligation to take a leading
role in creating a more sustainable future.
We believe, we have to use our innovation
power to reduce the impact on the environment
in each stage of the supply chain.
Stahl sustainability principle

5. Six steps
towards a more
sustainable
future

13. Unique
Carbodiimide
Crosslinkers for
improved chemical
resistance

14. To improve physical and chemical properties of your coatings and lacquers,
Stahl offers Crosslinkers. Stahl offers VOC-free and isocyanate-free
Crosslinkers. This patented technology is used worldwide to formulate high
performance and more sustainable coatings and lacquers.

16. I imagine smooth and
gentle surfaces with
improved sustainability
If it can be imagined,
it can be created

17. How can something so
dull be so exciting?
Polymatte®

18. Polymatte® gives an optimum matt finish
that gives the total haptic and aesthetics
required and desired by consumers.

19. This Polymatte® surface shown is one that is
based on a unique continuous morphology
made-up from (semi-)spherical PUR particles
that are inherently created during film
forming of the polyurethane coating.

20. We imagined smooth and gentle surfaces
with improved sustainability. For our Green
Polymatte® we use a Polyol that is derived
from oil that come from farm crops cutting
the cycle down to a few months.

21. The Polyol is derived from rapeseed
that is mainly cultivated for animal food.
The rapeseed Stahl uses can be sourced
locally so a reduction in transportation of
the raw materials benefits the environment.

22. I imagine high
performing coatings
produced in harmony
with the environment
If it can be imagined,
it can be created

23. Lowering the environmental impact of products is a priority for brands in
apparel, home furnishing, automotive and industrial application. To support
these brands, Stahl developed the extensive STAHL EVO range consisting of
the next-gen polyurethane coatings for footwear, bags, garments, upholstery
and car interiors.

25. The STAHL EVO base is the more
sustainable alternative for the
traditional coagulation base thanks to
the Permutex® mechanical foam.
Permutex® RC foam compounds are
ready-for-use and result into
consistent application with high
performance. Permutex® mechanical
foam can be used in transfer coating
or as direct coating on textile.
Permutex®

26. PermaQure®
The patented PermaQure® EVO base evolved
out of classical high solids polyurethanes.
PermaQure® products contain no volatile
components at all and are therefore free of
odour and emissions. Different from classic
high solids, PermaQure® does not contain
toxic blocking agents like Mekoximes. It
provides a thick and durable coating layer
with excellent hydrolysis resistance and
can be compact or foamed. PermaQure®
is specially designed for the transfer
coating process.

28. Polymers
Our Permuthane® and Permutex®
polymer portfolio offers water-based
and solvent-based urethanes based
on different polyols and diisocyanates:
1. Aliphatic or aromatic diisocyanates
2. Polyether, polyester or polycarbonate
polyols

30. Additives for optimal
line performance
and stability

31. Our portfolio offers an extensive variety of polymeric
binders and finishes. At the same time, the right
processing and application characteristics of
lacquers and coatings make it difficult to rely on
general purpose products. Therefore we created a
comprehensive range of additives. To optimize line
performance and stability of both waterborne and
solventborne lacquering systems and to enhance
specific surface coating properties.
Additives for optimal line
performance and stability
Our range
■ LA: Levelling agent
■ RM: Rheology modifier (thickener)
■ DF: Defoamer
■ HM: Hand modifier
■ MA: General additives
■ WD: Waterborne duller
■ SD: Solventborne duller

32. We work together with our partners to provide them with
the best possible solutions in process chemicals for
leather products, performance coatings and polymers
If it can be imagined,
it can be created

33. We believe that if it can be imagined, it can be created
