Science for a better life
The 150th anniversary of Bayer AG is an occa-
sion to celebrate innovation and quality. What
started as a dyestuffs factory in the Barmen
district of Wuppertal is now a global corporation
with more than 110,000 employees. Although
that sounds like tradition and continuity, it is a
success story about change. The spirit of inven-
tiveness and the will to succeed form a bridge
spanning the company’s history from its origins
150 years ago to today.
In the beginning there was a friendship between
two men, plenty of a researcher’s natural curios-
ity and two kitchen stoves. On these, business-
man Friedrich Bayer and dyer Johann Friedrich
Weskott conducted experiments and eventually
discovered how to make the dye fuchsine. In
1863 they established the “Friedr. Bayer et.
comp” company.
Bayer products today help to improve the quality
of life for people and animals. One example is the
pain reliever Aspirin™, which came on the market
in 1899 and remains one of Bayer’s top products
to this day. When Bayer started selling Antinonnin,
the world’s first synthetic insecticide for control-
ling the nun moth, in 1892, it was the start of the
success story that is now Bayer CropScience. In
the area of high-performance materials, the poly-
urethanes for foams discovered in the 1930s and
the high-performance polycarbonate (Makrolon™)
patented in 1953 are the foundation for an ever-
expanding range of applications. These include
lightfast polyurethane coatings, made possible by
the Desmodur® N family of crosslinkers invented
by Dr. Kuno Wagner, and raw materials for the
production of anti-corrosion coatings for ships,
aircraft and automobiles.
Today, high-performance materials from Bayer
MaterialScience make an important contribution
to conserving fossil resources. It is thanks to the
invention of aliphatic polyurethane coatings that
assets can be preserved for longer than ever
before. Modern coating systems withstand both
wind and weather, impart durability and a glossy
finish. At the same time, Bayer MaterialScience’s
production technologies set standards in safety,
quality and cost efficiency. A continuous flow of
new innovations that benefit both society and
the environment provides for sustainable growth.
In this way, our products live up to our mission,
Bayer: Science for a better life.

CAS BuSINeSS uNIT
Leading in polyurethanes
The Coatings, Adhesives, Specialties (CAS) Busi-
ness unit is characterized by its broad range of
products and many years of experience in re-
search and development. On this foundation,
CAS takes a leading role in polyurethane raw
materials, such as isocyanates and polyols, in-
cluding modified systems such as polyurethane
dispersions, silane-terminated prepolymers and
blocked isocyanates.
Products manufactured from CAS raw materials
are used, for instance, to coat buses, trains and
ships. They have an extremely long shelf life and
offer good weathering and corrosion protection.
For this reason, they also are critical in the man-
ufacturing of wind turbines, pipelines and steel
structures.
Our raw materials also serve various purposes
in the timber processing industry. In paints and
coatings they protect against discoloration and
wear. Adhesive raw materials likewise are used in
this segment, although they further are involved
in the production of shoes and motor vehicles,
and in the building industry.
In the field of specialty chemicals, we produce
premium polyurethane dispersions, e.g. for cos-
metic formulations and hydrophilic prepolymers
for medical wound dressings or functional films.
Cast elastomers represent the latest addition to
the product range.
Apart from the conventional fields of applica-
tion, the CAS business unit continues to develop
its portfolio of products and system solutions
toward new, lucrative market segments. These
efforts are supported by the quality and versatil-
ity of aliphatic polyurethane systems. examples
include encapsulation materials for light-emitting
diodes and solar systems, or moldings for opti-
cal and transparent applications.
At the center of all our activities are our custom-
ers. Be it polyisocyanates, prepolymers, disper-
sion polyols or uV systems, they can profit from
our many years of experience and the wealth
of knowledge of our experts. At the same time,
close collaboration with our customers is essen-
tial to the development of innovative solutions
and new markets.
Most of our efforts in this connection are put into
eco-friendly coatings that go easier on resources
and are efficient in application. We therefore fo-
cus on low-solvent, solvent-free or waterborne
systems. To improve our adhesives product port-
folio, we also target ecologically compatible and
user-friendly systems.
This makes it possible for us not only to meet the
demands of existing markets, but also to devel-
op new markets offering promising opportunities.
Our success along the way is based on intense
research in our own laboratories and continuous
dialog with our customers.

polyurethane coatings and adhesives, blocked
polyisocyanates for one-component polyurethane
baking coatings or hydrophilized polyisocyanates
as crosslinkers for water-reducible polyure-
thane systems: Our products are used wherever
crosslinking is used to achieve high resistances
and reliable adhesion under efficient conditions.
Our solutions are in use today in a variety of appli-
cations, such as automotive OeM and refinish
and the coating of transportation vehicles, wood,
industrial goods and plastics. They are also used
in reactive adhesives, textile coatings and anti-
corrosion coatings.
Gloss, leveling, scratch resistance, hardness and
flexibility can be precisely adjusted by the choice
of polyisocyanate and polyol. Chemical resist-
ance, adhesion, light stability and weatherability
are additional properties that can be individually
adapted to the respective requirements. With a
bit of clever formulation, coatings with easy-to-
clean, soft-touch or reflow properties can also
be produced.
Our product range of prepolymers comprise
aromatic and aliphatic NCO-terminated as well
as silane terminated products. With these pre-
polymers properties of coatings, adhesives and
sealants can be varied over a wide range.
Typical areas of application include wood coat-
ings, corrosion protection, floor coatings, elastic
adhesives in transportation, parquet adhesives,
engeneered wood construction, flexible film lami-
nation and sealants.
Prepolymers with a low fraction of non-polymer-
bound components open up formulation options
for the productions of reactive polyurethane adhe-
sive and sealants, that are not subject of labelling
requirements.
Innovation is our tradition. With the breakthrough
discovery of the polyisocyanate-polyaddition pro-
cess in 1937 by Otto Bayer, Bayer became a
pioneer of polyurethane chemistry. 50 years ago,
Bayer AG developed the first applications using
polyisocyanates for the coatings and adhesives
sectors. Polyurethane systems – also known as
“DD coatings” – have established themselves in a
number of applications. We work closely with our
customers to systematically advance the state of
polyure thane technology. using market-oriented
re sea rch and development, we specifically adapt
our product portfolio to the increasingly stringent
requirements of our customers. We want to contin-
ue our successful journey along this path with you.
Our polyisocyanates comprise a broad range of
products for one and two-component (1K, 2K)
polyurethane systems used in numerous applica-
tions. Whether crosslinkers for two-component

Prepolymers are reaction products of aromatic or aliphatic isocyanates
and polyols such as polyethers or polyesters. Due to the wide variability
of the isocyanate content and functionality, the viscosity of the pre-
polymers and the mechanical properties of the finished products can
be precisely adjusted.

Desmodur® and Desmoseal® M prepolymers are the reaction pro-
ducts of aromatic or aliphatic isocyanates and polyols such as poly-
ethers or polyesters. Due to the wide variability of the building blocks,
isocyanate content and functionality, the viscosity of the prepolymers
and the mechanical properties of the finished products can be pre-
cisely adjusted.

Sustainability @ CAS
Bayer is committed to the principles of
sustainable development.
We want to fulfill this commitment in three areas:
products and innovations, business practices and
corporate social responsibility.
Innovations are the driver of sustainability in the
CAS Business unit. Our raw materials make more
sustainable and durable solutions possible in our
end users’ products. This applies especially to
greenhouse gas emissions, health protection and
energy consumption.
In production our priority is a high standard of
occupational health and safety as well as energy-
and resource-saving processes. We focus our
developments on advanced product technolo-
gies that are safe in their application and provide
economic and ecological advantages over the
whole value chain from raw materials through
processing to the end-of-life. The emphasis is on
waterborne products, solvent-free products and
those with a high solids content.
We are investigating the potential of renewable
resources for new high-performance products
while also taking ethical standards into account.
Our main aim is to conduct our business suc-
cessfully and sustainably. For us this means
achieving commercial success on the basis of
sound business models and in a way that is
compatible with the needs of our employees and
society, protects the environment and preserves
our natural resources.
