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.

Desmoseal® S are silane terminated polyurethanes (STPs) which com-

bine properties of polyu r e thanes with those of silicones to give a new

class of prepolymers. These prepolymers are primarily designed to act

as binders for moisture-curing sealants and elastic adhesives. They are

high molecular weight prepolymers consisting of a polyurethane-back-

bone and a trifunctional silane end group.

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.
