INVENTING VISIONS FOR YOU.

5

As your leading partner for polyurethane chemistry,

we know you are competing in increasingly chal

lenging environments: Your customers are becom

ing more and more demanding in their expecta

tions for quality, durability, sustainability and

aesthetics of products. And they have more

choices. For you this means that cost pressure is

rising – while innovation cycles are becoming fas

ter and faster.

So what you are asking for quite rightly is to make

our invention power work for you – by improving

your productivity, driving sustainability, ensuring

reliability and cocreating future proof businesses.

Thus, we are committed to constantly search for

things that will make a real difference to you.

Things that will make your business grow, help

you drive profitability, make your solutions safer.

This we do with a very specific understanding of

innovation which we call inventing.

Inventing always starts with thinking about your

unmet business challenges. It requires an in

depth understanding of your needs along the

whole value chain – and building and fostering

close and trustful partnership with you. To make

sure: What we invent stands the test of time.

Living up to this aspiration needs more than com

petencies – it needs a corporate culture defined

and lived by dedicated people who share a set of

fundamental values. An attitude of openness that

invites you to cocreate new things – rather enab

ling you than just providing. An unrivaled perfor

mance orientation to constantly strive for the bet

ter, be it through big or small changes. A true

sense of business regardless of function. And a

deep commitment to delivering our promise every

day. Anywhere. Again and again.

INVENTING FOR YOU.

High coating performance –

enabled by nature

Sustainability drives innovation at Bayer. We

are committed to optimizing our manufacturing

processes, reducing the impact of logistics, and

enabling sustainability along the value chains.

Renewable feedstocks offer opportunities for

developing more sustainable building blocks for

coating solutions – with significant potential for

reducing the carbon footprint of end products

while also reducing our overall dependence on

fossil-based resources. But to make more sus-

tainable solutions not just possible but also

economically feasible, the performance of all

our feedstocks needs to satisfy high industry

standards. To this end, we are evaluating the use

of renewable raw materials and will enlarge our

product portfolio with new bio-based and mid- to

long-term cost-competitive products, provided

the raw materials become commercially available.

In all these efforts we are committed to focus-

ing on products that perform at least as well as

established products but are at the same time

more sustainable.

Outstanding quality and supply security –

worldwide

Bayer MaterialScience, the world’s leading manu-

facturer of aliphatic and aromatic isocyanates,

offers an extensive range of raw materials and

services for the coatings and adhesives industry.

This allows the very latest technology to be used

extremely effectively for a variety of applications.

Thanks to its unique setup and worldwide network

of state-of-the-art production sites, R&D facilities

and customer technical centers, industry-leading

supply chain setup, global orientation and local

stocks, extremely large product portfolio, highest

health, safety and environmental (HSE) standards,

as well as tailored supply chain flexibility with short

lead times, Bayer MaterialScience offers the indus-

try unrivalled supply security and assured quality.

Solutions to enhance your process efficiency

Nowadays, the quality demands made on indus-

trial processes are very high. But at the time,

there is a clear need to cut costs. Both goals can

be achieved by increasing process efficiency. At

Bayer we have a wide range of solutions designed

to enhance your process efficiency. Why not take

advantage of our know-how? These solutions will

be good for your bottom line.

Building blocks for supply security, efficiency and sustainability

thane coatings and adhesives, blocked polyiso-

cyanates for 1K polyurethane baking coatings

or hydrophilized polyisocyanates as crosslinkers

for water-reducible polyurethane systems, our

products come into play wherever crosslinking

is used to achieve high resistances and reliable

adhesion under efficient conditions. Our solutions

are in use today in a variety of applications, such

as automotive OEMs, automotive refinishing, and

coatings for wood, industrial goods and plastics.

They are also used in reactive adhesives, textile

coatings, and anticorrosion coatings.

Customized properties

Gloss, leveling, scratch resistance, hardness and

flexibility can be precisely adjusted by the choice

of polyisocyanate and polyol. Chemical resist-

ance, adhesion, light fastness and weather sta-

bility are additional properties that can be indi-

vidually adapted to your specific requirements.

Moreover, coatings with easy-to-clean, soft-touch

or reflow properties can also be produced through

smart formulations.

Flexibility in prepolymers

Our product range of prepolymers comprises aro-

matic and aliphatic NCO- and silane- terminated

products. These prepolymers make a wide range

of properties possible in coatings, adhesives and

sealants. The typical areas of application include

wood coatings, corrosion protection, floor coat-

ings, elastic adhesives in transportation, parquet

adhesives, engineered wood constructions, flex-

ible film lamination, and sealants. Prepolymers

with a low fraction of non-polymer-bound compo-

nents open up formulation options for producing

reactive polyurethane adhesive and sealants that

are not subject to labeling requirements.

Pioneering polyurethane chemistry

Ever since the discovery by Otto Bayer of the

poly isocyanate-polyaddition process in 1937,

Bayer has pioneered polyurethane chemistry. 50

years ago, Bayer developed the first applica-

tions using polyisocyanates for the coatings and

adhesives sectors. We work closely with our cus-

tomers to systematically advance the state of the

art in polyurethane technology. Using market-ori-

ented research and development, we specifically

adapt our product portfolio to our customers’

increasingly stringent requirements. Together with

you, we want to continue our successful journey

along this path.

Wide variety of applications

Our polyisocyanates comprise a broad range of

products for one and two-component (1K/2K)

polyurethane systems used in numerous applica-

tions. Whether as crosslinkers for 2K polyure-

Prepolymers are the reaction products of aromatic or aliphatic isocya-

of the isocyanate content and functionality enables the viscosity of the

prepolymers and the mechanical properties of the finished products to

be precisely adjusted.

At Bayer innovation is in our DNA. Ever since

Otto Bayer discovered polyurethanes in 1937,

we have been driving polyurethane innovations

in coatings and adhesives as well as in other

application areas. As our partner you enjoy fast-

lane access to polyurethane innovations, and

can help us in developing the next generation of

polyurethanes to meet the consumer electronics

industry’s upcoming challenges and needs. What

can we offer you?

• Powerful know-how on both established and

new polyisocyanates, as well as on new poly-

urethane hybrid technologies.

• The prospect of new application technologies

to enable efficient processes.

• More sustainable, biomass- or CO2-based

materials that do not sacrifice high performance.

Join us to shape the future!
