Bayer MaterialScience also stands for the know-how and expertise of its employees all over the world. With growth products, excellent technologies and a well-stocked innovation pipeline, Bayer MaterialScience aims to extend its market leadership. In pursuing this goal, our employees, society as a whole and the environment are accorded just as much importance as the well-being of the company. Material: The materials we develop. For new products and new markets. With our expertise as innovator in polymer materials, we know how to turn innovations into real-world applications for our customers. Science: The knowledge on which our work is based. Our intuitive feeling for research with perspective has developed over several decades. Together with a global network of interdisciplinary thinking, it provides the driving force for leading-edge, innovative and sustainable solutions. The Coatings, Adhesives, Specialties Business Unit (BU CAS) offers a comprehensive range of raw materials for system solutions in these sectors. Our products are based primarily on polyurethane chemistry. Its outstanding expertise and long years of experience make Bayer MaterialScience one of the world s leading suppliers in this field. CAS raw materials are used in wide range of applications. Products formulated with these materials protect aircraft, railcars, ships and even oil platforms against the effects of weather and corrosion. They also help ensure that red wine, cleaning agents and other attackers cannot harm furniture or parquet flooring. CAS raw materials can even be used to provide concrete with lasting protection against abrasion and weathering. Another area of application for BU CAS products is the formulation of adhesives, in particular in the shoe, furniture, automotive and construction industries. We also offer sealant raw materials for use primarily in the construction industry. gic segments: Polyisocyanates and Prepolymers, Dispersions and UV systems. In each of these segments, customers can benefit from our wide-ranging experience and long-standing know-how. For us as technology leaders, the development of innovative solutions for and with our customers is one of our core competencies. Thanks to our great innovative strength, we are not only naturally focused on the demands of existing markets, but also want to create and tap into new markets. Our success in this respect is based on intensive research work in our own modern laboratories and constant dialogue with our customers. Even though we discovered polyurethanes and are the technology leader for polyurethane-based coatings and adhesive raw materials, we are constantly working to expand and improve our unrivalled expertise. We are wholeheartedly committed to developing solutions for and with our customers, and to delivering tailor-made products and pioneering process innovations. In all the activities of the Coatings, Adhesives, Specialties Business Unit (CAS), the customer is key.

4 P O L Y I S O C Y A N A T E S A N D P R E P O L Y M E R S : GRADES WITH SHINING PROPERTIES A P P L I C A T I O N S HIGHLIGHTS Innovation is our tradition. With the breakthrough discovery of the polyisocyanate-polyaddition process 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 continue 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 applications. Whether crosslinkers for two-component polyurethane coatings and adhesives, blocked polyisocyanates for one-component polyurethane baking coatings or hydrophilized polyisocyanates as crosslinkers for water-reducible polyurethane 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 applications, 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 resistance, 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 prepolymers properties of coatings, adhesives and sealants can be varied over a wide range. Typical areas of application include wood coatings, corrosion protection, floor coatings, elastic adhesives in transportation, parquet adhesives, engeneered wood construction, flexible film lamination and sealants. Prepolymers with a low fraction of non-polymerbound components open up formulation options for the productions of reactive polyurethane adhesive and sealants, that are not subject of labelling requirements.

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 user s products. This especially applies to green house gas emissions, health protection and energy consumption. We focus our developments on advanced product technologies that are safe in their application and environmentally friendly: waterborne products, solvent-free products and those with a high solid content. The emphasis here is on products with a very low rate of residual monomers or volatile substances. Our product range already included products based on biomaterials and we are now investigating the potential of renewable resources for new high-performance products while also taking ethical standards into account. In production our priority is on occupational health and safety as well as energy- and resource-saving processes. Our main aim is to conduct our business successfully 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. Our global presence also means local presence. You can rely on us wherever in the world you are thanks to our global supply chain management. With production sites in most of the world's strategically important regions we aim for short lead times and short routes to your production site. Our quality, fast application support and expert advice are available to you wherever you are. Success is also dependent on the right timing. Speed, flexibility, fast development in response to market requests, efficient production and delivery we will help you to deliver these crucial factors. Because your success is ours as well.
