3 The story behind the modular raw material concept Perfectly matched raw materials The existing configuration raw material supplier coatings formulator faces a situation where balancing of technical performance, innovation of products and economic efficiency turns out to be increasingly difficult. Current coating formulations are containing numerous different raw materials that exhibit a multitude of chemical as well as physical interactions. Synergistic as well as antagonistic interactions affect manufacture, application as well as the final performance of the corresponding coating. New level of product performance Only a detailed knowledge of the chemical design of raw materials allows for precise control of physical as well as chemical interactions. As a matter of fact, this opens the door for substantial performance increase of formulations and coatings. Outstanding batch to batch consistency A combined expertise of the members of our raw material network enables the development of modular, semi finished goods with harmonized chemical design delivering outstanding performances. Therefore a joined development between coatings formulators and our modular raw material network not only leads to more efficient and shortened development cycles but opens up the opportunity to excellent performing coatings with consistent outstanding quality. Quick & simple manufacturing All "easy to process" modular recipes are aligned to an optimum interaction of different chemistries in order to receive the best performance possible. The perfect match of all raw material modules allows an extremely simple and quick manufacturing practice. Better working environment The use of modular raw materials not only leads to a reduction in production costs and stockkeeping of singular raw materials but also helps to reduce waste and dust generation in production and improves working conditions in production without extra investments in safety equipment. In this context the modular raw material network has jointly developed a couple of high performance modular recipes for various applications. page 3 of 16
