Float glass is produced all over the world. Storage and transport conditions depend on the local conditions and influence the corrosion state of the glass. On the other hand, the glass surface more and more becomes the substrate of high sophisticated functional coatings. As a consequence, a perfect glass surface is decisive because even smallest corrosion defects can spoil the end product. Different chemical / physical methods will be reported which characterize the state of glass surfaces freshly produced and after storage. A discussion will follow regarding the minimum needs of further processing of glass. Furthermore, test methods to simulate glass aging will be on focus. Dr. Emonds will give basic information regarding the chemistry of (glass) washing compounds. The technical needs for an optimal washing machine will be described as well as the proper maintenance of the washing circuit. Different concepts of corrosion protection are discussed. Special attention will be paid to anticorrosion interleaving powders and to liquid anti-corrosion products. The positive influence of anticorrosion products on low-e coating will be demonstrated. A major problem in corrosion protection is the proper application of anti-corrosion products. Mr. Senft will talk about different application possibilities and their advantages/disadvantages.
