Rheological properties of thermoplastic polyurethane adhesive solutions containing fumed silicas of different surface areas

In order to achieve durable adhesively bonded metal joints, besides choosing a suitable adhesive, in many cases surface pretreatment is essential. This for example, is especially valid for aluminium, aluminium alloys and also for stainless steel. The newly developed, and patented, Ciba laser pretreatment (CLP) uniquely combines processing benefits with the opportunity for cost savings and excellent performance of adhesively bonded metal joints. CLP also stands out with its environmentally friendly way of operation. © 1999 Elsevier Science Ltd. All rights reserved.
