Adhesion Promotion to Green Ceramic Sheets

The application of polyvinyl butyral resin coating on MYLAR* film allows it to form a peelable bond to green ceramic sheet surfaces.

The resin is first dissolved in a suitable solvent or solvent mixture, such as isopropyl alcohol and N-methyl pyrollidone or methanol (0.6 to 1.2% solution). The MYLAR is then coated with the resin solution using any of the standard coating methods, for example, brush, roller coating, etc. The solvents are removed by drying at 70 degrees C for 5 minutes. The coated MYLAR is then bonded to the green sheet at 90 degrees-115 degrees and 60-10 si. The peel strength can be controlled by changing the laminating pressure and temperature and the thickness of the coating. * Trademark of E. I. du Pont de Nemours & Co.
