Hot melt adhesives for glass containers by the sol-gel process

Abstract

Based on organically modified silicates prepared by the sol-gel process, a sealing medium for glass surfaces was developed which overcomes basic difficulties of a hot sealing process performed with conventional thermoplastic organic polymers. The new polymers form a moisture resistant bond to the glass surface and the sealing strength is not affected by water layers usually present on those surfaces. The mechanical and thermal properties can be tailored by composition of the multicomponent system and by reaction conditions. A technical procedure based on the new material can be performed.
