Description

technical field

[0001] This invention relates to adhesive and sealant systems. Background technique

[0002] Adhesive and sealant systems are known from Ullmanns Enzyklopadie dertechnischen Chemie, 4 th Edition, Volume 14, page 227 (1997).

[0003] Adhesive and sealant systems consist of high polymers with the highest possible strength. Most adhesives and sealants contain as building blocks high molecular weight organics or reactive organics that are precursors to polymers and react to form polymers during the bonding and sealing process.

[0004] Various adhesive and sealant systems are known, e.g. based on epoxy, polyurethane or vinyl ester resins, hydrophobic fumed silica compared to hydrophilic fumed silica Is a very effective thixotropic agent. Furthermore, said adhesive and sealant systems can be obtained with better storage stability with hydrophobic fumed silica than with hydrophilic fumed silica (Degussa Schriftenreihe Pigmente (2001) No. ...
