Definitions
- the invention relates to adhesive systems consisting of adhesion promoter and adhesive and their use, in particular for the bonding of glass panes in means of transport.
- Bonding is a commonly used joining technology that plays a major role in construction and industry. Modern adhesives are
- reactive coupling agent compositions such as primers or activators
- these are liquid solutions or emulsions that react chemically with the substrates and also with the adhesive, thus forming an interface with the substrate which is optimal for the adhesive.
- mixtures of organic silanes and solvents and optionally organometallic catalysts are often used as adhesion promoters for glass and ceramic surfaces.
- WO-A-2005/059056 describes a primer which comprises, in addition to an organotitanate and an organic solvent, a mercaptosilane and a polyaminosilane and a secondary aminosilane.
- adhesion promoter compositions Another example of such adhesion promoter compositions is taught in WO-A-2009/150064, wherein with a composition containing aromatic aminosilanes, particularly good adhesions to glass and glass-ceramic could be achieved.
- Adhesive compositions no longer meet the speed requirements.
- Very fast curing adhesives require very fast reacting adhesion promoter so that a good adhesion to the substrate can be ensured by reaction with each other.
- the adhesive and the primer are therefore considered to be one
