Embodiment

[0093] Examples are described below, which should explain the present invention in detail. It goes without saying that the present invention is not limited to these described examples.

[0094] Preparation of tackifier composition

[0095] According to the amount in Table 1, the 2200B is pre-filled with methyl ethyl ketone. followed by RFE, M580, N3300 or A-Link597 was added sequentially under nitrogen atmosphere with continuous stirring and stirred at 30°C for 1 hour. It was then heated to 40° C. and stirred until the NCO content was constant. Carbon black was then added. The composition is placed in a tightly closable jar with glass spheres, which is closed and mixed by means of a RedDevil-shaker for 1 hour.

Abstract

The present invention relates to an adhesion promoter composition comprising at least one film-forming resin, at least one aromatic polyisocyanate, at least one solvent, and at least one isocyanurate having specific silyl groups. The adhesion promoter compositions according to the invention are particularly suitable for improving the adhesion of adhesives and sealants to glass and glass ceramics.

Description

technical field [0001] The present invention relates to the field of tackifier compositions and their use as precoats for adhesives and sealants. Background technique [0002] Adhesion promoter compositions have long been used to improve the adhesion of adhesives and sealants to various substrates. In this context, especially high demands are placed on adhesion in the automotive industry, so that the use of adhesion promoter compositions in this field has broadly expanded. [0003] For example, US 2008 / 0268261 A1 describes adhesion promoter compositions for glass substrates, which are used in automotive manufacturing, in particular in glazing bonding. Such compositions achieve good adhesion of one- or two-component polyurethane adhesives or sealants on glass substrates. However, such compositions generally have the disadvantage that they have weaknesses with regard to thermal stability and the stability of the adhesive bond in the low temperature range. Furthermore, WO 20...
