PRESSURE-SENSITIVE ADHESIVE TAPES FOR THE ADHESIVE BONDING OF WINDOWS MORE PARTICULARLY IN MOBILE EQUIPMENT

摘要

Composite made of two substrates for use for optical, electronic and/or precision-engineered equipment, comprising a first substrate and a second substrate and, arranged so as to connect the first substrate to the second substrate, an adhesive layer, wherein the adhesive layer comprises an adhesive which has, relative to the mixture, (a) from 60% by weight to 90% by weight of a first polymer component based on polyacrylate and (b) from 10% by weight to 40% by weight of a second polymer component based on elastomers, where the second polymer component is essentially not miscible with the first polymer component, so that the adhesive is present in at least two separate phases in the adhesive layer.

1. A composite of two substrates for use for optical, electronic and/or precision mechanical devices, comprising a first substrate and a second substrate and an adhesive layer arranged to join the first substrate to the second substrate, wherein the adhesive layer comprises or consists of an adhesive comprising
(a) a first, polyacrylate-based polymer component in an amount of from 60% by weight to 90% by weight of the mixture and (b) a second, elastomer-based polymer component in an amount of from 10% by weight to 40% by weight of the mixture, wherein the second polymer component is substantially not miscible with the first polymer component so that the adhesive is present in the adhesive layer in at least two separate phases.
