Abstract: The aim is to reduce the flagging tendency of an adhesive bond using a UV-crosslinkable adhesive. This aim is accomplished by provision of a composition which comprises at least one UV-crosslinkable polyacrylate and at least one terpene-phenolic resin, the total concentration of the terpene-phenolic resins being 1 to 5 wt %, based on the total weight of the composition. The invention additionally relates to a pressure-sensitive adhesive produced on the basis of this composition, an adhesive tape based on said adhesive and the use of said tape for wrapping elongate material such as cable harnesses, for example.

Abstract: A pressure-sensitive adhesive for bonding to various surfaces, such as metals, plastics, and also vehicle finishes, with rapid wetting and high adhesion, with good shear strengths and bond strengths under different conditions and without undergoing dewetting even under lasting mechanical load, comprises: a) at least 50 wt % of at least one polymer A whose monomer basis comprises the following monomers: a1) at least one (meth)acrylic ester having a homopolymer glass transition temperature of not more than −60° C. and an alcohol component based on a branched, primary alcohol, having an iso index of 1; a2) at least one (meth)acrylic ester having an alcohol component based on a linear C1-C18 alcohol; a3) acrylic acid; b) at least 5 wt % of at least one synthetic rubber; and c) at least 10 wt % of at least one peel adhesion-reinforcing resin. Also disclosed is an adhesive tape comprising a foamed carrier and the pressure-sensitive adhesive.

Abstract: A powerful pressure-sensitive adhesive which is notable by way of good wetting and dewetting behaviour on surfaces having different surface energies comprises at least 50 wt %, based on the total weight of the pressure-sensitive adhesive, of at least one polymer A which may be derived from the following monomer composition: a1) 55 to 75 wt % of at least one (meth)acrylic ester having a homopolymer glass transition temperature of not more than −60° C. and an alcohol component based on a branched, primary alcohol, having an iso index of 1; a2) 20 to 40 wt % of at least one (meth)acrylic ester having an alcohol component based on a linear C1-C18 alcohol; a3) 5 to 15 wt % of acrylic acid. The pressure-sensitive adhesive of the invention reveals particularly good properties when combined with a foamed carrier.
