Abstract: Adhesive tapes suitable for bonding to clearcoat materials and exhibiting a good shear strength and a bond strength compatible with requirements. Methods apply the adhesive tapes onto clearcoat materials. The adhesive tapes comprise a carrier layer and a layer of pressure-sensitive adhesive, arranged on the outside in the structure of the adhesive tape. The layer of pressure-sensitive adhesive comprises: at least one polymer selected from poly(meth)acrylates and polydiene block copolymers, or at least one blend of at least one poly(meth)acrylate and at least one polydiene block copolymer; and a tackifier resin component comprising at least one terpene phenolic resin, wherein the terpene phenolic resin has a softening temperature as determined by the ring-and-ball method according to ASTM E28, of not more than 140° C.

Abstract: An adhesive that comprises: (a) 35 to 55 wt. % of an elastomer component; (b) 20 to 45 wt. % of an adhesive resin component; and (c) 15 to 40 wt. % of a plasticizing component, wherein (c1) 8 to 35 wt. % of (c) is made of one or more plasticizing oils, and (c2) optionally up to 32 wt. % of (c) is made of one or more plasticizers that differ from plasticizing oils.

Abstract: An adhesive mass consisting of (a) at least one elastomer component, of a polybutadiene-polyvinyl aromatic block copolymer type, having a proportion with respect to the total adhesive mass of 42 to 55 wt. % and having a diblock proportion with respect to the total block copolymer content of 32 to 55 wt. %, (b) at least one adhesive resin, which is a hydrocarbon resin having a DACP value of at least +50° C. and at most +85° c, (c) optionally at least one soft resin having a proportion of 0 to 15 wt. % with respect to the total adhesive mass, and (d) optionally further additives, which adhesive mass is particularly suitable for adhering on rough substrates such as plaster or woodchip wallpaper.

Abstract: The invention relates to a pressure-sensitive adhesive strip containing at least one layer SK1 of a self-adhesive composition based on vinylaromatic block copolymer and containing tackifying resin, wherein the vinylaromatic block copolymer contains at least one polymer block A formed predominantly by polymerization of vinylaromatics, and simultaneously contains at least one polymer block B formed predominantly by polymerization of conjugated dienes, where the proportion of 1,2-bonded conjugated diene in the B block is less than 30% by weight, preferably less than 20% by weight. The invention also relates to a pressure-sensitive adhesive strip of this kind, in which at least layer SK1 has been subjected to irradiation with electrons.

Abstract: An adhesive mass consisting of (a) at least one elastomer component, of a polybutadiene-polyvinyl aromatic block copolymer type, having a proportion with respect to the total adhesive mass of 42 to 55 wt. % and having a deblock proportion with respect to the total block copolymer content of 32 to 55 wt. %, (b) at least one adhesive resin, which is a hydrocarbon resin having a DACP value of at least +50° C. and at most +85° C., (c) optionally at least one soft resin having a proportion of 0 to 15 wt. % with respect to the total adhesive mass, and (d) optionally further additives, which adhesive mass is particularly suitable for adhering on rough substrates such as plaster or woodchip wallpaper.

Abstract: A self-adhesive article comprising (i) at least one carrier material which comprises at least one foamed layer having a first surface A and a second surface B, the at least one foamed layer of the carrier material having a thickness of at least 500 ?m and at most 1800 ?m, a tensile strength in detachment direction of at least 500 kPa, a tensile elongation in detachment direction of at least 300% and a compressive hardness of at least 50 kPa, (ii) a layer HKA of pressure-sensitive adhesive (PSA) assigned to the surface (A), (iii) a PSA layer HKB assigned to the surface (B) and (iv) optionally further layers; the PSA layers HKA and HKB may be two PSA layer combinations.
