Abstract
Official abstract text for this publication.
The intention is to provide powerful pressure sensitive adhesives with high adhesion and adjustable cohesive failure characteristics. This is accomplished with pressure sensitive adhesives which comprise 30-90 wt % of at least one poly(meth)acrylate; 10-60 wt % of three-dimensional bodies K made from an inorganic material with a maximum extent of 40 to 300 μm; and 0.1-10 wt % of at least partly expanded microballoons M, based in each case on the total weight of the pressure sensitive adhesive. Another subject of the invention is an adhesive tape which comprises a pressure sensitive adhesive of this kind.
First claim
Opening claim text (preview).
1 . A pressure sensitive adhesive comprising 30-90 wt % of at least one poly(meth)acrylate; 10-60 wt % of three-dimensional bodies K made from an inorganic material with a maximum extent of 40 to 300 μm; and 0.1-10 wt % of at least partly expanded microballoons M, based in each case on the total weight of the pressure sensitive adhesive. 2 . The pressure sensitive adhesive according to claim 1 , wherein the inorganic material of the three-dimensional bodies K is glass, ceramic and/or flyash. 3 . The pressure sensitive adhesive according to claim 1 , wherein the three-dimensional bodies K are solid glass beads, hollow ceramic beads and/or hollow flyash beads. 4 . The pressure sensitive adhesive according to claim 1 , wherein the maximum extent of the three-dimensional bodies K is 45 μm to 150 μm. 5 . The pressure sensitive adhesive according to claim 1 , wherein the pressure sensitive adhesive contains 30-50 wt % of three-dimensional bodies K. 6 . The pressure sensitive adhesive according to claim 1 , wherein the pressure sensitive adhesive contains 30-50 wt % of three-dimensional bodies K having a maximum extent of 45 to 150 μm. 7 . The pressure sensitive adhesive according to claim 1 , wherein the weight ratio of three-dimensional bodies K to at least partly expanded microballoons M is from 6:1 to 30:1. 8 . An adhesive tape comprising a pressure sensitive adhesive A, which pressure sensitive adhesive A is a pressure sensitive adhesive according to claim 1 . 9 . The adhesive tape according to claim 8 , wherein the adhesive tape comprises on at least one side of the pressure sensitive adhesive A a further pressure sensitive adhesive. 10 . The pressure sensitive adhesive according to claim 2 , wherein the maximum extent of the three-dimensional bodies K is 45 μm to 150 μm. 11 . The pressure sensitive adhesive according to claim 3 , wherein the maximum extent of the three-dimensional bodies K is 45 μm to 150 μm. 12 . The pressure sensitive adhesive according to claim 2 , wherein the pressure sensitive adhesive contains 30-50 wt % of three-dimensional bodies K. 13 . The pressure sensitive adhesive according to claim 3 , wherein the pressure sensitive adhesive contains 30-50 wt % of three-dimensional bodies K. 14 . The pressure sensitive adhesive according to claim 2 , wherein the pressure sensitive adhesive contains 30-50 wt % of three-dimensional bodies K having a maximum extent of 45 to 150 μm. 15 . The pressure sensitive adhesive according to claim 3 , wherein the pressure sensitive adhesive contains 30-50 wt % of three-dimensional bodies K having a maximum extent of 45 to 150 μm. 16 . The pressure sensitive adhesive according to claim 2 , wherein the weight ratio of three-dimensional bodies K to at least partly expanded microballoons M is from 6:1 to 30:1. 17 . The pressure sensitive adhesive according to claim 3 , wherein the weight ratio of three-dimensional bodies K to at least partly expanded microballoons M is from 6:1 to 30:1. 18 . An adhesive tape comprising a pressure sensitive adhesive A, which pressure sensitive adhesive A is a pressure sensitive adhesive according to claim 2 . 19 . An adhesive tape comprising a pressure sensitive adhesive A, which pressure sensitive adhesive A is a pressure sensitive adhesive according to claim 3 .
