Abstract:
Holding device that is attachable to a rigid surface comprising in exposed pressure-sensitive adhesive layer wherein the pressure sensitive adhesive is a polymerized precursor wherein the precursor comprises:(a) a monomirl component that contains one or more alkyl acrylates, the alkyl groups of which have an average of 4-14 C atoms, and a minor proportion of at ieast one copolymerizable monomer having a polar group, (b) 5-15 phr of hydrophobic silica, (c) one or more polymerization initiators, and (d) one or more crosslinker compounds in a concentration resulting in a crosslink density using hexanediol diacrylate as a reference crosslinker compound in the concentration of between 0.08-0.13 phr, such that the pressure sensitive is readily removable from the surface and exhibits a compliance of between 5Ã—10âˆ’7 to 2Ã—10âˆ’6 cm2/dyne, and a toughness of between 6Ã—102 to 2Ã—103 pounds/inch2.
