Abstract:
The invention relates to a method and suitable adhesive material compositions for adhering a substrate on cold and moist surfaces, wherein the surface temperature is lower than the dew point temperature of the air which is in contact with the surface, and wherein the adhesive material composition contains an adhesive material polymer which is formed from specific quantities of 2-ethylhexylacrylate, monomers selected from C1 to C2 alkyl(meth)acrylates, styrene, acid monomers and optionally further monomers in the presence of molecular weight regulators.
Abstract:
The present invention relates to a formulation comprising: i) an aqueous polymer dispersion comprising: a) at least one homo- or copolymer P containing in the form of polymerized units at least one ethylenically unsaturated monomer; b) at least 6% by weight, based on the total of the ethylenically unsaturated monomer, of at least one saccharide-compound S; wherein in a) the at least one homo- or copolymer P is obtained by polymerization of the at least one ethylenically unsaturated monomer in the presence of at least a part of the at least one saccharide-compound S from b); ii) at least one tackifier.
Abstract:
The invention relates to a protective adhesive film made of a polymer film which is coated with a crosslinked adhesive composition. The adhesive composition contains an adhesive polymer which is made by means of an emulsion polymerization in the presence of starches made of soft monomers, which when polymerized as homopolymers have a glass-transition temperature of less than 0 °C, ethylenically unsaturated acids or acid anhydrides, and optionally additional monomers that differ from (i) and (ii). The adhesive composition contains specific crosslinking agents, wherein the crosslinking reaction caused by the crosslinking agents ends before the protective adhesive film is adhered onto a substrate.
