POLAR ADHESIVE RESINS FOR LOW-ENERGY SURFACES

摘要

For adhesive bonding to low-energy substrates, the use of an adhesive resin having a softening point of up to 115°C as an adhesive resin for polyacrylate pressure-sensitive adhesives is specified, the adhesive resin having a molar mass distribution that is characterised in that the integral of the curve of the molar mass distribution up to a molar mass of 350 g/mol makes up at least 15% of the total area under the curve of the molar mass distribution. The integral of the curve of the molar mass distribution up to a molar mass of 350 g/mol preferably makes up at most 20% of the total area under the curve of the molar mass distribution.
