Adhesive bonding of porous solid substrates, e.g. paper

摘要

A process for the adhesive bonding of porous solid materials with rapid initial adhesion and the possibility of immediate further processing, using a one-component dispersion adhesive in the form of a stable precoagulate of acrylate copolymers with average mol. wts. of 80,000-300,000, a glass transition point (Tg) of -10 to -30 deg C and a solid content of 40-60% in the aqueous dispersion.
