Cyanoacrylate-containing compositions that include, in addition to the cyanoacrylate component, an anhydride and a toughening agent comprising a co-polymer of polyvinyl chloride and polyvinyl acetate are provided.

Cyanoacrylate compositions

An apparatus for binding stacks of flat parts comprising a fixing unit for fixing a stack consisting of a plurality of flat parts, a binder application device for applying liquid binder along a narrow face of the stack, and an irradiating unit for curing the binder by irradiating the binder on the narrow face of the stack, a light-emitting diode unit being used for irradiation.

Apparatus for binding stacks of flat parts

A Waterborne adhesive comprising 1 to 50 weight-% of a (meth)acrylate copolymer manufactured by polymerization of at least one ester of methacrylic acid, acrylic acid, crotonic acid and/or itaconic acid with aliphatic alcohols, substituted aliphatic alcohols, aromatic alcohols, polyether glycols, and other copolymerizable monomers, having an acid number from 0 to 150 mgKOH/g, 0 to 40 wt-% of natural polymers 0.5 to 30 wt-% of urea, 0.1 to 20 wt-% of additives, characterized in that the adhesive contains 0.05 to 20 weight-% of a super absorbent polymer.

Waterborne adhesive with improved wet adhesion

The invention provides an adhesive with an aqueous polymer dispersion. The aqueous polymer dispersion comprises a copolymer of a) esters of vinyl alcohol with Cto Cmonocarboxylic acids, b) &#x3b1;,&#x3b2;-unsaturated Cto Ccarboxylic acids or vinyl-substituted phosphonic or sulfonic acids, c) polyunsaturated monomers, and optionally d) non-polar, copolymerizable monomers and e) copolymerizable monomers that carry polar functional groups, where the ratio of c:b ranges from 1:10 to 1:400. The adhesive has high adhesion strength, stable viscosity during high-speed automatic application process and, is optionally, remoistenable with water or becomes water-soluble. The adhesive may be advantageous used as wood adhesive, remoistenable adhesive, label adhesive, bottle adhesive, and the like.

Aqueous dispersion

A filled gum adhesive useful for producing remoistenable layers contains fillers, protective colloids, and a (co)polymer, wherein the (co)polymer is prepared by polymerizing one or more ethylenically unsaturated monomers in the presence of a dispersion of protective colloid and filler particles.
