摘要:
A low pressure limited overspray handheld aerosol spray gun for spraying a two-component adhesive, a method for spraying a two-component adhesive and a two-component adhesive obtainable by that method. In manufacturing of larger objects, such as matrasses and furniture, adhesives are often applied to fix parts of the large object together. Most adhesives are applied using either air-spray equipment or air-assisted spray equipment.

The invention relates to the utilization of aqueous polymer dispersions or of polymer powders which can be redispersed in water and which are based on protective colloid-stabilized aromatic vinyl-1,3-diene-copolymers in adhesive formulations used in the building industry, whereby the polymer dispersion and the polymer powders are produced by emulsion polymerization of a mixture containing at least one aromatic vinyl and at least one 1,3-diene in the presence of one or more protective colloids, without using an emulsifier, and by optionally drying of the aqueous polymer dispersion obtained thereby.
摘要:
A pressure-sensitive adhesive is prepared by blending (1) a small particle size latex having a hard monomer (such as styrene), a soft monomer (such as butadiene) and, optionally, an acid (such as itaconic acid), and (2) a tackifying resin. These adhesives have an excellent combination of properties including peel adhesion and shear adhesion.

The invention is addressed to an adhesive composition in the form of an aqueous dispersion which, in the form of a thin film, can resist exposure to air over a period of time without losing its adhesiveness and which can be employed under high temperature conditions. The adhesive composition comprises a 20% to 85%, by weight, aqueous dispersion in which the dry solids is formulated of 90% to 10% by weight fine mineral particles and 10% to 90% by weight of a mixture of styrene and butadiene copolymer and a hydrosoluble water retainer.

[Also in Division C3] A pressure-sensitive adhesive tape comprises a backing material, e.g. films of a polyethylene terephthalate, and a tacky adhesive coating composed of an elastomer and a tackifier which is a copolymer of (a) at least one cyclic monoterpene hydrocarbon with optionally an acyclic terpene and (b) styrene, a chlorostyrene or an alkyl- or alkenyl-styrene having less than 13 C atoms. The elastomer may be natural rubber, polyisoprene or a styrenebutadiene rubber and the copolymer may be derived from divinylbenzene, styrene and/or α-methylstyrene and dipentene d-limonene # 3 -carene, α- or #-pinene or turpentine, or a mixture of dipentene, allloo-cimene and terpene oligomers.

摘要:
Fluid activatable adhesive compositions and activating fluid(s) for activating the adhesive composition are described herein. The adhesive compositions contain at least two polymers with different hydrophilicities. The hydrophilic polymer has quick tack when exposed to a hydrophilic solvent, such as water or other aqueous solvent, while the hydrophobic polymer provides strong adhesion to a paper or polymeric substrate. The adhesive composition may contain particulate fillers which enable fast exhaustion of the activation fluid out of the adhesive when applied to a substrate, thereby allowing the hydrophobic polymers of the adhesive composition to achieve strong adhesion of the liner-free label to the paper or polymeric substrate. The particulate fillers may also function as anti-blocking agents when liner-free label media are tightly wound in a roll. The adhesive compositions described herein may be used not only on paper, cardboard, and metal, but also on glass and plastics commonly used in commercial applications.
