摘要:
A method is disclosed. The method comprises combining at least a polymer adhesive material, a thickener, and water to form adhesive compositions having a pH of 4 to 10, and identifying the adhesive compositions having a stringing length of 9 cm or less and one or more of the following properties: a set time of 180 seconds or less, a phase lag of 45 degrees or less, a viscosity of 3,000 to 50,000 cP, a complex shear modulus of 50 to 1000 Pa, and a sag distance of 10 mm or less.

An adhesive composition includes a polymer adhesive material and a thickener. The adhesive composition has a stringing length of 9 cm or less and a phase lag of 45 degrees or less or a sag distance of 5 mm or less. The adhesive can be formed by combining a vinyl acetate polymer, an alkali swellable thickener, an alkali material, and water.

An adhesive composition includes 5 to 40% wt polyvinylpyrrolidone; 3 to 20% wt alkanoate blend including a first Cn carboxylic acid salt and a second Cm carboxylic acid salt, where n and m are integers in a range from 12 to 22; 20 to 60% wt of a water-soluble or water-dispersable solid material; 0.5 to 30 wt % of a liquid polyhydric alcohol; and 15 to 60% wt water. The adhesive composition can be clear and in glue stick form.

A cyanoacrylate-based adhesive composition is disclosed. The cyanoacrylate-based adhesive composition includes a cyanoacrylate monomer, and a bleachable dye including a Michler's hydrol cation or derivatized Michler's hydrol cation, paired with a non-nucleophilic anion that provides a stable color to the cyanoacrylate-based adhesive.

摘要:
The invention is a mating film. The mating film comprises a base sheet having a first major surface. A plurality of generally parallel ridges project from the first major surface. The ridges comprise a stem portion attached to the base sheet and generally upright from the base sheet. A head portion of each ridge is spaced from the first major surface and extends generally laterally from the stem portion so as to define a lateral distance. The center of each stem portion of each ridge is spaced from the center of each adjacent ridge stem portion by a distance greater than about 2 times lateral distance defined by the head portion.

Disclosed is a release material applied to a sheet material that provides for temporary repositioning of an adhesive over the release material. Over time the adhesion between the release material and the applied adhesive builds such that the adhesive cannot be removed from the release material without damaging the underlying sheet material. The release material includes an free nitrogen containing basic group. The release material is dispersed on a flexible substrate and the release material allows for repositioning when contacted with a pressure sensitive adhesive, which includes a free carboxylic acid group, for at least 1 minute and not more than 10 minutes.
