Adhesives for use on user-to-mask interfaces of a respiratory mask and methods of preparing the same are provided. The adhesive includes greater than or equal to about 1 wt. % to less than or equal to about 15 wt. % of one or more glycerides; greater than or equal to about 0.50 wt. % to less than or equal to about 5 wt. % of one or more polyacrylates; greater than or equal to about 1 wt. % to less than or equal to about 10 wt. % of one or more polyethers; greater than or equal to about 25 wt. % to less than or equal to about 45 wt. % of one or more N-vinylpyrrolidone polymers; and a balance of water. The method includes forming a first aqueous mixture, forming a second aqueous mixture, and admixing the first aqueous mixture and the second aqueous mixture to form a substantially homogeneous mixture that defines the adhesive.

An optical adhesive sheet having a lamination structure includes a first adhesive layer, a second adhesive layer, and a substrate located between the first and the second adhesive layers. The first adhesive layer has a thickness of 30 μm or more and a storage modulus of 1.0×104 Pa or more at 95° C. The second adhesive layer has a loss tangent of 0.08 or more at 95° C. A polarizing film having a lamination structure including a polarizing film and the optical adhesive sheet. A liquid crystal display device having a multilayer structure including a resin-made covering member, a liquid crystal panel, and the optical adhesive sheet. In the liquid crystal display device, the optical adhesive sheet is attached to the resin-made covering member on the side of the first adhesive layer and attached to the polarizing film of the liquid crystal panel on the side of the second adhesive layer.
摘要:
Provided is a transparent pressure-sensitive adhesive agent convertible into an adhesive agent that allows adherends to be instantly fixed to each other, allows the adherends to be reattached to each other, is excellent in processability such as being able to be cut into a sheet shape, is not peeled from the adherends even when exposed to a high-temperature atmosphere such as one in a fire, and has such transparency as to hardly impair the designs of the adherends. The transparent pressure-sensitive adhesive agent convertible into an adhesive agent has pressure-sensitive adhesive property before being sintered, and has adhesive property after being sintered.
摘要:
A water-soluble pressure sensitive adhesive comprises a homogeneous blend comprising (a) a polymer selected from the group consisting of N-vinyl caprolactam homopolymers, N-vinyl pyrrolidone copolymers, and mixtures thereof and (b) a non-volatile plasticizer comprising a monohydric or polyhydric alcohol having hydrophilic-lipophilic balance of about 2 to about 10. The N-vinyl pyrrolidone copolymers comprise about 60% or less by weight N-vinyl pyrrolidone.

The present invention relates to a medical device having a wetted hydrophilic coating comprising: a coating composition containing a hydrophilic polymer and a wetting agent comprising water and one or more lubricant(s).
摘要:
The present invention aims at provision of a patch with suppressed occurrence of adhesive residue on the skin after peeling in the presence of water due to perspiration and the like.The patch has an adhesive layer provided on at least one surface of a support, and the adhesive layer is formed by blending the following component (A)-component (C): (A) a copolymer obtained by copolymerization of a monomer containing a carboxyl group, (meth)acrylic acid ester and vinylpyrrolidone as essential components; (B) a copolymer obtained by copolymerization of a monomer having a basic group and (meth)acrylic acid ester as essential components; and (C) a liquid component, and crosslinking the blend.
摘要:
An adhesive composition is described which has improved initial tack, long-term adhesion, water uptake and translucency characteristics and may be prepared by melt extrusion. Uses of these compositions are also described, for example, their use as blister pads and wound dressings.

A pressure sensitive adhesive comprising a mixture of: a radiation-crosslinkable polymer A) composed of at least 40% by weight of C1 to C18 alkyl (meth)acrylates, and a polymer B) composed of at least 20% by weight of vinylpyrrolidone and of less than 40% by weight of C1 to C18 alkyl (meth)acrylates, wherein the fraction of the polymer B) in the mixture is less than 15% by weight, based on the sum of A)+B).
摘要:
Disclosed herein is an elastomeric joint tape used in the fabrication of panelized wall systems with elastomeric joints that are resistant to cracking. The joint tape is made from an elastomeric backing material with an adhesive applied to a face, and optionally, a release liner laminated to the adhesive. In use, building panels are fastened to a frame with the edges adjacent to each other. The joint tape is applied to the seam between the panels and the wall is then finished with an elastomeric finish. Also disclosed is a method of manufacturing the elastomeric joint tape.
