摘要:
The present invention relates to a pressure sensitive adhesive composition comprising a copolymer comprising pyrrolidonoethyl acrylate or pyrrolidonoethyl methacrylate. This composition may be used as part of a transdermal drug delivery device.
摘要:
The present invention provides pressure-sensitive adhesives having a refractive index of at least 1.50. The pressure-sensitive adhesives comprise at least one monomer containing a substituted or an unsubstituted carbazole group.
摘要:
The object of the present invention is to provide a novel adhesive. The characteristics of the present invention is an adhesive comprising an organic polymer having a main chain formed by a water-soluble polymer unit, and a hydrophilic organic group and a self-assembling group bonded to the water-soluble polymer unit; and a curing agent.
摘要:
The invention relates to a novel poly(ethylene oxide)imine; a novel amine reactive moiety; a novel moisture activated latent curing adhesive or sealant mixture comprising (1) a ketimine or aldimine, and (2) an amine reactive moiety; and a novel moisture activated latent curing adhesive or sealant comprising the reaction product of (1) and (2).
摘要:
A solid adhesive having adhesive resins, benzylidene sorbitol, isothyazoline preservatives, organic solvents, and about 25-60% water, the components being balanced such that the solid adhesive has good formability or shapability. A stick-shaped solid adhesive product made from the solid adhesive has a unique combination of shape-maintainability, bending strength, and crush strength.
摘要:
Polymeric coupling agents incorporate within their structures co-vulcanizable groups such as alkenyl, epoxide, acrylate and/or acrylamide, and metal-complexing groups such as carboxylic, oxime, amine, hydroxamic and/or iminodiacetic groups. The polymeric coupling agents are useful in the adhesion of certain substrates and are particularly useful as adhesives for the adhesion of rubbers with metals. Snytheses of the novel polymeric coupling agents are provided.
摘要:
A repositionable glue stick comprising:a) at least 10 percent by weight of an infusible, non-polar organic liquid dispersible, non-polar organic liquid insoluble, inherently tacky, elastomeric copolymer microsphere, andb) a gelling component in an amount sufficient to provide a Penetration Value of less than 40 mm is disclosed.
摘要:
The invention relates to a device that includes a substrate and a thin film of a photo-switchable adhesive layer applied to at least one surface of the substrate. A method of releasably supporting a product that includes adhering a product onto the thin film of the device and exposing the thin film to light sufficient to cause a change in the adhesive strength of the thin film. A method of making the device is also disclosed.
