摘要:
A release agent composition may include a polyester resin (A) and an acrylic polymer (B) in which the acrylic polymer (B) may include a structural unit represented by any structural formula disclosed herein, and a ratio of a blending amount of the polyester resin (A) to a blending amount of the acrylic polymer (B) may be in the range of (A):(B)=50:50 to 95:5 in a mass ratio. The release agent composition may be used to form a release sheet for a single-sided pressure-sensitive adhesive sheet or release sheets for a double-sided (faced) pressure-sensitive adhesive sheet. Further, when the release sheet is wound up in a rolled form, it is possible to suppress the release agent composition from transferring to a surface of the base material of the release sheet and to impart an easy peeling property to the release sheet.

A system and a method for making a web having a complex topography. A substrate having coatable material is contacted by a face-side roller having grooves set into the major surface thereof, the coatable material is then split between the face side roller and the substrate, resulting in a textured surface having a first area associated with the splitting from the major surface, and a second area resulting from splitting associated with areas of the face-side roller having grooves. Raised ridge features produced from the splitting step interconnect portions within the first area, and portions within the second area, and in between the first and second area.

It is an object of the present invention to provide a release material and a release agent, which can be produced by directly coating onto a substrate without requiring the application of an undercoating material even when using a permeable substrate such as paper, which have excellent releasability even when the amount of silicone used is small, have a low change in peel strength over time, have a high residual adhesion ratio of an adhesive tape, seal and the like after release from a release material, and have writability or printability to a release surface.A release material and a release agent are provided, wherein the release layer contains a neutralized resin obtained from a neutralization reaction of an emulsion copolymer of a monomer composition containing from 5 to 80 mass % of an unsaturated carboxylic acid monomer with a basic substance, and a silicone emulsion and/or a silicone dispersion.

An adhesive tape with an antistatic release coating is provided. The release includes an antistatic additive made from a reaction product of from about 1 to 30 parts hydrophilic monomer, from about 5 to 40 parts ionic monomer, and from about 20 to 80 parts hydrophobic monomer. A release agent can also be added to the release coating. The adhesive tape does not recoil upon itself when unrolled from the tape core.

A dry erase sheet is disclosed including a flexible substrate having a dry erase top surface and an opposing bottom surface. An adhesive is disposed on at least a portion of the bottom surface. A polymeric release layer is disposed on at least a portion of the dry erase top surface. A dry erase pad including a plurality of dry erase sheets and method of making dry erase sheets are also disclosed.
摘要:
The invention concerns a silicone/adhesive complex comprising at least a silicone coating applied on a first support and an adhesive coating applied on a second support and whereof the release force of a silicone/adhesive interface is capable of being modulated. The invention is characterised in that its silicone coating is derived from polymerisation and/or crosslinking of polyorganosiloxane monomers, oligomers and/or polymers and said silicone coating further comprises at least an additive regulating the release force of a silicone/adhesive interface and whereof the activity is initiated and capable of being modulated by electron beam irradiation.

Ink-imprintable release coating compositions are described which comprise a polymer comprising a polyurethane, a fluoroacrylate polymer or copolymer, or an addition cured or a condensation cured silicone polymer containing dispersed and/or emulsified resin particles, resin particle domains, or both, and, optionally, inorganic particles. The resin particles comprise resins which are different from the polymers and the resins comprise polyurethanes, polyamides, and polyureas. Ink-imprintable label, tape and stamp constructions also are described which comprise a plurality of contiguous labels, tapes or stamps in a roll or stacked sheet configuration without an independent release liner wherein the labels, tapes and stamps have a pressure-sensitive adhesive on the back surface and a cured ink-imprintable release coating on the face surface.
摘要:
Adhesive tapes (e.g., duct tapes) having a backing comprising a compatibilized release composition are reported. The compatibilized release composition comprises a thermoplastic olefin-based polymer comprising an acid or a base functionality and a polymeric release material comprising an acid or a base functionality. The functionality of the thermoplastic olefin-based polymer and the functionality of the polymeric release material provide an acid-base interaction that compatibilizes the release composition.
