Provided are adhesive articles that include a barrier layer that is substantially impermeable to oxygen gas at ambient temperature and pressure along with a heat-bondable layer, which could be a discrete layer adjacent to the barrier layer or integral with the barrier layer. The adhesive article further includes a backing extending across and coupled to the barrier layer and an adhesive layer extending across and coupled to the backing opposite the barrier layer. The barrier layer reduces or eliminates migration of plasticizers from the bonded seal into the adhesive article, limiting deterioration of tape performance over time.

Adhesive article with a barrier layer

Siliconized fibrous webs are described. The siliconized webs include a fibrous web saturated with an electron beam cured silicone composition. Siliconized webs with electron beam cured silicone coating are also described. Methods of preparing both the coated and uncoated siliconized fibrous webs are also described.

Electron beam cured siliconized fibrous webs

A double-sided adhesive tape assembly that includes a double-sided tape having a pressure sensitive adhesive ('PSA') on each side thereof and a delaminatable release liner in contact with the pressure sensitive adhesive ('PSA') on one or both sides of the double-sided tape is disclosed. A roll of the double-sided adhesive tape assembly is also disclosed. Methods of making and using the double-sided adhesive tape assembly are also disclosed.

Release liner for pressure sensitive adhesives and method of use

Pressure sensitive adhesive compositions containing 92 to 99.9 parts of a block copolymer adhesive composition and 0.1 to less than 8 parts of an acrylic adhesive composition are described. Tapes including such adhesives, and methods of making such tapes are also described.

Blends of block copolymer and acrylic adhesives

Pressure sensitive adhesives comprising a linear block copolymer having a rubbery block and at least one glassy block; a multi-arm block copolymer having at least three arms, each having both a rubbery block and a glassy block; a first high glass transition temperature tackifier compatible with the rubbery blocks; a second high glass transition temperature tackifier having compatible with the glassy blocks; and at least one of a low Tg tackifier, a plasticizer, and combinations thereof, are disclosed. Tapes that include such adhesive, methods of making such tapes, and bonded composites using such adhesives and tapes are also disclosed.

Block copolymer blend adhesives with multiple tackifiers

Methods of electron beam curing nonfunctional polysiloxanes and silanol terminated polysiloxanes are described. The resulting release materials are also described.

Electron beam cured silicone release materials

Methods of electron beam curing nonfunctional polysiloxanes blended with functional polysiloxanes are provided. The resulting release materials are also provided.

A process to mark a multilayered article with a laser (). The multilayered article () includes a laser-markable layer () having at least one organic polymer and at least one light-sensitive pigment therein, and including at least one release agent associated with the laser-markable layer. Laser-marking of the laser-markable layer is accomplished by directing laser radiation () into the multilayered article through the release agent () to induce an interaction between the light-sensitive pigment and the organic polymer. As a result of the interaction, a visually perceptible marking () is formed in the article. The laser-marked article includes a laser-markable layer and a first release agent associated with a surface of the laser-markable layer. The marking(s) in the laser-markable layer is visible through the layer of release agent, and the marking is a result of the laser-induced interaction between the light-sensitive pigment and the organic polymer.

Laser marking process and articles

Polymer foams, including acrylic foams, comprising low amounts of high-surface-area silica are described. Methods of preparing such foams and articles comprising such foams are also described.

Polymer foams

A release liner providing more roll stability (i.e., the coils forming the roll are less likely to fall apart when the roll is held suspended along its outer circumferential edge) when used with double-sided tape having a heat activated adhesive (&ldquo;HAA&rdquo;) side and a pressure sensitive adhesive (&ldquo;PSA&rdquo;) side. The release liner includes a front liner side comprising a release layer in contact with, bonded to and readily removable from the PSA side and a back liner side comprising a roll stability layer. The roll stability layer comprises an ethylene vinyl acetate and contacts the HAA side when the adhesive tape assembly is formed into a roll.
