Abstract: A slip control article including a backing layer having a first surface with an array of at least 100 upstanding stems per square inch and a second surface. At least a portion of the upstanding stems is an elastomeric material and the stems have an aspect ratio of at least 1.25. The first surface has a static coefficient of friction when dry of at least 0.6 and a static coefficient of friction when wet within 20% of the static coefficient of friction when dry. The first surface has a peel strength and a tensile strength of substantially zero when engaged with another slip control article. The first surface has a relatively high shear strength when engaged with another slip control article. The high shear forces are due primarily to the frictional properties of the elastomeric materials, not a mechanical interlock of the stems, such as on a mechanical fastener.

Abstract: A diffusional gas transfer system and method having a membrane disposed between a first gas domain and a second gas domain. The first gas domain includes a first mechanism for directing a first environmental gas flow transversely over and in contact with a first surface of the membrane. The second gas domain includes a second mechanism for directing a second environmental gas flow transversely over and in contact with a second surface of the membrane. The membrane is a diffusional gas transfer medium having a multiplicity of tortuous pathways extending from the first surface of the membrane to the second surface of the membrane. The void volume fraction of the membrane is at least 0.2. The membrane is capable of substantially blocking the transfer of particles from the first gas domain to the second gas domain, while permitting the diffusion of gases between the first and second gas domains.

Abstract: A security label with a sheet material having a first major surface. An adhesive layer containing an identifier medium is coated on the first major surface. A barrier medium is selectively applied on an exposed surface of the adhesive layer for at least partially blocking diffusion of the identifier medium from the adhesive layer into a substrate. A release liner may be provided that extends substantially over the exposed surface of the adhesive layer. A method of preparing the security label includes applying a barrier medium in the form of an identifier pattern to a low energy surface material. The low energy surface material is laminated to a security label having an adhesive layer containing an identifier medium. When the low energy surface material is removed from the adhesive layer, the barrier medium substantially transfers to the adhesive layer to block diffusion of the identifier medium into a substrate.
