Systems and methods for customizing medical tapes from a roll stock at customer use sites are provided. The system includes a tape converting machine where an adhesion modification mechanism is configured to modify adhesion properties of the tape from the roll stock, automatically or based on received customization instructions.

On-demand manufacturing for medical tapes

The disclosed patterned wavelength-selective material and process for making the patterned wavelength-selective material uses patterned applied adhesive and a structurally weak wavelength-selective material that includes portions that contact the adhesive and break to remain in contact with the adhesive. In one embodiment, the wavelength-selective material comprises an array of sections with cuts at least partially through a wavelength-selective film at each section secured to the adhesive. In another embodiment, the wavelength-selective film comprises a transfer stack of layers.

Patterned wavelength-selective film

Wavelength-selective films are visibly apparent under the selective wavelength. Wavelength-selective films typically reflect off axis the selected wavelength and therefore can provide high-contrast against a background when applied in a pattern on a substrate. However, it is difficult to apply unique patterned embedded images from film. Disclosed is a cost-effective method and construction of a patterned wavelength-selective image to a substrate. In the disclosed wavelength-selective image, wavelength-selective film particles are applied to an adhesive pattern to create the wavelength-selective image.

Pressure-sensitive adhesive compositions are described comprising polymerized units of (meth)acrylate monomer. Also described are articles comprising such pressure-sensitive adhesive composition.

Adhesives comprising polymerized units of secondary hexyl (meth)acrylates

Controlled radical initiators, reaction mixtures containing the controlled radical initiators and various ethylenically unsaturated monomers, polymeric materials formed from the reaction mixtures, crosslinkable compositions containing the polymeric materials, crosslinked compositions formed from the crosslinkable compositions, and articles containing the polymeric materials, the crosslinkable compositions, or the crosslinked compositions are provided. The controlled radical initiators are bis-dithiocarbamate or bis-dithiocarbonate compounds having a single carbon between the two dithiocarbamate or dithiocarbonate groups. Also attached to that single carbon is a ketone group.

Polymeric materials formed using initiators with two thiocarbonylthio-containing groups

Controlled radical initiators, reaction mixtures containing the controlled radical initiators and various ethylenically unsaturated monomers, polymeric materials formed from the reaction mixtures, crosslinkable compositions containing the polymeric materials, crosslinked compositions formed from the crosslinkable compositions, and various articles are provided. The controlled radical initiators are bis-dithiocarbamate or bis-dithiocarbonate compounds having a carbonyl group between the two dithiocarbamate or dithiocarbonate groups.

Polymeric materials formed using initiators with a ketone group and two thiocarbonylthio-containing groups

Controlled radical initiators that are ketone-containing dithiocarbamate or ketone-containing dithiocarbonate compounds are used to form polymeric materials that have a single polymeric block or multiple polymeric blocks. Reaction mixtures containing controlled radical initiators and various ethylenically unsaturated monomers, polymeric materials formed from the reaction mixtures, crosslinkable compositions containing the polymeric materials, crosslinked compositions formed from the crosslinkable compositions, and articles containing the polymeric materials, the crosslinkable compositions, or the crosslinked compositions are provided.

Ketone-containing controlled radical initiators for polymerization reactions

Crosslinkable polymeric materials, crosslinked polymeric materials, articles containing the crosslinkable polymeric materials or crosslinked polymeric materials, and methods of making the articles and various compositions are provided. More particularly, the crosslinkable composition contains a) a first polymeric material, which has terminal dithiocarbamate or dithiocarbonate groups, b) a crosslinking composition containing a chlorinated triazine crosslinking agent and/or a crosslinking monomer having two or more ethylenically unsaturated groups, and c) a thixotropic agent containing metal oxide particles. The crosslinkable composition may be printable or dispensed. In some embodiments, the crosslinked composition is a pressure-sensitive adhesive.
