A curable composition comprising: a hydroxy-functional or ether-functional (meth)acrylate copolymer, an epoxy resin; water; a photocatalyst, and optionally a polyvinyl acetal polymer and/or a film-forming polymer. When cured, provides structural bonding adhesives that are curable under high humidity conditions.

Acrylic-epoxy adhesive composition

The present disclosure provides a photopolymerizable composition. The photopolymerizable composition includes at least one urethane component, at least one monofunctional reactive diluent, an initiator, and optionally an inhibitor. The present disclosure also provides an article including the reaction product of the photopolymerizable composition. Further, the present disclosure provides a method of making an article. The method includes (i) providing a photopolymerizable composition and (ii) selectively curing the photopolymerizable composition to form an article. The method optionally also includes (iii) curing unpolymerized urethane component and/or reactive diluent remaining after step (ii). Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying an article; and generating, with the manufacturing device by an additive manufacturing process, the article based on the digital object. A system is also provided, including a display that displays a 3D model of an article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of an article.

Photopolymerizable compositions including a urethane component and a monofunctional reactive diluent, articles, and methods

Articles that include at least one application layer; at least one bead bond layer (); a layer of optical elements () that are partially embedded in the at least one bead bond layer (); and at least one reflective layer () that is located functionally between the layer of optical elements () and the bead bond layer (), wherein the at least one bead bond layer (), the at least one application layer, or both comprise a cured product of an adhesive compositions that include polymerized units of one or more (meth)acrylate ester monomers derived from an alcohol containing 1 to 14 carbon atoms; at least one of urethane acrylate polymer or at least one acrylic copolymer; and at least one initiator.

Articles having adhesive layers including urethane acrylate polymer or acrylate copolymer

A film is described comprising a (meth)acrylic polymer and a polyvinyl acetal (e.g. butyral) resin. In some embodiments, the film has a glass transition temperature (i.e. Tg) ranging from 30&#xb0; C. to 60&#xb0; C. In some embodiments, the film has a gel content of at least 20% or greater. In some embodiments, the film has an elongation at break of at least 175%. The film typically comprises photoinitiator as a result of the method by which the film was made. The film may be a monolithic film or a layer of a multilayer film.

Acrylic polyvinyl acetal films and composition

A light directing article comprises an acrylic polyvinyl acetal film to protect the optical elements of the light directing article. The acrylic polyvinyl acetal film has a Tg of at least 30&#xb0; C. and comprises a (meth)acrylic polymer and polyvinyl acetal polymer. The acrylic polyvinyl acetal film is flexible and durable to mechanical deformation.

Sample partitioning devices and methods of making and using the same are described. A sample partitioning device includes a first film having an array of discrete stems each extending from a first major surface thereof, and a second film having an array of discrete wells formed into a second major surface thereof. The stems of the first film and the wells of the second film are mated with each other. The mated stems and wells are separable from each other, and during the removal of the stems from the wells, one or more voids are created inside the wells to suction an aqueous test sample into the wells.

Stem-well films for sample partitioning

A film is described comprising a (meth)acrylic polymer and polyvinyl acetal polymer composition, wherein the film comprises a structured layer.

Acrylic films comprising a structured layer

A film is described comprising a first film layer having a Tg ranging from 30&#xb0; C. to 60&#xb0; C. The first film layer comprises a (meth)acrylic polymer and polyvinyl acetal polymer composition. The film further comprises a second layer proximate the first film layer. The second layer is different than the first film layer. The second may be a cured (meth)acrylic polymer film or coating; a backing such as thermoplastic polymer, woven or nonwoven fabrics, metal foils, paper, foams; or a coverfilm such as a fluoropolymer.

Acrylic polyvinyl acetal films comprising a second layer

An adhesive article is described comprising a foamed adhesive layer and a non-foamed adhesive layer. The adhesive of each adhesive layer comprises a tetrahydrofurfuryl (meth)acrylate copolymer; an epoxy resin; a polyether polyol; and optionally a hydroxy-functional film-forming polymer. The adhesive may be used in structural and semi-structural bonding applications and is designed to fail cohesively.

Multilayer adhesive article

A film is described comprises a (meth)acrylic polymer and a polyvinyl acetal (e.g. butyral) resin. The film has a tensile elastic modulus of at least 1 MPa at 25&#xb0; C. and 1 hertz and a glass transition temperature (i.e. Tg) less than 30 C. The film typically comprises photoinitiator as a result of the method by which the film was made. In one embodiment, the film is heat bondable and further comprising a backing.
