A simple, highly versatile method for fixing smooth materials that utilizes a water pasting method can be provided by interposing an ionic liquid between smooth materials such as glass or resin not impregnated with an ionic liquid and fixing these smooth materials.

The present disclosure is generally directed to solvent mixtures for swelling and bonding polymeric substances for use in facilitating the connection of polymeric substances to other parts. A swelling solvent solution according to the present disclosure may comprise between 5% and 95% by volume n-Octane and between 5% and 95% by volume of either a heptane isomer (such as n-Heptane) or a nonane isomer (such as n-Nonane). The swelling solvent solution may be used to swell polymeric parts to enable the parts to be attached to other parts. A bonding solvent solution according to the present disclosure may comprise between 2% and 98% by volume of at least one of: acetone, MEK, heptane, octane, nonane, isohexane, and THF, and between 2% and 98% by volume cyclohexanone. The bonding solvent solution may be used to bond polymeric parts to other parts.

The present disclosure provides methods of improving adhesion of a non-di-(2-ethylhexyl)phthalate (DEHP) plasticized polyvinyl chloride (PVC) to an acrylic-based polymer or an ABS-based polymer. Such methods may comprise blending the acrylic-based polymer or ABS-based polymer with an impact modifier so that a rubber content in the acrylic-based polymer or ABS-based polymer is greater than 12% (w/w). Also provided are components of a device (e.g., a medical device) made by the disclosed methods.

Disclosed herein are sealing solutions for sealing water-soluble films, in particular aqueous mixtures including one or more polymeric solvents such as polyols. Aqueous sealing solutions including a relatively dilute solvent for one or more polymeric components of the water-soluble film (e.g., water-soluble polymeric components thereof, such as polyvinyl alcohol (PVOH)) can exhibit one or more benefits, including a reduction in dissolution of the film by the sealing solution and an increase in seal strength. Also disclosed are sealed articles formed with the sealing solutions, for example water-soluble packets containing various liquid or solid compositions.

Methods for bonding polymeric substrates to component parts, and medical devices assemblies including a tubing and a component part bonded together using a solvent containing a tackifier.

Provided are primer formulations for solvent cement bonding comprising cyclopentanone and, optionally, at least one additional organic solvent. The primer formulations are effective for solvent cement bonding plastic components together, wherein the plastic components may include ABS, PVC, or CPVC pipes and/or fittings.

A coated rubber composition includes a rubber composition coated with a liquid refresh agent selected from the group consisting of one or more liquid terpenes, limonene, carvone, pinene, pine needle oil, citral, orange oil, C.sub.9-C.sub.15 aliphatics, C.sub.9-C.sub.15 cycloaliphatics, ethyl lactate, dipentene, 1,8-cineole, eucalyptol, citronellol, geraniol, citronellene, terpinen-4-ol, and combinations thereof. A method of application and a coated rubber composition are also disclosed.

Provided are a heat-shrinkable label and a package each having solvent bonded-portion where solvent penetration-through is not caused even when the film is thin. Provided are particularly a heat-shrinkable label and a package each having solvent bonded-portion gaining a high peel strength stability even when the film is passed through a tubing step made high in speed. A heat-shrinkable label has a tubular shape, in which both end portions of a heat-shrinkable polyvinyl chloride-based film or a heat-shrinkable polystyrene-based film are bonded to each other with a solvent composition. The solvent composition contains at least one organic solvent selected from the group consisting of tetrahydrofuran (THE), methyl ethyl ketone (MEK) and ethyl acetate, and at least one resin selected from the group consisting of polyester, polypropylene and hydrogenated petroleum resin, and the end portion bonded has a peel strength of 2 N/15 mm or more.

Provided are primer formulations for solvent cement bonding comprising cyclopentanone and, optionally, at least one additional organic solvent. The primer formulations are effective for solvent cement bonding plastic components together, wherein the plastic components may include ABS, PVC, or CPVC pipes and/or fittings.
