Abstract: A curable film and a cured product obtained by curing the curable film are disclosed. The curable film contains, as essential components, hollow glass microspheres and a rubber composition containing at least one diene-based rubber. The curable film is thin and has excellent processibilities. The cured product has desirable dielectric and thermomechanical characteristics that are suitable to be used as a dielectric material for printed circuit boards, especially for multilayer printed circuit boards and high-density interconnect printed circuit boards.

Abstract: A composition for curable films, a curable film made thereof, and a cured product obtained by curing the curable film are disclosed. The curable film contains fused silica and/or hollow glass microspheres, a rubber composition containing at least one diene-based rubber, and a toluene soluble maleimide resin. The curable film is thin and has excellent processibilities. The cured product has desirable dielectric and thermomechanical characteristics that are suitable to be used as a dielectric material for printed circuit boards, especially for multilayer printed circuit boards and high-density interconnect printed circuit boards.

Abstract: Molecular hydrogen has been shown to have cosmetic and medicinal benefits. However, delivery methods have been ineffective in aiding the body in receiving and absorbing the hydrogen. This device has a dry chemical separated from a solution. Both the dry chemical and the solution are housed in a container. The container has a hydrogen impermeable top outer layer and a hydrogen permeable bottom layer. Once initiated, a determined and controlled chemical reaction generates molecular hydrogen within the container. The hydrogen then exits the device through the hydrogen permeable side of the device that is facing the skin. The device carries a low risk of toxicity while providing cosmetic and medicinal advantages.

Abstract: A UV absorber-comprising urethane acrylate of formula (I) and a HALS-comprising urethane acrylate of formula (I): wherein, UVA is a UV absorber molecule that has a hydroxyl or an amine group reactive with isocyanate, HALS is a HALS molecule that has a hydroxyl or an amine group reactive with isocyanate, and Acr is an acrylate or methacrylate group attached through a linker selected from the group 2-isocyanatoethyl acrylate, 2-isocyanatoethyl methacrylate, and 1,1-Bis(acryloxymethyl)ethyl isocyanate. The UV absorber-comprising urethane exhibits a UV absorption maximum between 300 and 360 nanometers.

Abstract: A heat and/or UV/LED activated single or double-sided tape is configured to seal multiple sheets of single or multilayer composite film with the film including an outer fluoropolymer layer. A repair kit includes a single-sided and/or double-sided heat and UV/LED activated adhesive tape, portable surface treater, and portable heat/UV/LED generating device. The single-sided and/or double-sided heat and UV/LED activated adhesive tape is useful in the manufacturing of architectural applications and in repair of architectural applications.

Abstract: Extraction method for recovering metals. Phosphoric acid is contacted with an extractant suspension of solid particulate material comprising a para- or ferromagnetic material core surrounded by an outer shell of a chelating polymer whereby a metal is the solution is adsorbed on the chelating polymer, thereby removing it from the phosphoric acid solution. The metal-containing solid particulate material is magnetically separated from the solution and the metal is stripped from the solid particulate material for reuse.
