Adhesive tape for bonding that can be detached without leaving residue and without damaging the surface of a substrate when stretched in a direction of a bond plane. An adhesive tape includes an elastomeric backing having opposing first and second surfaces an acrylate pressure sensitive adhesive disposed on at least one of the first and second surfaces of the backing. The backing includes a copolymer selected from the group consisting of polyether-polyester, polyether-polyamide, and a combination thereof and from about 20 to 60 wt % of a tackifier, based on the total weight of the backing. The backing has an elongation at break greater than 500%.

The present invention provides a water-based coating system that can be used to form durable, abrasion resistant, corrosion resistant, protective barriers on a wide range of substrates. The coating system is particularly effective for protecting metal-containing substrates, such as intermodal cargo containers, against corrosion. As an overview, the present invention provides water-based primer compositions suitable to form primer coats and topcoats on substrates. Desirably, the primer incorporates one or more chlorinated resins for excellent corrosion protection. These polymers not only provide excellent corrosion protection and but also show excellent adhesion to a wide range of substrate materials. The system also includes topcoat compositions enhance compatibility and adhesion to the primer and to provide enhanced application.

A resin composition is provided. The resin composition includes a thermosetting resin component and a filler, wherein the thermosetting resin component has a dissipation factor (Df) of not higher than 0.006 at 1 GHz, and the filler is selected from the following group: strontium titanate, calcium titanate, barium titanate, magnesium titanate, combinations thereof and the sintered material of any of the combinations. The filler is doped or not doped with one or more elements selected from silicon, cobalt, nickel, manganese, and rare earth elements. The average particle size (D50) of the filler ranges from about 2 μm to about 10 μm. The amount of the filler is about 10 parts by weight to about 600 parts by weight per 100 parts by weight of the thermosetting resin component.

Embodiments of the disclosure include lubricious coatings. In an embodiment the disclosure includes a lubricious coating for a medical device including first and second coated layers. The first coated layer is between the second coated layer and the device surface and includes a vinyl pyrrolidone polymer and a photo reactive group. The second coated layer is in direct contact with the first coated layer and is a top coating that includes an acrylic acid polymer. The second coated layer can optionally include photoreactive groups. The coating was found to have a very low number of particulates (e.g., 10 μm or greater) which is very desirable for in vivo use.
摘要:
A process for the coating of surfaces of a metallic component to be formed by contacting the surfaces of the metallic component prior to forming operation with an aqueous composition containing 80% by weight of at least one organic film-forming ionomeric polymer or copolymer, whereby the total organic polymeric material has an average acid number in the range from 20 to 300, optionally at least one further organic film-forming polymer different from the organic film-forming ionomeric polymer or copolymer; optionally a neutralizing agent; a low temperature corrosion inhibiting cross-linking agent and water. The pH of the aqueous composition at the beginning of the coating process is in the range from 6 to 10.5.
