Abstract:
Shielding coatings are applied to polymer substrates for selective metallization of the substrates. The shielding coatings include a primer component and a hydrophobic top coat. The primer is first applied to the polymer substrate followed by application of the top coat component. The shielding coating is then selectively etched to form an outline of a desired current pattern. A catalyst is applied to the patterned polymer substrate followed by electroless metal plating in the etched portions. The portions of the polymer substrate which contain the shielding coating inhibit electroless metal plating. The primers contain polyamines and the top coat contains hydrophobic alky organic compounds.

Abstract:
The present disclosure generally relates to retroreflective sheeting including a topcoat and to methods of making such sheeting. In some embodiments, the retroreflective sheeting includes (1) a first major surface that is a structured surface having a structure imparted by a plurality of prismatic cube corner elements; (2) a second major surface opposite the first major surface, the second major surface being substantially planar and including a polycarbonate; and (3) a topcoat adjacent to at least a portion of the second major surface and the topcoat including a solvent-based composition.
Abstract:
A microstructured article includes a nanovoided layer having opposing first and second major surfaces, the first major surface being microstructured to form prisms, lenses, or other features. The nanovoided layer includes a polymeric binder and a plurality of interconnected voids, and optionally a plurality of nanoparticles. A second layer, which may include a viscoelastic layer or a polymeric resin layer, is disposed on the first or second major surface. A related method includes disposing a coating solution onto a substrate. The coating solution includes a polymerizable material, a solvent, and optional nanoparticles. The method includes polymerizing the polymerizable material while the coating solution is in contact with a microreplication tool to form a microstructured layer. The method also includes removing solvent from the microstructured layer to form a nanovoided microstructured article.
Abstract:
A fabric carcass defines the base of a conveyor belt. A first polymer is coated or otherwise disposed over an exterior side of the fabric carcass to cure with a first layer thickness. The first polymer may be a polyvinyl chloride resin with a plasticizer additive to provide an added robustness to belt at a relatively low cost. Due to deterioration that may occur when certain polyvinyl chloride resins are used as the exterior surface of the conveyor belt, a second polymer is disposed over the cured layer of polyvinyl chloride to define an exterior surface that is configured for resiliently interfacing with a die press of a cutting or stamping station. The second polymer may be a polyester to provide improved resiliency and an exterior surface with better durability than the first polymer.
Abstract:
A composite hose assembly including a fluropolymer inner tube and a jacket circumferentially surrounding the fluropolymer tube. The jacket is formed from a plurality of plaits of fiberglass lace or other material. The jacket is then coated or infused with different resins along an axial length of the tube to impart varying degrees of flexibility along its length. A method of making the composite hose assembly includes: providing a fluropolymer inner tube, forming a jacket by circumferentially wrapping a plurality of plaits of fiberglass lace or other material around the fluropolymer tube, and infusing the plaits with different resins along its length to vary the flexibility.
Abstract:
Provided is a testing device including a flow path in which an analyte is flowed, wherein a composition containing a reagent reactive with the analyte and a lyophilic resin is placed at one position or a plurality of positions of the flow path.
