Abstract:
A method for making a coating composition by mixing one or more latex polymers and an aliphatic epoxy resin system having an epoxy equivalent weight less than 1000 and being distinct from the one or more latex polymers to provide an aqueous first component, and providing a second component having reactive groups that can react with the one or more epoxy resins. A mixture of the first and second components provides a film-forming curable coating composition that may be used on substrates including cement, cement fiberboard, wood, metal, plastic, ceramic, glass and composites.
Abstract:
Disclosed are an ink composition and a method for forming embossments using the ink composition. Accordingly, a process of removing a clear residue on the printed pattern in the related arts may be eliminated. In particular, the ink composition for improving formation of embossment may include: a silane-modified polyacrylate resin in an amount of about 10 to 40 wt %; a silicone-modified polyacrylate resin in an amount of about 50 to 80 wt %; a silicone oil-type additive in an amount of about 3 to 7 wt %; and a silicone oil compound-type additive in an amount of about 5 to 15 wt %. The ink composition has substantially reduced surface tension to provide excellent water-repellency and oil-repellency. As such, a clear paint may not be adhered to the printed pattern surface of the ink composition, but instead, the clear paint may be adhered to the non-printed surface, thereby forming an embossed pattern.
Abstract:
An optically clear biofouling resistant coating compositions specially formulated for very high light transmission and more particularly coating compositions which can be applied to marine instruments and sensors. The compositions provide a biofouling resistant coating on the surface of the marine instruments and sensors which prevents underwater organisms from adhering and growing on the surfaces of the structures over a long period of time.
Abstract:
Systems and methods for fabricating bodies (e.g., porous bodies) are described. Various aspects provide for reactors and the fabrication of reactors. Some reactors include surfaces that provide for heterogeneous reactions involving a fluid (and/or components thereof). A fluid may be a gas and/or a liquid. A contaminant in the fluid (e.g., a dissolved or suspended substance) may react in a reaction. A contaminant may be filtered from a fluid. Some reactors provide for independent control of heat transfer (between the fluid, the reactor, and the environment) with respect to mass transfer (e.g., fluid flow through the reactor).
Abstract:
Provided are robust paint coating systems on metal-coated plastic substrates and processes for forming such material systems as decorative components. An organometallic adhesion promoter is applied to a metal-coated plastic substrate. The metal coating comprises chromium (Cr), nickel (Ni) or combinations thereof. The organometallic adhesion promoter comprises (i) a transition metal selected from the group consisting of: zirconium (Zr), titanium (Ti), chromium (Cr), and combinations thereof, (ii) a first ligand complexed to the transition metal comprising an organofunctional group, and (iii) a second ligand complexed to the transition metal having a hydrolysable functional group. Then, one or more organic paint precursor materials are applied thereon. The hydrolysable functional group is capable of reacting with the metal-coated substrate and the organofunctional group with at least a portion of the organic paint precursor material to form a robust polymeric paint coating having a robust bond with the metal-coated plastic substrate below.
Abstract:
A new method for durably bonding layers of a functional material to surfaces physically and chemically bonds solid layer lubricants and other functional coatings to a substrate surface by first applying a bond layer of a selected substantially binder-free soft material onto the substrate surface by, for example, burnishing, and then applying the functional layer onto the bond layer. Example soft materials for the bond layer include soft oxides such as antimony trioxide and example solid layer lubricants include graphite, molybdenum disulfide and mixtures of such lubricants. The new method is a major improvement over conventional bonding or coating methods. The process is non-vacuum at ambient temperatures and requires no binders, adhesives, curing or baking. Lubricant performance is enhanced by orders of magnitude compared to conventional approaches. The method is inexpensive, environmentally friendly, applicable to almost any substrate material and scalable.
