A coating composition includes: (a) (i) a thiol functional compound and (ii) an ethylenically unsaturated compound reactive with (i); (b) a catalyst that catalyzes a reaction between (i) and (ii); and (c) an odor masking agent that masks an odor of at least (i) the thiol functional compound. A method of forming the coating is also included.
Loupe and loupe unit
A loupe is bonded to a glasses-type holder to be worn around a head of a user. The loupe includes: a tube framework inserted into a hole or a cutout formed in the glasses-type holder and bonded with a UV adhesive; and a lens held in the tube framework. At least a portion at which the UV adhesive is applied in the tube framework is made of a resin not resistant to acetone and is covered with a paint resistant to acetone.
Low viscosity poly(alkynyl carbamate) polymers
An alternative polyurethane composition is provided which comprises a reaction product of an azidated polyol and a poly(alkynyl carbamate) prepolymer, wherein reaction occurs at a temperature of from 20° C. to 200° C., optionally in the presence of a Cu.sup.I-containing catalyst and wherein the poly(alkynyl carbamate) prepolymer comprises a reaction product of a polyisocyanate, an alkynol, and a glycol ether, wherein from 1 mol % to 33 mol % of isocyanate groups are reacted with glycol ether and the remaining isocyanate groups are reacted with the alkynol. The inclusion of glycol ethers into the polyisocyanate chain of the poly(alkynyl carbamate) prepolymer at a level of from 1 mol % to 33 mol %, is efficient in reducing the viscosity of the composition without compromising its performance in coatings, adhesives, sealants, films, elastomers, castings, foams, and composites made with the inventive alternative polyurethane compositions.

Methods of facilitating removal of a fingerprint
Bioactive coatings that include a base and a protein associated with the base for actively promoting the removal of organic stains are provided. In aspects, bioactive coatings that are stabilized against inactivation by weathering are provided including a base associated with a chemically modified enzyme, and, optionally a first polyoxyethylene present in the base and independent of the enzyme. The coatings are optionally overlayered onto a substrate to form an active coating facilitating the removal of organic stains or organic material from food, insects, or the environment.
Physical property improvement of polyurethanes
100% solids polyurethanes having improved physical properties in terms of Shore hardness, tear strength, elongation at break and/or tensile strength are realized through the introduction of 100% solids hydroxyl-functional acrylics in combination with the hydroxyl-functional polyether and 100% solids isocyanate-functional compounds. When an aromatic isocyanate is used, the isocyanate-reactive component includes from 5 to 70% by weight of a hydroxyl-functional polyether having a weight average molecular weight ranging from 180 to 6,500 g/mol, and 30 to 95% by weight of a hydroxyl-functional acrylic. When an aliphatic isocyanate is used, the isocyanate-reactive component includes from 40 to 70% by weight of a hydroxyl-functional polyether having a weight average molecular weight ranging from 180 to 6,500 g/mol, and 30 to 60% by weight of a hydroxyl-functional acrylic.
Polyurethane surfacing film
Surfacing films and related processes are provided. These films include a first clear coat layer comprising a first crosslinked polyurethane that is the reaction product of an isocyanate; a polyol selected from the group consisting of: a caprolactone polyol, polycarbonate polyol, a polyester polyol, acrylic polyol, polyether polyol, polyolefin polyol, and mixtures thereof; and a hydroxy-functional silicone poly(meth)acrylate; a second clear coat layer comprising a crosslinked polymer that is essentially free of hydroxy-functional silicone poly(meth)acrylate; a bulk layer comprising a thermoplastic polyurethane; and an adhesive layer. The provided films overcome the problem of migration of solvents and other impurities into the polyurethane bulk layer because the clear coat layer is cured, and solvents removed, prior to the coating of the polyurethane bulk layer. Manufacturing of these films can provide substantially faster line speeds and reduced waste.
Omniphobically coated fluid channels and related methods
The disclosure relates to an omniphobically coated fluid channel including a channel defining an interior channel surface and a flow volume, and a thermoset omniphobic composition as a coating on the interior channel surface. The thermoset omniphobic composition (such as an omniphobic polyurethane or epoxy composition) includes a thermoset polymer with first, second, and third backbone segments. The first, second, and third backbone segments can correspond to urethane or urea reaction products of polyisocyanate(s), amine-functional omniphobic polymer(s), and polyol(s), respectively, for omniphobic polyurethanes. Similarly, the first, second, and third backbone segments can correspond to urea or beta-hydroxy amine reaction products of polyamine(s), isocyanate-functional omniphobic polymer(s), and polyepoxide(s), respectively, for omniphobic epoxies. The thermoset omniphobic composition coating protects the underlying channel material (such as metal material) from corrosion, and it can further reduce the pressure drop of fluid flowing through the channel. The omniphobically coated fluid channel can be used as a component of a heat transfer apparatus.
