A floor plank having a rigid, composite core having an upper side and a underside, the core being thermally stable and formed of PVC and calcium carbonate material that does not include ortho-phthalates, a wood veneer having a lower surface on the upper side of the core and further including an exposed surface, a protective coating on the exposed surface of the wood veneer, the protective coating formed of catalyzed polyurethane having aluminum oxide particles, and a thermo-acoustic cushion coating on the back surface of the core. A method of making is also provided.

The present teachings generally provide curable polysiloxane compositions including a base resin including a surface active polymer. Articles of manufacture including the curable polysiloxane compositions and slippery coatings and materials also are provided. The compositions may be used to provide slippery, lubricious, or repellent materials and coatings and may provide anti-fouling function. The compositions can provide anti-fouling or foul-release function on open surfaces, internal surfaces, membranes; to provide pinning free or low contact angle hysteresis surfaces; to provide homogeneous interface to suppress nucleation; to provide a barrier layer such as anti-corrosion; to provide anti-stain, anti-smudge, anti-fingerprint, anti-soil function.

Bioactive coatings suitable for facilitating removal of a fingerprint when contacting the coating 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. Also provided are processes of facilitating fingerprint removal.

An asymmetrically substituted polyorganosiloxane comprising at least one or more siloxane blocks and different reactive groups at each end of the siloxane chain, e.g. an alkoxysilyl, alkenyl, epoxy, hydroxyaromatic or an ionic substituent. Each polyorganosiloxane block has substantially a monomodal chain length distribution and is suitable for the use as a surface modifying agent for organic or inorganic particles, as a surface active material, and/or as a compatibilizer in compositions having more two or more non-miscible phases.

The present disclosure provides for a coating composition system suitable for forming a stain resistant and soft tactile texture coating onto a variety of substrate materials including plastic materials, metal materials, ceramic materials, and concrete materials. The coating composition system can be cured under mild curing conditions, and provides the resulting coating with excellent properties in terms of adhesion to the substrates, strength, and abrasion resistance. The present disclosure also provides for a method for preparing the coating composition system, and the use thereof.

Durable, anti-fouling, crosslinked zwitterionic coatings that are grafted to the surface of a substrate through covalent bonding are disclosed. When exposed to a light source, zwitterionic monomers react with a crosslinker and with activated radicals at the surface of the substrate, simultaneously forming the crosslinked zwitterionic coating and anchoring it to the surface of the substrate. Photomasking techniques can be used to micropattern the zwitterionic coatings. The zwitterionic coatings can be applied to a variety of substrates, including medical devices and systems.

A fluoroacrylic compound of formula (1) which, when added to an actinic-ray-curable composition, can impart excellent liquid repellency, antifouling properties, and wear resistance.

A coating film and a method for forming the same are provided. The coating film controls reduction in repellency of hydrophobic fine particles and increases rub fastness of the coating film. The coating film includes a ground layer containing thermoplastic resin (chlorinated polyolefin or acid modified chlorinated polyolefin, for example) and an upper layer containing hydrophobic fine particles (hydrophobic silica particle or silicone resin particle, for example) formed on the ground layer. Parts of the hydrophobic fine particles contained in the upper layer are buried in the ground layer.

A water-repellent coating composition, and particularly, a water-repellent coating composition having improved adhesion and durability by including a phosphoric acid or a phosphoric acid-based compound, is provided.
