An epilamization agent containing at least one compound including at least hydrophobic and oleophobic moieties arranged to impart epilame properties to the compound, and at least one hydrophilic moiety arranged to make the compound soluble in aqueous medium, the hydrophilic moiety being linked to the compound by at least one cleavable group. A method for coating a substrate with epilame, including: preparing an aqueous epilamization bath by solubilising such an epilamization agent, placing the substrate in contact with the epilamization agent in the epilamization bath, separating the hydrophilic moiety from the epilamization agent by cleavage, rinsing the substrate to eliminate the hydrophilic residues from the hydrophilic moiety and drying.

Polymer compositions for coating of metal surfaces including moieties that interact with a metal atom in the metal surface and optionally containing antifoulant moieties. These polymer compositions provide lubricious coatings for medical devices, anticorrosion coatings for metal components, and antifoulant coatings for marine components such as propellers. The polymer composition is synthesized in a safe manner in which the synthesis components are added to a synthesis vat and there is no need for filtration or removal of waste materials in any step including the consumer use. As such this invention provides an environmentally sound approach to composition synthesis, formulation development, and consumer use.

A hybrid grease is provided having low coefficients of friction and high wear protection which is employable over a wide temperature range. The hybrid grease includes a combination of a grease based on a silicone oil in conjunction with a grease based on synthetic hydrocarbon oils, mineral oils or polyglycols. The hybrid grease may especially be used to lubricate joints in vehicle parts based on plastic-steel pairings.

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.

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.
