A surface-treating agent including a perfluoro(poly)ether group-containing silane compound and a perfluoro(poly)ether group-containing compound. The perfluoro(poly)ether group-containing compound contains a radical capturing group or a UV absorbing group in the molecule.

The present invention is directed to dirt and anti-microbial resistant articles that include a substrate, a powder coating applied to the substrate, the powder coating may include a cross-linked polymeric binder. The powder coating may include a blend of metal borate and a sulfur-containing benzimidazole compound, wherein the metal borate and sulfur-containing benzimidazole compound are present in a weight ratio ranging from about 75:1 to about 10:1. The powder coating may include fluorosurfactant and a fluorosurfactant may be applied to the powder coating in an amount ranging from about 0.01 g/m.sup.2 to about 4 g/m.sup.2. The powder coating may be formed using a liquid-based fluorosurfactant.

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.
