The present utility model provides an easy-to-clean protective film, which belongs to the technical field of protective films for vehicles and other vehicles, and can solve the problems that lasting scratches are easily caused to the existing vehicle coatings and surface stains are not easy to clean. The easy-to-clean protective film provided by the present utility model comprises a polyvinyl chloride (PVC) bottom film and an easy-to-clean layer consisting of silicon dioxide particles, wherein the water contact angle of the easy-to-clean layer is small and thus the adhesive force of dust and oil stains can be reduced. After the surface of the easy-to-clean layer is contaminated by dust and oil stains, the dust and oil stains can be easily cleaned with a simple cleaning. The easy-to-clean protective film provided by the present utility model is suitable for use as protective coatings of various substrates, especially for attachment to the body surfaces of vehicles such as automobiles.

Easy-to-clean protective film and substrate assembly

A coating composition is disclosed comprising: (i) a non-zwitterionic compound comprising sulfonate-functional groups and (a) alkoxysilane groups and/or (b) silanol-functional groups; (ii) alcohol and/or water; and (iii) a tetraalkoxysilane, oligomers thereof, lithium silicate, sodium silicate, potassium silicate, silica, or combinations thereof.

Sulfonate-functional coatings and methods

A coating composition which imparts antifog properties to substrates coated therewith. The coating compositions are removable and utilize nanoparticles functionalized with epoxy groups. The removable coating compositions are particularly useful on personal protection equipment such as face masks, shields, and protective glasses.

Removable antifogging coatings, articles, coating compositions, and methods

A coating composition which imparts antifog, antireflective, easy-cleaning, and/or antistatic properties to substrates coated therewith. The coating compositions utilize nanoparticles functionalized with amine groups and/or protected amine groups, and amine-reactive groups.

Hydrophilic coatings, articles, coating compositions, and methods

A coating composition is described comprising: (i) a zwitterionic compound comprising sulfonate-functional groups and alkoxysilane groups and/or silanol-functional groups; (ii) alcohol and/or water; and (iii) a tetraalkoxysilane, oligomers thereof, lithium silicate, sodium silicate, potassium silicate, silica, or combinations thereof, along with coated articles and methods of using.

A method of coating with an aqueous coating composition having a pH &#x3c;5 of silica nanoparticles having a, average particle diameter of &#x2266;40 nm, silica nanoparticles having an average particle diameter of &#x2267;50 nm, and a tetraalkoxysilane. The resulting coatings are substantially uniform in thickness, durably adheres to the substrate, and provides antireflection and or hydrophilic surface properties to the substrate.

Silica coating for enhanced hydrophilicity/transmittivity

A coating composition is described comprising: (i) a zwitterionic compound comprising sulfonate-functional groups and alkoxysilane groups and/or silanol-functional groups; (ii) alcohol and/or water; and (iii) a tetraalkoxysilane, oligomers thereof, lithium silicate, sodium silicate, potassium silicate, silica, or combinations thereof, along with coated articles and methods of making and using.

A coating composition which imparts antifog, antireflective, easy-cleaning, and/or antistatic properties to substrates coated therewith. The coating compositions utilize nanoparticles funtionalized with amine groups and/or protected amine groups, and amine-reactive groups.
