Claims38
A polymer coating on a substrate based on an aqueous polymer coating composition comprising micronized polymer particles and a surfactant with HLB value greater than 9.
An aqueous polymer coating composition comprising micronized polymer particles and a surfactant with HLB value >9, wherein 90% of polymer particles (based on volume) have particle size below 45 micrometers.
A polymer thin film formed from an aqueous polymer coating composition comprising micronized polymer particles and a surfactant with HLB value >9.
An article comprising a substrate selected from the group consisting of wood, plastic, metal, glass and mixtures thereof, and at least one coating thereon formed from micronized particles selected from the group consisting of polyetherimide, polyethersulfone, blends thereof, and combinations thereof.
A process for forming a coating or thin film of a polymer with reduced release of volatile organic components (VOC), the process comprising wetting a substrate with an aqueous dispersion of micronized thermoplastic powder having a spherical morphology and an average particle diameter of less than or equal to 45 microns, and thereafter heating the thermoplastic powder to a temperature of at least 300 degrees Celsius for at least 15 minutes.
