Abstract
A method of adhering a particulate material, such as a hydrocarbon adsorbent material and/or a catalytic material, to a plastic surface, and products comprising the adhered material are disclosed.
Claims22
An adsorbent and/or catalytic article, said article comprising
- at least one plastic surface and an adhered material on at least a portion of said plastic surface, wherein said adhered material comprises an adherent,
- an organic binder and
- a particulate material selected from the group consisting of an adsorbent material, a catalytic material and combinations thereof,
- wherein said adherent is an adhesion promoter,
- wherein said adhesion promoter is a chlorinated polyolefin or a maleated polyolefin, and
- wherein said plastic is selected from the group consisting of polypropylene, nylon-6, nylon-6,6, aromatic nylon, polysulfone, polyether sulfone, polybutylene terephthalate, polyphthalamide, polyoxymethylene, polycarbonate, polyvinylchloride, polyester, and polyurethane.
3 more elements
A method for adhering a particulate material to a plastic surface, said method comprising
- treating a plastic surface with an adherent to form a treated plastic surface, and
- depositing a composition comprising an organic binder and a particulate material on said treated plastic surface to form a coated plastic surface having improved adhesion of said particulate material to said plastic surface,
- wherein:
- said adherent is an adhesion promoter
- said adhesion promoter is a chlorinated polyolefin or a maleated polyolefin,
- said particulate material is selected from the group consisting of an adsorbent material, a catalytic material and combinations thereof, and
- said plastic is selected from the group consisting of polypropylene, nylon-6, nylon-6,6, aromatic nylon, polysulfone, polyether sulfone, polybutylene terephthalate, polyphthalamide, polyoxymethylene, polycarbonate, polyvinylchloride, polyester, and polyurethane.
4 more elements
A method for adhering a particulate material to a plastic surface, said method comprising
- depositing a composition comprising an organic binder, an adhesion promoter and a particulate material on a plastic surface to form a coated plastic surface having improved adhesion of said particulate material to said plastic surface,
- wherein:
- said particulate material is selected from the group consisting of an adsorbent material, a catalytic material and combination thereof,
- said plastic is selected from the group consisting of polypropylene, nylon-6, nylon-6,6, aromatic nylon, polysulfone, polyether sulfone, polybutylene terephthalate, polyphthalamide, polyoxymethylene, polycarbonate, polyvinylchloride, polyester, and polyurethane, and
- said adhesion promoter is a chlorinated polyolefin or a maleated polyolefin.
2 more elements
A method for adhering a particulate material to a molded plastic article, said method comprising
- applying an adhesion promoter to an inner surface of a mold cavity,
- introducing plastic into the mold cavity to form a treated molded plastic article, and
- removing said treated molded plastic article from said mold cavity,
- wherein a composition comprising an organic binder and a particulate material is adhered to said treated molded plastic article by:
- i) depositing said composition on said adhesion promoter-treated inner surface of said mold cavity prior to said introducing step;
- ii) depositing said composition on said treated molded plastic article after said removing step;
- or
- iii) combining said composition with said adhesion promoter and then applying to the inner surface of a mold cavity;
- thereby forming a coated molded plastic article having improved adhesion of said particulate material to said molded plastic article,
- wherein:
- said particulate material is selected from the group consisting of an adsorbent material, a catalytic material and combinations thereof, and
- said plastic is selected from the group consisting of polypropylene, nylon-6, nylon-6,6, aromatic nylon, polysulfone, polyether sulfone, polybutylene terephthalate, polyphthalamide, polyoxymethylene, polycarbonate, polyvinylchloride, polyester, and polyurethane.
