POLYOLEFIN COATINGS GENERAL: In environments that stress the need for corrosive protection, Bridgeport’s POLYOLEFIN coated products offer a high level of protection, while maintaining a much more environmentally-friendly final product than other coated materials on the market. On the basis of their polymer nature both powder coatings can be included in the same group, although they differ considerably in their performance. as a coupling agent in polymer composites, involves reacting polypropylene with maleic anhydride and peroxide initiator at elevated temperature in the solid state, Polymeric coating mixture, method for applying this coating mixture to a metallic base for protecting an edge or a part, protective layer, a base coated in this manner and the use thereof, Polyolefin compositions comprising bio-based starch materials, Easy-open container and container coating, Highly abrasion-resistant polyolefin pipe, Highly abrasion-resistant grafted polyolefin pipe, Process for preparing free flowing epdm particles, Method to form an aqueous dispersion of an ionomer-polyolefin blend, High-adhesion polyethylene powder coating, Aluminum article covered by maleic anhydride modification polymers, Polymer oxidation process and emulsion therefrom, Modification of crystalline propylene polymers, Reaction products of unsaturated dicarboxylic acids,anhydrides,esters with degraded poly - alpha - olefin polymers, Aqueous dispersion for coating and coated articles, Process for the grafting of monomers onto polyolefins, Method of obtaining polymeric coating on metal substrate, Modified chlorinated polyolefins, aqueous dispersions thereof and their use in coating compositions, Adhesive blends and composite structures comprising acid or anhydride modified PE + hope + polypropylene, Cross-linkable hot-melt adhesive and method of producing same, Solid coating composition for textile floor coverings, Precross-linked silicone elastomer particles with organopolymer shell as formulation constituent in powder coating materials, Blends containing polyethylene and an unsaturated polycarboxylic acid modified polyolefin, Coating compositions containing a polyoxide and process for preparing this, Filler-containing polypropylene resin composition and process for producing the same, Crosslinkable polymer powder and laminate, Thermosetting powder coating compositions containing flow modifiers, Concentrates suitable for the preparation of functionalized polyolefins and functionalization, Polypropylene resin composition containing filler, Chlorine-free and reduced chlorine content polymer and resin compositions for plastic bonding, Water-based one-pack-type coating composition and coated article, Uv curable non-chlorine adhesion improvers, Adhesion promoter compositions for polyolefin substrates, Water-based paint composition and coated article thereof, Coating composition for polyolefin resin and process for producing the same, Process for preparing finely divided polymers. of acetone in a large blender followed each time by suction filtration. After addition of the peroxide ;j 20 solution, the reaction mixture is allowed to reflux for 1 -hour. . Suitable free radical sources are, for example, peroxides such as ditertiary butyl peroxide, t-butyl peracetate, t-butyl perbenzoate, or 2,5-dimethyl-2,5-di(tertiary butylperoxy)hexane~ Suitable irradlation sources also include, for example, ' ultravlolet ligh~. It has a Gardner impact strength (in. Epoxy 2. Polyolefin is a type of polymer produced from a simple monomer olefin and its powder is composed of crystalline polyolefin material produced from olefins. . The powder obtained by grinding ; is sieved for 1 hour to obtain the portion that is <140 mesh in size.The <140 mesh powder is electrostatically sprayed, using a Gema AG Electrostatic Powder Spray ~pparatus at a potential of 60 kv., onto unprimed bonderized steel test panels. One such suitable high molecular welght poly-~-olefln is the highly crystalline polypropylene pre-pared accordlng to U. S. Patent 2,969,345.The poly-~-olefins are reacted with unsaturated polycarboxylic components such as unsatura~ed polycarboxylic acids, anhydrides or esters thereof at temperatures generally less than 300C., preferably from about 130-240, in the presence of free radical sources. Epoxy-Polyester Hybrid 3. For example, stabilizers, fillers and pigments are preferably added to the graft copolymers in extruders or Banbury mixers. For the nonpigmented material, coating the pellets with stabilizers from a solution thereof is qÃ¹ite satisfactory. : - : to polypropylene having ~ melt ~low of approximately 60 and d density of 0.915 g./cc., ~lsing the procedure of Example 2 except that the extrusion -temperature is 180C. are generally suitable to provide smooth fused powder coatings which have such properties as good appearance, flexibility, adhesion, toughness and impact strength. 6. A powder coating composition according to Claim 6 wherein said carboxylated polypropylene is a maleated polypropylene. The maleated polymer is allowed to air dry for 1 hour and then is dried for 48 hours in a vacuum oven at 60C. When cryogen:ically ground to less than about 20 mesh size powder, these carboxylated materials can be conveniently coated on substrates using a fluidized bedcoating process and, when ground to less than about 100 mesh size powder, can be electrostatically spray coated onto substrates such as metal panels including un primed steel or alumin~, and other such suitable chargeable substrates.
