摘要:
A method comprising heating to elevated temperature a ceramic substrate having thereon a sequence of coatings of pigmented coating compositions wherein each of said pigmented coating compositions comprises: (a) reactive organic resin which is polyhydroxy-functional, polyepoxy-functional, or both epoxy-functional and hydroxy-functional; (b) reactive wax; (c) color-imparting pigment; and (d) blocked polyisocyanate; wherein: (e) the pigmented coating composition of at least one coating of the sequence is substantially free of amino-functional curing agent; and (f) the pigmented coating composition of at least one other coating of the sequence further comprises amino-functional curing agent; to crosslink all of the pigmented coating compositions of the coatings of the sequence and to adhere the sequence to the ceramic substrate. The preferred ceramic substrates are glass bottles.The outermost coating of the sequence may optionally be overlain with a coating of substantially clear overcoating composition which comprises reactive organic resin which is polyhydroxy-functional, polyepoxy-functional, or both epoxy-functional and hydroxy-functional. Upon heating to the elevated curing temperature, the substantially clear overcoating composition is crosslinked together with the pigmented coating compositions.
摘要:
A composition that includes a fluorine-containing copolymer containing at least 30 mol % of residues having the following alternating structural unit: —[DM—AM]— where DM represents a residue from a donor monomer having the following structure (I): where R1 is linear or branched C1 to C4 alkyl; R2 is selected from methyl, linear, cyclic or branched C1 to C20 alkyl, alkenyl, aryl, alkaryl and aralkyl; and AM represents an acceptor monomer. The copolymer contains at least 5 wt. % fluorine. The composition may include co-reactive functional groups and may be a thermosetting composition, which can be used to coat a substrate. The thermosetting composition may be part of a multi-component composite coating composition that includes a base coat deposited from a pigmented film-forming composition and a substantially pigment free top coat applied over at least a portion of the base coat.

The invention provides a novel coating composition which includes: (a) a polyester-based resin component, (b) an epoxy component, (c) a crosslinker component, (d) a catalyst component, and (e) a diluent component. The polyester-based resin component includes at least one phosphatized polyester resin; and the epoxy component includes at least one phosphatized epoxy resin. These coating compositions are particularly suitable as primers, and especially as primers for use used in conjunction with coating composition which include fluorocarbon polymers. Also provided is a method of providing a substrate with a multilayer coating system. This method includes: (a) applying at least one layer of the aforementioned novel primer onto a substrate; and (b) applying at least one layer of a second coating composition over the primed substrate of step (a). When this method employs the use of a second coating composition which includes fluorocarbon polymers, the results is multi-layered coated substrate which, while having excellent weatherability properties, also has excellent formability properties.

摘要:
A method of designing the appearance of an article having steps of creating a digital file of a design configuration for an article, representing the design configuration on a computer screen, selecting or creating a color for a coating composition to be applied to the article, generating color data for the created color, merging the color data with the digital file of the design configuration, and displaying on the computer screen an image of the article coated with the colored coating composition. Accurate calibration of the color of the article on a computer screen allows for production of coated articles based on the generated color data. The color data is further transmitted to a formulation computer that determines the formulation for a coating composition exhibiting the color data. Output from the formulation computer may be directly transmitted to a production facility for coating articles with the coating composition.
摘要:
Polyphosphazenes are produced by polymerizing a silylated phosphinimine in the presence of an initiator, preferably an anionic initiator at temperatures below those typically necessary for such polymerization reactions. The polyphosphazenes obtained are suitable for use in the production of elastomeric and thermoplastic materials.
