A coating composition is based on a polyester mixed with an alkyl-etherified melamine formaldehyde. The coating composition is partially cured in a first stage to provide a thermoformable partially cured, tack-free, non-blocking, coating layer, followed by application to generally a contoured substrate and thermoforming to conform thereto. The contoured partially cured coating layer is then heat cured to form a cured coating. A hydroxyl-terminated polyoxetane containing repeat units derived from oxetane monomers having one or two pendent &#x2014;CH&#x2014;O&#x2014;(CH)&#x2014;Rf groups, wherein Rf is partially or fully fluorinated, can be esterified with polyester-forming reactants to form a fluorinated polyoxetane-modified polyester.

Coatings derived from polyester crosslinked with melamine formaldehyde

A method for preparing a substrate having an adherent, durable, flexible, and stain resistant layer. The layer is formed by applying a composition that includes (i) the reaction product of a polyester and a polyoxetane having at least one carboxylic acid end group and at least one pendant &#x2014;CH&#x2014;O&#x2014;(CH)&#x2014;Rf group and (ii) an amino resin curative. The substrate may be printed or embossed or both. The coated substrate has both stain resistant properties and dry erase properties.

A reactive fluorinated polymer having polyester and polyether segments is mixed with a reactive melamine resin to form a coating composition. The polyether segment can include monomeric units from an oxetane monomer having pendant fluorine groups that are linked to the oxetane via an ether group. The melamine resin can be a lower alkyl etherified melamine-formaldehyde. The composition can be disposed on a substrate and treated to form a laminate.

Fluorinated polymer and amine resin compositions and products formed therefrom

A fluorine containing polymer which acts as a wetting, flow or leveling agent, and has at least one polar group. The polymer has at least one pendant or ether side chain containing from about 1 to about 20 carbon atoms with at least 25% of the hydrogen atoms being replaced by fluorine atoms. The fluorinated polymers unexpectedly impart wetting, flow or leveling properties to a variety of coatings while producing little foam.

Monofunctional polyfluorooxetane oligomers and polymers are prepared by the cationic polymerization of fluorooxetane monomers with a monoalcohol. The fluorooxetane oligomers or polymers can be copolymerized with generally cyclic ethers. Alternatively, the polyfluorooxetane oligomer or polymer having a single hydroxyl end group can be functionalized with a variety of compounds so as to yield a functional end group such as an acrylate, a methacrylate, an allylic, an amine, etc., with the functionalized oligomer or polymer being suitable for use in radiation curable or thermal curable coating compositions. These functionalized polymers can be copolymerized and cured to provide improvements in wetting and surface properties that have previously been provided by migratory chemicals such as waxes and oils. The partially or fully fluorinated side groups of the fluorooxetanes are believed to be disproportionately present at the interfaces between the coating and the substrate and between the coating and the atmosphere.

Monofunctional polyfluorooxetane oligomers, polymers, and co-polymers are prepared by the cationic polymerization of fluorooxetane monomers with a monoalcohol. In addition to serving as an initiator, the monoalcohol can also serve as a solvent for the fluorooxetane or other monomers to produce oligomers, polymers, or copolymers having low cyclic content. Suitable comonomers generally include various cyclic ethers. The polyfluorooxetane oligomer, polymer, or copolymer having a single hydroxyl end group can be functionalized with a variety of compounds so as to yield a functional end group such as an acrylate, a methacrylate, an allylic, an amine, etc., with the functionalized oligomer or polymer being suitable for use in radiation curable or thermal curable coating compositions. These functionalized polymers can be copolymerized and cured to provide improvements in wetting and surface properties.

A method and apparatus for continuously seaming cured EPDM membrane to form a composite sheet of predetermined width and indefinite length. The method includes the steps of providing at least two rolls of cured EPDM membrane having longitudinal marginal edges and feeding the cured EPDM membrane from the at least two rolls in a first direction. The longitudinal marginal edges of the cured EPDM membranes are positioned in an overlapping relationship as the cured EPDM membranes are fed in the first direction and then the overlapping longitudinal marginal edges are continuously seamed to form a composite sheet of indefinite length.

A composition comprises an oxetane oligomer or polymer or copolymer block wherein each repeat group has at least one ether side chain which is terminated by a fluorinated aliphatic group and optionally with the proviso that at least two different repeat units of the oligomer or polymer or copolymer have different Rgroups. The oxetane block is connected to a hydrocarbon polymer block derived from a mono or polyhydroxyl initiator. The terminal fluorinated alkyl groups impart good stain resistance to the oligomer or polymer or copolymer. In another embodiment, a fluorinated aliphatic or alkyl alcohol is reacted with an amino dicarboxylic acid with the reaction product thereof being subsequently grafted to a maleated polyolefin or a maleated polymer derived from a vinyl substituted aromatic monomer. The fluorinated alcohol also imparts good stain resistance to the grafted copolymer. Both compounds can be utilized as an additive in polymers as for example various polyolefins.

A co-mingled polyurethane-polyvinyl ester composition can be used as a coating, which has good scratch, mar and solvent resistance. The coating is derived from a waterborne polyurethane solution containing free radically polymerizable monomers such as acrylate, ultraviolet light initiators, and optionally urethane crosslinking agents. A process for forming the co-mingled polyurethane-polyvinyl ester composition comprises drying the waterborne polyurethane containing the polymerizable monomers therein and radiation polymerizing, as by ultraviolet light, the free radically polymerizable monomers on a substrate such as a plastic sheet to form a laminate. Subsequently, the laminate can be utilized to form a coating on a product as by thermoforming, where if urethane crosslinking agents are utilized, the polyurethane will be crosslinked.

The polyester polymer containing at least one polyoxetane block therein when reacted with an amino resin curative can be used as a coating on a substrate wherein the coating has dry erase properties. The coated substrate can be used as prepared or applied to yet other substrates.
