Definitions

  • This invention relates to chemical compositions comprising one or more urethane oligomers and coating compositions comprising at least one solvent and the chemical compositions of the present invention. When applied as a coating, these urethane-based chemical compositions impart durable stain-release characteristics.
  • This invention also relates to articles comprising a substrate and on this substrate is a cured coating derived from the coating compositions of the present invention. The cured coating can impart stain-release characteristics to the substrate and resist being worn-off due to wear and abrasion. In another aspect, this invention relates to a process for imparting stain-release characteristics to substrates.
  • fluorochemical compositions on fibers and fibrous substrates, such as textiles, paper, and leather, to impart oil- and water-repellency and soil- and stain-resistance is well known in the art. See, for example, Banks, Ed., Organofluorine Chemicals and Their Industrial Applications, Ellis Horwood Ltd., Chichester, England, 1979, pp. 226-234.
  • fluorochemical compositions include, for example, fluorochemical guanidines (U.S. Pat. No. 4,540,497, Chang et al.), compositions of cationic and non-cationic fluorochemicals (U.S. Pat. No.
  • compositions containing fluorochemical carboxylic acid and epoxidic cationic resin U.S. Pat. No. 4,426,466, Schwartz
  • fluoroaliphatic carbodiimides U.S. Pat. No. 4,215,205, Landucci
  • fluoroaliphatic alcohols U.S. Pat. No. 4,468,527, Patel
  • fluorine-containing addition polymers copolymers, and macromers
  • fluorochemical compositions such as the fluorine-containing addition copolymers of U.S. Pat. No. 6,037,429, may be used on hard surfaces, including for example, ceramics, stone, masonry, wood.
  • U. S. Pat. Nos. 5,414,102 and 5,424,474 suggest that certain fluorine-containing phosphate esters can be used on hard surfaces, such as, ceramics, stone, masonry, wood, and plastics to repel water, grease, oil, and dirt.
  • fluorochemical compositions typically have been coated on hard substrates by means of aqueous emulsions.
  • fluorochemical compositions In coating on hard surfaces, durability of the coating of fluorochemical compositions is a concern. In many cases the fluorochemical compositions exhibit poor durability because the majority of the coated hard surface area is exposed to wear and abrasion from use, cleaning, and the elements. Due to this exposure, the coated composition can be worn-off leaving the hard surface unprotected.
  • Certain fluorine- containing urethanes have been found to provide superior abrasion durability and especially good water- and oil-repellency and stainproofing properties (U.S. Pat. No. 4,504,401). These previously known fluorine-containing urethane compositions can be solvent or water-based. In practice, all of the previously known fluorine-containing urethanes rely on perfluoroalkyl groups having an average of eight carbon atoms to achieve the desired repellency and stainproofing properties.
  • urethanes have been found to be especially durable, improved long-term durability is still needed for many hard surface applications.
  • a coating composition is needed that imparts longer lasting repellency and stain-proofing and is capable of withstanding repeated abrading and washing.
  • both solvent and water based fluorine-containing urethane compositions have been used to provide water- and oil-repellency to hard surfaces. Since organic solvents pose health, safety, and environmental concerns, the water-based compositions are particularly desirable.
  • the previously known compositions are typically aqueous dispersions or emulsions, not solutions; therefore, they require a high temperature cure to impart good repellency properties. In many cases, for example in floors and walls, high temperature curing is not practical or possible. For this reason there is a continuing need for urethanes that do not require costly and energy consuming high temperature cure conditions to impart good repellency properties. Therefore, urethane compositions, including those containing fluorine, that display increased water solubility are needed to eliminate the need for high temperature cure conditions, as well as to increase the ease of preparation and to provide more stable aqueous solutions.
  • the inventors recognized the need for shelf-stable chemical compositions, including those containing fluorine, that can successfully impart long term durability, uniform oil- and water-repellency and soil- and stain-resistance. These chemical compositions should be water and organic solvent soluble and should not require high temperatures for curing.
  • this invention relates to chemical compositions comprising one or more urethane oligomers of at least two repeating units selected from the group consisting of fluorine-containing urethane oligomers and long-chain hydrocarbon- containing urethane oligomers.
  • urethane oligomers comprise the reaction product of (a) one or more polyfunctional isocyanate compounds; (b) one or more polyols; (c) one or more monoalcohols selected from the group consisting of fluorochemical monoalcohols, optionally substituted long-chain hydrocarbon monoalcohols, and mixtures thereof; (d) one or more silanes; and optionally (e) one or more water- solubilizing compounds comprising one or more water-solubilizing groups and at least one isocyanate-reactive hydrogen containing group.
  • silanes are of the following formula (I):
  • R 1 is an alkylene, heteroalkylene, aralkylene, or heteroaralkylene bridging group; and each Y is independently a hydroxyl; a hydrolyzable moiety selected from the group consisting of alkoxy, acyloxy, heteroalkyoxy, heteroacyloxy, halo, and oxime; or a non-hydrolyzable moiety selected from the group consisting of phenyl, alicyclic, straight- chain aliphatic, and branched-chain aliphatic, wherein at least one Y is a hydrolyzable moiety.
  • oligomer means a polymer molecule that consists of at least two repeating (polymerized) units, but up to only a few (for example, from 2 to about 20) repeating units. Each repeating unit comprises a urethane group that is derived or derivable from the reaction of at least one polyfunctional isocyanate compound and at least one polyol.
  • the oligomer is terminated with (i) one or more perfluoroalkyl groups, one or more perfluoroheteroalkyl groups, or one or more long-chain hydrocarbyl groups; and (ii) one or more silyl groups.
  • compositions of the present invention comprising one or more urethane oligomers, impart stain-release characteristics and exhibit durability (i.e. they resist being worn-off) when exposed to wear and abrasion from use, cleaning, and the elements. Therefore, these compositions can be applied as coatings to a wide variety of substrates, for example, by topical application, to impart durable stain-release properties to the substrates.
  • the chemical compositions of the present invention can provide a uniform film. Applied as a coating, the chemical compositions of the present invention do not change the appearance of the substrate to which they are applied.
  • the chemical compositions of the present invention provide durable stain-release properties comparable to or better than those imparted by the corresponding lower molecular weight compositions containing only the fluorine-containing or long-chain hydrocarbon urethane compound with no repeating unit.
  • the chemical compositions of the present invention there is no need for high temperature curing; they can be cured (i.e., dried) at ambient temperature.
  • Certain preferred embodiments of the chemical compositions of the present invention include chemical compositions derived from one or more water-solubilizing compounds comprising one more water-solubilizing groups and at least one isocyanate- reactive hydrogen containing group. These preferred embodiments exhibit water solubility, while at the same time providing surprisingly good stain-release properties. These embodiments include, for example, those chemical compositions comprising a urethane oligomer containing one or more solubilizing groups.
  • the solubilizing groups include carboxylate, sulfate, sulfonate, phosphate, phosphonate, ammonium, quaternary ammonium, and the like.
  • compositions of the present invention include those compositions comprising terminal R f groups having from two to six carbons, preferably from three to five carbons, and more preferably four carbons. Even with Rf groups that are relatively short (i.e. less than eight carbons), these chemical compositions, surprisingly, exhibit excellent stain-release. Although compositions comprising lower fluorine content are less expensive, R f groups shorter than eight carbons typically have been overlooked by those of skill in the art because they have been known to impart inferior oil- and water-repellency and stain resistance.
  • fluorochemical surfactants contain perfluorooctyl moieties. These surfactants ultimately degrade to perfluorooctyl- containing compounds. It has been reported that certain perfluorooctyl-containing compounds may tend to bio-accumulate in living organisms; this tendency has been cited as a potential concern regarding some fluorochemical compounds. For example, see U.S. Patent No. 5,688,884 (Baker et al.). As a result, there is a desire for fluorine-containing compositions which are effective in providing desired surfactant properties, and which eliminate more effectively from the body (including the tendency of the composition and its degradation products).
  • compositions of the present invention which contain perfluorobutyl moieties, when exposed to biologic, thermal, oxidative, hydrolytic, and photolytic conditions found in the environment, will break down to various degradation products.
  • compositions comprising perfluorobutylsulfonamido moieties are expected to degrade, at least to some extent, ultimately to perfluorobutylsulfonate salts. It has been surprisingly found that perfluorobutylsulfonate, tested in the form of its potassium salt, eliminates from the body much more effectively than perfluorohexylsulfonate and even more effectively than perfluorooctylsulfonate.
  • perfluorobutylcarbonate which is expected to be the ultimate degradation product of compositions comprised of perfluorobutylcarbonyl and perfluorobutyoalkyl moieties.
  • compositions comprising terminal long-chain hydrocarbon groups having 10 to 18 carbons include those compositions comprising terminal long-chain hydrocarbon groups having 10 to 18 carbons.
  • Long-chain hydrocarbon groups typically have been known to impart poor oil repellency; however, the chemical compositions of the present invention comprising terminal long-chain hydrocarbon groups having 10 to 18 carbons impart good stain-release properties.
  • long-chain hydrocarbon groups having chain lengths of 12 to 16 carbons are preferred, 12 to 14 carbons being more preferred, and 12 carbons being most preferred.
  • Another embodiment of the present invention relates to a coating composition
  • a coating composition comprising a solution comprising the chemical composition of the present invention and a solvent.
  • this coating composition provides a uniform distribution of the chemical composition on the substrate without altering the appearance of the substrate.
  • a high temperature cure is not required to provide this coating; the coating composition can be cured (i.e. dried) at ambient temperatures.
  • This invention also relates to an article comprising a substrate having one or more surfaces and on one or more surfaces of this substrate is a cured coating derived from at least one solvent and a chemical composition of the present invention.
