COATINGS INCORPORATING NON-FLUORINATED CLEANABILITY

ADDITIVES FIELD OF THE INVENTION

Non-fluorinated hydrophilic compounds are employed in

architectural coatings to provide surface effects to various articles.

BACKGROUND OF THE INVENTION

Fluorinated polymer compositions are used in the preparation of a wide variety of surface treatment materials to provide surface effects to substrates. Many such compositions are fluorinated surfactants which contain predominantly eight or more carbons in the perfluoroalkyi chain to provide the desired properties. Honda, et al., in Macromolecules, 2005, 38, 5699-5705 teach that for perfluoroalkyi chains of greater than 8 carbons, orientation of the perfluoroalkyi groups, designated Rf groups, is maintained in a parallel configuration while for such chains having 6 or less carbons, reorientation occurs. This reorientation is recited to decrease surface properties such as contact angle. Thus, compounds containing shorter perfluoroalkyi chains or having no fluorine content have traditionally exhibited lower performance. Fluoroadditives have also been used to improve cleanability of paints, including latex paints, which generally have poor stain and soil resistance.

Test Methods

Dosing of Polymer Additives in Paint and Test Panel Application

Additive compounds of the present invention are added to selected commercially available interior and exterior latex paints that are, prior to dosing, free of fluoroadditives. The sample is mixed using an overhead Cowles Blade stirrer at 300 rpm for 5 minutes. The mixture is then transferred to a glass jar, sealed and placed on a roll mill for at least 1 -2 hours to allow uniform mixing of the additive. The samples are then drawn down uniformly on a black Leneta Mylar® card (5.5" x 10") via a BYK- Gardner drawdown apparatus using 5 ml_ bird-applicator, to yield a wet paint film with a film thickness of 5 mils. The paint films are then allowed to dry at room temperature for 7 days to yield dry paint films with a film thickness of about 2.5 mils.

Test Method 1 . Evaluation of Water and Oil Repellencv via Contact Angle (CA) Measurement

Water and oil contact angle (CA) measurements are used to test for the migration of fluoroadditive to the surface of the paint film. Testing is performed by goniometer on 1 inch strips of Leneta panel coated with dried paint film. A Rame-Hart Standard Automated Goniometer Model 200 employing DROPimage standard software and equipped with an automated dispensing system, 250 μΙ syringe, and illuminated specimen stage assembly is used. The goniometer camera is connected through an interface to a computer, allowing the droplet to be visualized on a computer screen. The horizontal axis line and the cross line can both be independently adjusted on the computer screen using the software.

Prior to contact angle measurement, the sample is placed on the sample stage and the vertical vernier is adjusted to align the horizontal line (axis) of the eye piece coincident to the horizontal plane of the sample. The horizontal position of the stage relative to the eye piece is positioned so as to view one side of the test fluid droplet interface region at the sample interface.

To determine the contact angle of the test fluid on the sample, approximately one drop of test fluid is dispensed onto the sample using a 30 μΙ_ pipette tip and an automated dispensing system to displace a calibrated amount of the test fluid. For oil contact angle measurements, hexadecane is suitably employed, and deionized water is used for water contact angle measurements. Horizontal and cross lines are adjusted via the software in case of the Model 200 after leveling the sample via stage adjustment, and the computer calculates the contact angle based upon modeling the drop appearance. The initial contact angle is the angle determined immediately after dispensing the test fluid to the sample surface. Initial contact angles above 30 degrees are indicators of effective oil repellency. Test Method 2. Household Cleanability Ratings

The household cleanability test is based on ASTMD3450, which describes the method of cleanability for leneta stain on interior paints. This version of cleanability uses the same basic principles and primarily only changes the stains being applied to the paint. The test material (paint) is applied to a black, mylar panel and allowed to dry for 7 to 10 days. Application of stains is dependent on the stains selected. Crayon, marker, and pencil stains are applied by filling in an approximately one- inch block with even pressure. Liquid stains such as coffee, tea, and wine, are applied by holding the panel at an angle and using a pipette to evenly coat the stain. Lipstick stains are applied by using a ruler as a guide. Stains are allowed to sit for 30 minutes before being removed. The stains used are defined in Table 1 below.

Table 1. Stain Definitions

The test piece is placed horizontally on a Washability Test

Apparatus Cloth Holder, such as Model AG 8100 available from BYK- Gardner, Silver Spring, MD, clipped onto the machine, where the film is washed with a mild soap solution of 1 % JOY Soap for 25 cycles. The panel is rinsed with water and allowed to dry for several hours. The cleaned area is compared to the uncleaned area for a visual rating score according to Table 2 below. This visual scoring method was created through use of Six Sigma Methodology and has been made a certified method of rating. Half scores and quarter scores are used to help distinguish within a given sample set. A value "Combined Stain Ratings for Stains 1 -7" is the sum of all 7 rating scores.

An additional 1 g of water and FeCb were added, and the mixture was stirred until no active isocyanates were present. ARMEEN DM 18D (2.7 g), acetic acid (2.0 g) and water (300 g) were added. The mixture was homogenized twice at 6000 psi, and the solvent was removed via distillation.

SILSURF D212-CG was combined with SMA 1000 H in a ratio of 33:66 by solids weight and mixed together to form a mixture at 25% solids by weight and a pH of 8.9. The mixture was blended in a ratio of 90: 10 by solids weight with the stain release composition. The mixture was dosed into a 75-g paint sample according to the dosing procedure such that the final mixture contained 1 % by solids weight of the mixture. The resulting paint sample was tested according to the test methods above.

Example 127

Example 126 was repeated, using SILSURF Di-1017 (25.23 g) instead of SILSURF D212-CG.

Examples 128-129

Example 124 was repeated, using STS-30 (128) or CAPSTONE TR (129) instead of ZELAN CA-72.

Example 130

SILUBE CS-1 was combined with SMA 1000 H in a ratio of 33:66 by solids weight and neutralized with ammonium hydroxide to form a mixture at 25% solids by weight and a pH of 8.6. The mixture was dosed into a 75-g paint sample according to the dosing procedure such that the final mixture contained 1 % by solids weight of the mixture. The resulting paint sample was tested according to the test methods above.

Example 131

SILSURF D212-CG was combined with SMA 1000 H in a ratio of 33:66 by solids weight and mixed together by mechanical stirring to form a mixture at 45% solids by weight. The mixture was dosed into a 75-g paint sample according to the dosing procedure such that the final mixture contained 1 % by solids weight of the mixture. The resulting paint sample was tested according to the test methods above.

Example 132

Example 130 was repeated, without the addition of ammonium hydroxide, to form a mixture at 40% solids. Example 133

Example 132 was repeated, using the ratio of 42:58 by solids weight.

Examples 134-136

Examples 131 -133 were repeated, except the mixture was dosed into a 75-g paint sample according to the dosing procedure such that the final mixture contained 0.5% by solids weight of the mixture.

Example 137

SILUBE CS-1 was neutralized with sodium hydroxide to form a mixture at 25% solids by weight and a pH of 7. The mixture was dosed into a 75-g paint sample according to the dosing procedure such that the final mixture contained 0.01 % by solids weight of the mixture. The resulting paint sample was tested according to the test methods above. Example 138

Example 137 was repeated, except the mixture was dosed into a

75-g paint sample according to the dosing procedure such that the final mixture contained 0.75% by solids weight of the mixture.
