Diamon-Fusion International Reveals The Benefit Of Sliding Angle When Evaluating “Easy-To-Clean” Protective Coatings
Diamon-Fusion International (DFI), Global Developer And Exclusive Licensor Of Patented Hydrophobic Nanotechnologies, Announced Today A New Program To Educate The Industry About The Significant Correlation Between Sliding Angle And Performance Of “Easy-To-Clean” Protective Coatings. Combining Sliding Angle With The Traditional Contact Angle Measurement Provides A Much More Reliable Picture Of How These Coatings Will Perform, According To Russell Slaybaugh, Vice President And General Manager Of DFI.
IRVINE, CALIF.,—Thursday, September 4, 2014—While both Contact Angle and Sliding Angle individually are informative measurements of the core benefits of “Easy-to-Clean” coatings, each alone is only half of the equation. When considered together they become much more powerful. A higher Contact Angle tells relatively how much less a surface will be stained, because the water that does stick will be repelled and will dry in smaller spots producing smaller stains. A lower Sliding Angle indicates how much less often you’ll need to clean, because the less water that sticks to the surface, the fewer stains will occur. Additionally, a lower Sliding Angle also indicates that any spots that do occur will be relatively easier to remove, because it is more difficult for things to stick. When evaluated together a complete measurement of how “easy to clean” the coating is revealed. Until now the glass industry as a whole has only considered half of the equation for hydrophobic protective coatings by evaluating only the Contact Angle, however Sliding Angle is just as, if not more, important in evaluating performance.
“Since the dawn of time, forward-thinking business managers around the world have known if you want to truly understand performance, you need to find an objective way to measure it,” shared Russell Slaybaugh, Vice President and General Manager of DFI. “The key to making proper comparisons is ensuring the measurements and testing methods are the same. It is often the case that as industries grow, it is necessary to introduce new measurements to properly evaluate and compare performance. We now know that historically the glass industry has only evaluated half of the equation. Now, by combining Contact Angle with Sliding Angle, the glass industry for the first time will see the whole equation and its significance when judging performance. By including Sliding Angle when describing the performance of their protective coating, manufacturers can now give potential customers a more accurate picture of the benefits their coatings provide.”
Did you know there are two important measurements for a low-maintenance hydrophobic protective coating? Watch the video tutorial below for a brief explanation of these two important measurements: Contact Angle and Sliding Angle. For a more detailed explanation on the Contact Angle and Sliding Angle, read the rest of this press release or our article on Evaluating The Performance Of Protective Coatings.
Contact Angle – Why It’s Important
In the late 1990’s, in an emerging field of coatings that made glass harder to stain and easier to clean, a few competitors started using Contact Angle measured in degrees to compare the water repellency of these coatings. This was because one of the main characteristics of these coatings is that they are all water-repellent or hydrophobic. It was believed that the more water-repellent a surface is the more water will bead off and so the minerals and contaminants (such as body oils, soap, etc.) that water carries cannot be deposited on the glass. Unfortunately, we’ve learned that this is not always true, so Contact Angle is not enough.
Sliding Angle – The Other Half of the Equation
In its simplest explanation, Sliding Angle measures the “slickness” of a surface – whether coated or not. A drop of water – the size of which is determined by the standard test – is placed at one end of the sample of coated glass. Then the sample is tilted until the drop of water begins sliding. The tilt of the glass at that very instant is the Sliding Angle. The lower the Sliding Angle the slicker the surface. The slicker the surface, the less things like water and contaminants can stick. As it measures how easy or difficult it is for things to stick to the surface, Sliding Angle therefore can be that credible proxy to measure “Easy-to-Clean” that the industry needs. So the lower the Sliding Angle of a surface, the easier it is to clean.
By providing both Contact Angle and Sliding Angle for several different coatings, consumers receive the whole picture of how Easy-to-Clean each coating is, ensuring consumers have the right information in order to make an informed decision.
