Diamon-Fusion Test Data

Test Results

Test ResultsThe following are test results the Institute for Glass Science and Engineering at Alfred University, New York, an independent testing laboratory. The Institute routinely does testing for major companies like PPG and Kohler. Below is a summary of the most important findings of their tests.

The Institute’s report states that our improved process has a remarkably low coefficient of friction when the glass is wet. He states that when glass is wet, it is by far the "most dangerous period" with regards to the potential for damage. The report says that "we believe that the (main) usefulness of your coating lies in its maintenance of a low friction coating over the life of the glass". Below is a formula that puts into layman's terms the results of the coefficient of friction tests.

Contact Angle




Contact Angle Untreated Glass 14°
Improved Diamon Fusion® 106°
Our main competitor 91°

Contact angle is the scientific method of measuring the water repellency of a surface. The higher the number, the higher the water repellency of the surface. 

Contact Angle 15 Contact Angle 90 Contact Angle 118

The 2nd step of DFI's nanotechnology creates the 'capping' in the chain of atoms, which changes the molecular composition of the treated surface.

Note: Since these tests were performed, DFI's patented process has been improved and its contact angle has been measured at up to 118°, in addition to all other benefits that the nanocoating provides.

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 our article on Evaluating The Performance Of Protective Coatings

Coefficient of Friction: (with Glass indentor wet)



Untreated Glass 0.82
Improved Diamon Fusion® 0.13

To make the test results for coefficient of friction useful, we have used a formula that translates the data into the force required to cause damage to the surface. Assume that a load of 10 lbs. has been placed on the rider under static conditions, and that this is the lowest load that caused cracking (no dragging). Using the formula we can now calculate the load that would cause cracking to occur when the rider is dragged across the sample.

Load required to damage surface


Load (lbs)

Untreated Glass 0.37
Improved Diamon Fusion® 4.00

Note that when comparing wet vs. wet friction calculations indicate that it would take more than 10 times the load (4.0 lbs. vs. 0.37 lbs.) to cause damage on your treated sample vs. the untreated.

In other words, the weight of a debris particle required to crack a piece of glass that has been treated with Diamon Fusion® would need to be ten times heavier than the weight required to crack an untreated piece of glass.
