Glass surfaces are coated for many reasons: for safety, for convenience or for better stability. To ensure that the coating is uniform and durable, both the glass surface and the coating must be prepared for the coating process. Our measuring instruments assist glass-processing companies in the design and quality assurance of the coating process.

Glass surfaces must be dry and free from grease before coating. The measurements can be used to check that the cleaning is thorough and uniform, as a homogenous glass surface has the same water everywhere. Our mobile measuring equipment enables glass surfaces of any size to be tested non-destructively.

The surface enegry of glass coating should be such that interactions between the phases ensure good wetting and adhesion. For this purpose, the glass can be accurately characterized using measuring instrument, and the coating using a tensiometer. Good wetting can be expected if the surface tension of the coating is less than the surface free energy of the glass.

The ratio of polar and non-polar (dispersive) interaction fractions of the surface tension of the two phases is decisive for the adhesion of the coating. The more similar the pro-rata polarities, the better the coating adheres.
