Gloss Measurement

Gloss measurement is an important factor in quality control to guarantee a consistent and uniform gloss of any product. The visual perception is depending on the observer, illumination and viewing conditions as well as on material and product properties. In order to measure gloss objectively instrumental measurement is performed with a gloss meter. Dependent on the gloss level and the application different geometries and functions are needed. The following article reviews visual perception of gloss, measurement principle of a gloss meter, when to use which measurement geometry and gives practical hints for special applications and how to deal with limitations.

A comprehensive guide to Abrasion Resistance

We are confronted with abrasion resistance every day. Whether it is your shiny new bathroom floor that is beginning to fade or a scratch on the case of your new phone or car. Abrasion can ruin a day in a moment. So how do we test and improve our coatings on these appliances to mitigate the chance of this happening? In this article we will discuss what abrasion resistance is, how it relates to other physical properties, and what tools and methods are needed to measure it.

Guide for Reliable Gloss Data

Uniform and consistent gloss are an essential quality criterion for a variety of products. Therefore, gloss needs to be objectively measured. Only what can be objectively measured, can be controlled and can be optimized which is of importance in product development as well as in production control. Especially in case of multi-component products a uniform gloss is an expression of "high quality". Variations in gloss look like something is wrong and the end-user will perceive it as a defect. Therefore, gloss limits and tolerances are defined based on application and customer expectations.
