Light weight and high design flexibility make transparent plastic sheets attractive for use as “organic glass” in many different applications, e.g., noise barriers, green houses, sport arenas, sky domes, solar panels or bus stop shelters. In addition, rigidity and impact resistance of acrylic (PMMA) and polycarbonate (PC) sheets were optimized expanding its usage for safety and architectural glazing as well as for automotive, aircraft, yacht or caravan applications. Depending on the application, the transparency requirements will be very different and need to be objectively controlled – often within very tight specification. More…

How many hours do you spend in your car? Most likely you will say “many”. Therefore, the interior design needs to reflect a comfortable ambience. Color and grain of the different components need to be harmonized. At the same time, low gloss is required to avoid any reflections in the windshield disturbing the driver. In order to achieve these goals, the variety of materials is the big challenge for every car manufacturer.
A world without color and shine, wouldn’t this be boring? Decorative coatings can be encountered every day and everywhere: on furniture, building facades, bridges and refrigerators. Even “White Goods” are no longer necessarily white, but exhibit fascinating color looks – from very elegant stainless steel to metallic effects on to colorful, glossy or textured surfaces.
Coatings are fascinating. Not much thicker than a human hair, they combine a variety of functions. Besides the requirement to look perfect under different lighting conditions, they are also expected to retain their good look over a long time and even when being exposed to harsh environments. More…
Did you ever walk into a glass door? The challenge is to make the product “invisible”, i.e. homogenous without any irregularities. Transparency is more than just the ability to transmit light. The perceived quality of a transparent product is dependent on how “good” we can see the objects behind it. It can appear crystal clear, hazy or unsharp. The human eye can perceive fine variations in sharpness as well as loss of contrast.
Our modern high-tech world is no longer imaginable without transparent products. We are so used to their “invisibility” that we only notice them if defects diminish their transparency, and consequently, their final usage. If due to varying quality of the packaging film the same chocolates appear different on the shelf, the nice holiday photos appear hazy on the smart phone, or the motorcycle helmet’s face shield easily gets scratched – then, all of this will affect our quality expectation and can even become a hazardous risk.

Objective Evaluation of Orange Peel with wave-scan
December 1, 2016 at 10:00 am EST
What influences our visual perception of appearance? How can the structure spectrum data be used to optimize appearance?
It is a daily challenge to achieve uniform surface appearance and at the same time meet the specifications of different auto OEM makers. Main influencing factors of our visual perception are the observation distance and the ratio of different structure sizes. As orange peel is highly influenced by material as well as processing parameters a good understanding of the measurement results will help you to achieve “Harmony”. Attend the webinar to learn more!
Join our Free BYK-Gardner Webinar:
Dec. 1st at 10:00am (EST)
In only 60 minutes you will learn what influences your visual perception and how to optimize the measurement results:
- How is orange peel and DOI of high gloss surfaces measured?
- How to interpret the structure spectrum?
- What material- and process parameters can influence Orange Peel and DOI?
- Customer specific auto OEM scales: R – CF – Tension – B-value?
- How low gloss can the surface be to get meaningful data with wave-scan?

Specialty glass manufacturers are developing ballistic resistance windshields for civilian and military vehicles. The windshields consist of various layers of polycarbonate materials that contain adhesives as well as protective layers of film. Various thicknesses are application dependent. Military vehicle protective shields require superior protection due to the increase in ballistic firepower in war zones.
Thickness variations have a direct correlation to the pass-through quality of available light, night or day. BYK-Gardner’s haze-gard i technology is used to measure total light transmittance as well as haze and clarity of various products. The goal is to produce a durable product by maintaining ballistic properties and improving visual attributes.

Gloss in Theory and in Practice
April 14, 2016, 10am Eastern Time
(Available in different time zones around the world here)
Whether matte or glossy – products with gloss variations are perceived as lower quality and can result in customer complaints. Gloss changes could be the result of a variety of process parameters as well as material properties. Objective and reliable measurement data with defined limits are the prerequisite for a stable production process. More…
Sample size and shape are important considerations when selecting a color or appearance instrument. Instruments typically have a fixed aperture size, and samples must cover the entire aperture in order to be measured accurately. More…
