Outdoor exposure racks and accelerated chambers are the two main methods for testing materials for weathering durability. In the fast paced current world, time constraints have determined that outdoor weathering exposures take too long to provide the...

In the 1980s, damage to automotive coatings from acid rain became a problem. Both dealerships and buyers complained about the ring type or “water spot” etches that were caused by acid catalyzed hydrolysis in areas where acid rain occurred and tempera...

How can you know whether an ink will remain fade resistant under the variety of lighting conditions that it may encounter during its service life? What is the cost of product failure? What is the price/performance trade-off between affordability and ...

Artificial weathering plays an important role in the development of improved coating systems by providing a means of obtaining performance assessments in much shorter time than it is possible using natural weathering. However, there exists at present...

The popularity of personal computers and digital cameras has ushered in an exploding new market of digital images printed from consumer printers. There is an endless combination of ink jet inks and commercial photo papers currently available in the m...

Why should you test products for lightfastness and weatherability? Ian Johnston, director of research and development for Inkware LLC sums it up in a sentence: “It helps us to sleep better at night.”Download File

A variety of accelerated weathering techniques have been developed and utilized over the last 40 years of coatings research in an effort to predict "real" weatherability of all coating systems in a short period of time. 1 • 4 Accurate predictive capa...

The performance and durability of 11 industrial coating systems were studied for two and a half years at five weathering sites in the industrial belt of Shuaiba Area, KU'wait, in the Arabian Gulf. Coating performance was related to prevailing industr...

On earth, our major source of radiant energy is the sun. It supplies warmth (heat or infrared radiation), light radiation (both visible light and ultraviolet light), and a wide range of energy of other types (e.g., X-rays, gamma rays, and cosmic rays...

Short wave UV light is responsible for much of the damage to sealants exposed outdoors. Moisture also causes damage, and there often is a synergistic effect between UV and moisture. Experience has shown that materials resistant to UV alone or to mois...
