The Q-Lab Name & History

George Grossman, Founder

A young pilot in the US Air Corps returned to civilian life after serving his country. His name was George Grossman, and he began a new career selling supplies and equipment to paint labs in the Cleveland, Ohio area. Wherever he went, George made it a practice to ask his customers, "What do you need that you can't get from your current suppliers?" Many customers told George that they needed a consistent, reproducible test surface. They wanted to make sure that if a coating failed during testing, it was because of a bad paint and not because of a contaminated substrate.

George founded Q-Panel Lab Products in 1956 to fulfill this industry need. When designing the first test panels, George was looking for a way to place a logo on his product that would not be obscured when the lab technicians sprayed the panels with paint. He decided that a "Q" shaped hole would do the trick. Plus, it would represent the quality and quick delivery that George wanted for his panels.

50 years later, Q-Lab Corporation has established the global standard for affordable, reliable, and easy to use weathering, lightfastness, and corrosion test equipment and test services. This philosophy and customer-first approach has made us "the most trusted name in weathering".
