About Us

Q-Lab Corporation is a global provider of material durability testing products since 1956. We design and manufacture standard test substrates as well as weathering, light stability, and corrosion testers. In addition, contract test services which include accelerated laboratory testing are available at Q-Lab Florida, Q-Lab Arizona, and Q-Lab Deutschland. Outdoor exposure testing for weathering, lightfastness and corrosion are available at Q-Lab Florida and Q-Lab Arizona.

Our weathering products and services are used by material scientists and technicians in numerous industries including: additives and colorants, adhesive and sealants, automotive, building materials (such as roofing and siding), fabrics/textiles, food and beverages, graphic arts/inks, paints and coatings, pharmaceuticals and cosmetics, plastics and packaging, and renewable energy (such as solar).

Our modern corporate headquarters, R&D, and manufacturing facilities are located in Westlake, a beautiful suburb of Cleveland, Ohio USA. Q-Lab sales and distribution facilities are located in Manchester, England, Saarbrucken, Germany, and Shanghai, China. Q-Lab's A2LA accredited laboratory and outdoor testing facilities are located in Homestead, Florida and Buckeye, Arizona. We've also just opened a new accelerated testing lab at our Saarbrücken, Germany location.

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".

• 

  1956 – Q-Panel Co. is founded in Cleveland, USA to fill a need for standard test panels for paint research. The company name is eventually changed to Q-Lab in 2006.

• 

  1960 – Q-Lab's first new factory is built in Cleveland, Ohio.

• 

  1965 – QCT “Cleveland Condensation Tester” introduced by Q-Lab. This precursor to the QUV provides condensation only, but no UV.

• 

  1970 – QUV Accelerated Weathering Tester introduced. This revolutionary design by Q-Lab combines condensation and fluorescent UV. Today, the distinctive shape is recognized throughout the world.

• 

  1977 – Publication of the first of many ASTM and international specifications that reference the QUV tester.

• 

  1980 – European sales office and warehouse opened in the United Kingdom, near Manchester.

• 

  1981 – Q-Lab moves to a new, larger factory in Westlake, Ohio.

• 

  1983 – QUV becomes world’s most widely used weathering tester, based on number of units in use.

• 

  1984 – UVB-313 lamp introduced. This Q-Lab design is the first lamp specifically designed for a fluorescent weathering testers.

• 

  1987 – UVA-340 lamp introduced. This Q-Lab innovation is still the best available simulation of short wavelength sunlight UV.

• 

  1989 – QUV Spray Option introduced to supplement the QUV tester’s condensation system. Spray produces mechanical erosion on wood coatings, and thermal shock on plastics.

• 

  1997 – Q-TRAC natural sunlight concentrator testing is offered at Q-Lab Arizona for accelerated outdoor testing.

• 

  1998 – Q-Lab introduces the Q-SUN Xe-3 flat-array lightfastness and weathering tester, a breakthrough in price/performance ratio for xenon arc testers.

• 

  1998 – The Q-SUN Xe-1 is launched. It provides the same state-of-the-art xenon technology as the Xe-3 tester, but in a compact, table-top model.
