Complete and accredited in-house capabilities for testing are a key part to providing quality products. Kay performs in-process product testing and process controls for 100% quality documentation. We test all materials used in our products including films, inks and adhesives. Over the years, Kay has invested in state-of-the-art equipment and recruiting the best qualified people to utilize it.  As part of this extensive testing, more than 40,000 weathering panels containing over 275,000 samples have been evaluated over the past 50 years. In addition to sending panels to Florida and Arizona for a period of 5 years, Kay uses in-house state-of-the-art equipment to fully test every product before it is sent to production.
