“When Quality Matters Most”

Protech has been in the materials testing industry focusing on coating evaluations and analysis since 1980. Through years working in the coatings industry, it was apparent that there were significant variations among laboratories in evaluations of coatings, primarily due to polishing anomalies that resulted in inconsistent evaluations of the material structures. With the many variations in coating structures from different laboratories, there was a clear need for a laboratory that specialized in coatings, where two or more materials are contained in one sample. Such a system requires great knowledge of all materials contained within the specimen to ensure correct polishing techniques are employed to provide an accurate representation of the coating structures. The team at Protech posses the expertise and knowledge required to meet all of your needs and stands ready to support our customers in any way possible. When quality matters most, contact Protech Lab Corp for all of your coating requirements.
