basic introduction

ZRLK testing is aimed at thermal functional coatings, architectural energy-saving coatings, chemical functional coatings, and electromagnetic functional coatings. It provides third-party CMA and CNAS authoritative testing reports based on various coating test table standards and various subdivided performance indicators of functional coatings.
