Paint Testing Lab

Paint is more than just a coating for surfaces—it is a protective barrier against environmental factors, a safety layer in industrial applications, and often the first impression of a finished product. Ensuring that paints meet durability, safety, and performance standards is therefore essential across industries like construction, automotive, engineering, and infrastructure.

At Krishna Metallurgical Laboratories (KML), we specialize in comprehensive paint testing services designed to validate quality, performance, and compliance with national standards. As a NABL-accredited paint testing lab, we combine advanced infrastructure with strict adherence to Indian Standards (IS), giving industries confidence that their paints are reliable, safe, and built to last. We also offer extensive corrosion testing (like salt spray, cyclic corrosion, thermal shock), abrasion testing including Taber/Akron abrasion and chip resistance, and environmental testing such as UV resistance, weathering, humidity, rain, and heat ageing to make sure coatings perform under harsh real-world conditions.

Why Paint Testing Matters

Paints face a range of challenges in real-world applications. They are exposed to heat, humidity, chemicals, oils, weathering, and constant wear and tear. A coating that performs poorly can lead to surface degradation, costly maintenance, and safety hazards. Proper testing ensures that paint formulations are consistent, environmentally safe, and capable of withstanding the conditions they are designed for.

KML’s suite of tests addresses these challenges directly by covering physical properties, chemical stability, and performance behavior under simulated real-world conditions.
