About the Staff

Testing and evaluation is one of the most important part of materials utilization in various industrial applications. Material specification, material characterization, material behavior and its performance evaluation is the first step in any utility application. It is also important to qualify materials being supplied by various vendors. Material analysis and its certification is another important aspect, required frequently by industry. Paint testing & its certification has become an important industrial requirement.
It is a responsible job which requires correct knowledge of the subject, knowledge of various paint standards and their right use in evaluation of paint properties.
KHANNA PAINT TESTING LABORATORY (OPC) PVT. LTD. (KPTL) is the new name given to Surface Engineering & Coating Consultant as per the requirement of NABL as registered entity. It was initiated by Qualified academician & experienced personnel’s in the field of Corrosion & Coatings Science Prof. A. S. Khanna is having 27 years of experience in a prestigious education institute, Indian Institute of Technology Bombay, as well as working in several International Laboratories. After retirement from IIT Bombay, he decided to extend his services to help industry in creating a state of the art testing and evaluation facilities with consultancy and advisory component also. Now Prof. A. S. Khanna is The Director of this company.
The testing lab is located at Kailash Industrial Complex, Vikroli (West). It has all basic facilities of paint testing, paint performance evaluation, mechanical properties of coatings, weathering and chemical properties evaluation at reasonable cost.
I am looking forward to your support and cooperation to make this dream come true.
