Coatings, Inks, Paints and Adhesives

Coatings
Paints mainly consists of Polymer, Pigments, Carrier, solvents and additives. They perform according to physical and chemical interactions within this mixture. Since formulation and applications of Paints & Coatings are limited by the regulatory bodies as these may cause air and water pollution by releasing toxic or hazardous materials, there is a great need of keeping track of their quality. SRI assists the Industry by ensuring the quality of the Paints & Inks through its quality control.
