The chemistry of paint: what's in the can, ongoing challenges and life in industry

Abstract

Paint is often considered a relatively simple and mundane material, when in fact there is very rich chemistry used to deliver the properties of paint that consumers demand. The key polymer component in most waterborne paint is a latex polymer, but polymers are also used as additives such as rheology modifiers, polymeric pigments and pigment dispersants. Combining these polymeric materials with pigments and other additives, the final paint formulation is a complex mixture. The dried paint film derived from these formulations has a structure and composition tuned to deliver specific properties such as gloss, opacity, surface texture etc.

 

This talk will provide an overview of the chemistry of paint and how certain features are delivered through the careful selection of materials. Some current problems in the coatings field will be outlined, along with a chemist’s view of life in industry.
