Coating technology research. Researcher adjusting equipment during work on surface coatings technology. This includes work on fluids, gels and powders, which can be applied to a surface using a range of techniques ranging from electrostatic coating to spray coating. Photographed at Hi-Tech Spray, a company based in Maidstone, Kent, UK. It specialises in designing and developing solutions for surface coating applications. The company was established in 1987. Clients include airplane manufacturers, film studios, and oil industry companies. One such project is the Hi-Tec Hydra- Cat, which mixes a liquid rubber material into the right proportions to be sprayed on oil pipe connections. The rubber acts to reduce damage to the pipes caused by wave action.
