IN311680: An improved binary pressure sensitive paint coating
Abstract
The invention discloses an improved binary pressure sensitive paint coating having improved adhesion and enhanced shelf-life, suitable for wind tunnel studies in both transonic and supersonic flows, and also suitable for application over larger surface areas on the model. The improved adhesion and enhanced shelf-life of the pressure sensitive paint coating has been achieved by replacing the epoxy screen layer with a new silicone-titanium dioxide screen layer cured at room temperature to get consistent paint properties. Pressure sensitive coating of present invention is also suitable for wind tunnel studies in both transonic and supersonic flows applications. The improved binary pressure sensitive paint of invention is suitable for application over larger surface areas on the model, by mixing proportionally larger quantities of PSP ingredients and by removing the excess dichloromethane in the resulting PSP formulation before mixing with other remaining ingredients.
