A pressure sensitive paint is coated onto the surface over which a pressure distribution is to be measured, such as in a wind-tunnel test of an aerodynamic body. A pressure sensitive paint is a mixture of a photoluminescent-compatible, oxygen-permeable binder that is a mixture of silanol-terminated polydimethylsiloxane and methyltriacetoxysilane, and a photoluminescent active agent such as tris(4,7-diphenyl-1,10-phenanthroline) ruthenium(II) chloride pentahydrate. The binder and active agent are placed into an appropriate amount of a solvent for the binder and the active agent, such as dichloromethane, and applied to a surface. In testing of the surface such as wind tunnel testing, the active agent quantitatively luminesces responsive to the local external pressure at the surface.

A pressure sensitive paint, comprising in combination a mixture of a photoluminescent-compatible binder comprising a binder mixture of silanol-terminated polydimethylsiloxane and methyltriacetoxysilane, wherein the silanol-terminated polydimethylsiloxane is present in an amount of about 97 parts by weight of the binder, and the methyltriacetoxysilane is present in an amount of about 3 parts by weight of the binder, and a photoluminescent active agent, where the binder is present in an amount of from about 99.5 to about 99.9 percent by weight of the mixture of binder and active agent, and the active agent is present in an amount of from about 0.5 to about 0.1 percent by weight of the mixture of binder and active agent, whereby, when the paint is applied to a surface, oxygen in the air permeates through the binder to partially quench a photoluminescent reaction of the active agent.
