Tempilaq Temperature Indicating Paint is used by top teams to document temperatures that are difficult or impossible to measure during actual use.
Tempilaq paint has a calibrated melting point that leaves an instant indication when a specific temperature has been reached. On race cars, it is most useful on brake discs and pads but can also be used on other components such as exhaust systems. It is also handy to have in the shop during fabrication and welding.
To use Tempilaq, apply a thin coating to the test specimen. The paint dries almost instantly with a dull matte finish. If the rated temperature is exceeded during use, the coating will become glossy, thus leaving a permanent indication that the temperature was reached. 2 oz brush top bottle.
Note: Because of the high solids content, the pigment settles out of the paint during storage. If this happens, simply re-mix the paint, adding a little Tempilaq Thinner if necessary.
