Washable thermographic paint for special applications

HEWP-LT

Washable thermographic spray paint with high emissivity for special applications at room temperatures. The paint can be easily removed with water without the use of harsh mechanical methods or chemicals. Ideal for the measurement where permanent use of paint is not possible. The precisely defined dependence of the emissivity on the wavelength and viewing angle of the infrared camera enables to achieve very precise results of thermographic measurements.

Instructions for use

  1. Abrade the surface, clean it, dry it and get rid of grease. Cover other areas where spraying is not to be applied.
  2. Shake the container for two minutes and make a test spray.
  3. Spray slowly over the material from a distance of 25-30 cm. Apply two thin layers.
  4. Spray at temperatures 15-25 °C. Paint hardening occurs after two hours.
  5. After use, turn the container upside down and clean the valve by pressing for a few seconds.
