LabIR^® Paint

Thermographic paint for high temperature

HERP-HT-MWIR-BK-11

Special thermographic spray paint with high emissivity and high mechanical resistance for long-term applications to high temperature up to 1 000 °C. Precisely defined physical properties and emissivity dependence on the wavelength, viewing angle of an infrared camera and temperature of the measured surface allow accurate results of the non-contact temperature measurement.

Price: 20.57 EUR (17.00 EUR without VAT)

Instructions for use

The surface to be sprayed must be clean, free of rust, grease and dirt. Cover the areas that you do not want to spray.
Shake well (three minutes) and test before use.
Spray evenly, using slow movements from a distance of 30-50 cm. Apply four thin layers, wait for a while and then apply four thin layers again.
Processing temperature: 15 - 25° C; hardened in 2 hours.
After use, turn the bottle upside down and clean the valve by pressing it for several seconds.
