LabIR^® Paint

Washable thermographic paint for special applications

HEWP-LT-MWIR-BK-11

Washable thermographic spray paint with high emissivity for special applications at room temperature. The paint can be easily removed with water without the use of aggressive mechanical methods or chemical agents. Ideal for measurement of places where you can´t use a permanent paint. Guaranteed physical properties and the dependence of emissivity on the wavelength and camera viewing angle allow you to achieve highly precise results of non-contact temperature measurement.

Warning

Extremely flammable aerosol. Product container is under pressure. When it is heated, it can explode. It causes serious eye irritation. It may cause drowsiness and dizziness. Repeated exposure may cause skin dryness or cracking. If medical help is needed, keep handy product container or label. Keep out of the reach of children. Before using, be sure to read the information on the label. Do not breathe aerosol. Keep away from heat/sparks/open flames/hot surfaces. No smoking. Pressure container: Do not pierce or burn even after use. Do not spray on an open flame or other ignition source. Protect from sunlight. Avoid temperatures exceeding 50 °C.

Recycling

Contents / Dispose of container in accordance with local/regional/national/ international regulations.

Instructions for use

Abrade the surface, clean it, dry it and get rid of grease. Cover other areas where spraying is not to be applied.
Spray from a distance of 25-30 cm. Apply two thin layers.
Between the applications of individual layers, do not wait for curing.
Spray at temperatures 15-25°C. Paint hardening occurs after two hours.
After use, turn the container upside down and clean the valve by pressing for a few seconds.
