Infrared Coats

Infrared Shielding Coats *Patent Pending

Not all colored polycarbonates can block infrared. RENIAS developed IR absorbing nanoparticles and primer particle dispersion technology allowing for IR blocking with superior transmittance of visible light.


Light Transmittance by Polycarbonate Color

Light Transmittance Comparison between RENIAS and other company's IR Coats

We estimate a drop of nearly 5°C

As you can see in the chart above, our REMR-SCIR allows considerably more visible light and considerably less IR light through compared to our competitors.

Surface Temperature Test

We verified an over 10°C drop in surface temperature under mid-summer conditions.
