Actnano
Actnano is a Specialty Polymers, Coatings & Surfaces company founded in 2012 and based in Cambridge, USA. It has raised $85M in total funding, most recently a Series C in 2024.
Founded in 2012 and based in the Boston area of Massachusetts, Actnano develops Advanced nanoGUARD, a gel-based hydrophobic nanocoating that protects printed circuit board assemblies from water, condensation, humidity, and salt. Unlike traditional conformal coatings, the coating can be applied across an entire board including connectors, antennas, LEDs, and high-heat components, providing 3-D protection. The company's coatings are used in ADAS and EV electronics across millions of production vehicles, and it has raised roughly $85M, including a $40M round led by Anthelion Capital in 2024.
A fluorine-free conformal coating already qualified into mass-market automotive electronics as PFAS regulation tightens.
