Due to the photoactive nature of ePaint SN-1, additional coats around the waterline are strongly recommended to extend service life.

SN-1 is thermo-plastic by nature and hot temperatures above 90oF can soften SN-1 slightly, particularly on aluminum boats in full sun, which can cause paint to dig into pads and straps. If SN-1 is to be launched in hot climates, consider launching boat in the morning before full sun and temperatures climb. Place plastic sheeting between pads and straps before lifting. The thermo-plastic nature of SN-1 has no effect on antifouling performance and paint will immediately harden when placed into service of cooler waters.


ePaint SN-1 coating technology was developed, uses materials from, and is proudly manufactured in the USA. Please contact at for more information on ePaint SN-1 or other ePaint products.
