Abstract

Described is a method and an apparatus for producing cured coating films on a substrate surface. Specifically, a portable spraygun may be used to initiate radiation cure without the operative having to be protected from radiation. The spraygun comprises a supply channel for a radiation-curable coating composition, a needle, a reserve for the radiation-curable coating composition, and, optionally, a supply channel for a gas.
