UV Resin gets sticky on acrylics

Hello! I have been using UV resin to cast molds of earings i’m making, the resin comes out fine and not sticky, but when i paint those earings in acrylic paints and put a thin layer of the same uv resin over it to seal it, it’s sticky as hell!! I exepted a clean finish and instead it catches cat hair and dirt! Any advices? Thanks!
