This study investigated the impact of various reactive diluents on viscosity of uncured mixture at 50 °C over a 12-week period. This criterion is important to predict the shelf life of uncured composition. Studied mono-functional acrylate monomers were: hydroxypropyl methacrylate (HPMA), hydroxyethyl methacrylate (HEMA), tetrahydrofurfuryl acrylate (THFA), isobornyl methacrylate (IBOMA), isobornyl acrylate (IBOA), 2-(2-Ethoxyethoxy)ethyl acrylate (EOEOEA), acryloyl morpholine (ACMO), glacial methacrylic acid (GMAA) and phosphate acrylate monomer (PAM); and various solvents: isopropanol(IP) ethyl acetate (EA), butyl acetate (BA). There was found the difference of effect on the systems viscosity in time between the mono-functional monomers and solvents. HPMA and IPA showed the most stable viscosity values in time.
