Abstract

UV curable adhesive was prepared by PUA,acrylate monomer,photoinitiator and fumed silica fillers in a certain proportion.The effects of different fumed silica fillers on viscosity and long-term viscosity stability in neutral and acid conditions were emphatically studied.The study found that Evonik AEROSIL VP NK2000 showed good stability under neutral conditions,and Evonik AEROSIL R805 showed good stability under acid conditions.In addition,it was found that three roller grinding was more conducive to viscosity stability than high-speed dispersion.

Key words
