PURPOSE: To obtain the subject sealing material excellent in workability and adaptability to an automatic machine before curing and having high flexibility at both ordinary temperature and low temperature after curing by using a photo-setting monomer or oligomer and an organic fine powder of a specified low Tg as the constituents.
CONSTITUTION: This sealing material contains a photo-setting monomer and/or oligomer (e.g. diethylene glycol acrylate or urethane acrylate resin) and an organic fine powder (e.g. a fine urethane powder or a fine ethylene/vinyl acetate copolymer powder) with a Tg of -10°C or lower. This sealing material has moderate viscosity and thixotropic properties and is excellent in workability and adaptability to an automatic machine before curing while it has high flexibility at both ordinary temperature and low temperature after curing.
