Glue is not curing reasons:
1. Inappropriate materials: UV glue requires bonding at least one side of the two sides of the material is light.
UV light intensity is not enough: If the amount of glue, need to choose high-power UV lamp, otherwise it will affect the curing time; if you choose natural light UV curing (UV is not visible), need to select daylight intensity, ultraviolet Of the light intensity will affect the natural curing speed.
3. Surface coating is not easy to cure: usually in the ultraviolet radiation, only through the light transmission material to make the glue curing. Direct irradiation of the glue is difficult to cure, so this glue is not suitable for surface drape use.
