Instructions for Use
The Surface to be bonded should be clean and dry. Spread the adhesive onto the surface to be bonded.
Exposed to UV light measured @ 365nm, make sure the material to be bonded is light transmittable.
Curing rate is dependent on UV light intensity, distance form light source, and curing time. Close the lid as soon as finish the operation. Spread the glue with black container, keep away from daylight, UV light and artificial lighting.
Notice
Keep far away from children.
In case of contact with skin, rinse with soap water immediately. If contact with eyes, rinse with a plenty of clean water immediately and go to the hospital for an examination. For further information, please refer to MSDS.
