Directions for Use
Remove grease from the surface and make it clean.
Apply the adhesive to one surface and then fold the two Surfaces. Make it irradiated under the UV lamp with suitable Wave length and energy, from center to side, and ensure the UV light can irradiate the bonding surface thoroughly.
Do not press and scrub the bonding glass repeatedly. It is Recommended to use a fixed tool.
Cautions
T o prevent contamination of the unused product, don't return Any material to the original container.
Cure rate is dependent on lamp intensity, distance from light Source, depth of cure needed or bondline gap and light Transmittance of the substrate through which the radiation Must pass.
Cover the container immediately after each use.
Keep out reach of children.
The product contains acrylic ester, which may irritate skin And eyes. So it is recommended to use the product at a well Ventilated place.
In case of contact with eyes or skin, rinse with clean water Immediately; If symptom goes on, call aphysical attention.
