Notes

1. Storage under 8℃－25℃, in the dark, sealing, ventilation, cool conditions, and far away from children.

2. Keep air ventilation when using, and take the safe protection measures, such as don't use your skin to touch the resin directly or longly.

Remarks

1.) Viscosity standard： Tested under 25℃±0.5, by using the container with diameter 6-7cm, and height 10cm.

2.) The setting time of above items were tested under the condition of glass bond glass  with 40w and light intensity is under 7.5mW/cm2.                                                                                                                                           3.) Above tensile & shear strength data tested when glass bond glass, glass bond crystal.

4.) Other test parameters are tested on the basis of the national testing.
