Products' features and typical usage

367

Suitable for widely bonding material, have a high adhesion to all kinds of circuit board basic materials, plastic , glass and metal materials; fast surface curing(surface dried), moisture-proof, resistant to high temperature, high humidity, ultraviolet, insulation, remain stable even though under the harsh environment.; Can choose fluorescence effect formula,

It shows as blue color when illuminating the glue with low power ultraviolet light in the dark room after curing, it can be tested. Typical applications in the surface coating of PCB, solar panels materials, etc.

368

Have an excellent adhesion to PET and other materials with low surface energy requirement,, good flexibility, bending resistance; fast curing of surface side(surface dried), high transmittance, moisture-proof, insulation, uvioresistant, resistant to high temperature and high humidity and; typically applications in surface coating of plastic film circuit board.

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.
