5 ML Liquid Optical Adhesive Glue
Colorless and transparent, light transmittance of 98% or more, good adhesion strength, can be cured at room temperature or moderate temperature conditions. And at the same time with low cure shrinkage, resistance to yellowing. Compared with the traditional OCA adhesive tape, LOCA has particular advantages in some fields of application, can solve the limitation of OCA tape facing. Characteristics of liquid optical adhesive LOCA
1, High light transmittance (full penetration rate of >99%)
2, High bonding strength and easily folded gum rework unqualified adhesive.
3, High adhesion, high weather resistance, water resistance, high temperature resistant, anti ultraviolet, long time do not use products yellowing, peeling and the deterioration of the problem.
The transparent substrate
free is tropic adhesive can ensure accurate
color and the brightness
of the display, and provide bonding durability, high strength
