Liquid optical adhesive LOCA

Colorless and transparent, light transmittance of 98% or more,good adhesion strength, can be cured at room temperature ormoderate temperature conditions. And at the same time with low cureshrinkage, resistance to yellowing. Compared with the traditionalOCA adhesive tape, LOCA has particular advantages in some fields ofapplication, 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 reworkunqualified adhesive.

3, High adhesion, high weather resistance, water resistance,high temperature resistant, anti ultraviolet, long time do not useproducts yellowing, peeling and the deterioration of theproblem.

 

The scope of application of liquid optical adhesive LOCA

Liquid optical adhesive LOCA can be used as adhesive oftransparent optical materials, such as ITO film, PMMA, PC, PET,glass, electronic paper display, projection screen assembly,assembly, the lens assembly, resistive touch screen G+F+F, F+Fbonding, capacitive touch screen panel, ICON, and other relatedelectronic and optical materials. The transparent substrate free istropic adhesive can ensure accurate color and the brightness of thedisplay, and provide bonding durability, high strength
