OCA Optically Clear Adhesive
OCA optical adhesive is one of the important raw materials for touch screens. It is a double-sided adhesive tape made of optical acrylic adhesive without a substrate, with a release film on each of the upper and lower layers. It is the best adhesive for touch screens.
OCA optical adhesive is divided into resistive OCA and capacitive OCA. Resistive optical adhesive generally has two types: 50um and 25um. Capacitive optical adhesive has thicknesses of 100um, 175um, 200um, and 250um.
Our OCA advantages: high clarity, high transparency (full light transmittance >99%), high adhesion, high weather resistance, water resistance, high temperature resistance, UV resistance, providing uniform spacing, and no yellowing (yellowing), peeling, and deterioration problems after prolonged use.
