Electronic package lamination with silicone gel

Also known as liquid optical silicone adhesive, water-based adhesive, or LOCA, it belongs to the category of optical adhesives and is a specialized adhesive primarily used for bonding transparent optical components. Its applications include display assembly, lens assembly, resistive touchscreens, capacitive touchscreens, panel bonding, and the adhesion of other related electronic and optical materials.

BTY-5270AB

A two-component, UV-curable liquid silicone rubber that forms a gel-like consistency upon curing. The cured formulation exhibits excellent resistance to yellowing, superior UV‑aging stability, and a very low shrinkage rate. With a jelly‑like gel texture after cure, it offers exceptionally high light transmittance, outstanding high‑temperature and UV‑induced yellowing resistance, and minimal volumetric shrinkage, while also providing strong adhesion to a wide range of substrates.
