Overview

A sealing material (single-component adhesive) for displays. The lineup includes a heat-curing type and combination UV + heat-curing type.

Features

Low moisture permeability

Possesses excellent moisture permeability and high reliability.

High adhesive strength

In addition to high adhesion to inorganic materials such as glass, the material also displays good adhesion to organic materials such as organic films.

Low liquid crystal pollution

Shows minimal elution of components into liquid crystal and good liquid crystal panel display properties.

Various manufacturing processes

Various manufacturing processes including screen printing and dispensers are supported.

Long pot life

Excellent viscosity stability at room temperature ensures a long working life.
