ASTM D2851

This specification covers liquid optical adhesive for use in bonding glass to glass or other transparent adherends. The adhesive shall be in liquid form and free of solvent in order to avoid bubble formation in the adhesive layer. Each component shall be completely reactive. The adhesive may be heat-, catalyst-, or radiation-cured. Voltatility, color, viscosity, foreign particle content, refractive index, stability, light transmission, glass doublet preparation, environmental test, and bond strength tests shall be performed in accordance with the specified requirements.
