Product information "NOA 76 Optical Adhesive 10g syringe"
Viscosity at 25°C: 3500-5500 cps, Refractive Index: 1.51
Norland Optical Adhesive 76 (NOA 76 10g syringe), also known as NOA 76A, is an optically clear, liquid adhesive that will cure when exposed to long wavelength ultraviolet light. It is also sensitive to visible light between 400 - 450 nanometers which will assist in producing faster cures when curing through UV absorbing materials. This one part, moderate viscosity adhesive is 100% solids and offers advantages in optical bonding applications. The use of NOA 76 eliminates premixing, drying or heat curing operations common to other adhesive systems.
NOA 76 is recommended for bonding glass to plastic. The adhesive has best adhesion with plastics such as acrylic, polycarbonate and cellulose acetate butyrate with typical applications being glass to plastic bonding or laminating polarized film between glass.
