Product information "NOA 75 Optical Adhesive 10g syringe"
Refractive Index 1.52; 80-95 cpsViscosity at 25°C
Norland Optical Adhesive 75 (10g syringe) is a clear, colorless, liquid photopolymer that will cure when exposed to ultraviolet light. Since it is a one part system and 100% solids, it offers many advantages in bonding where the adhesive can be exposed to UV or visible light. The use of NOA 75 eliminates premixing, drying or heat curing operations common to other adhesive systems. Curing time is remarkably fast, and is dependent upon the thickness applied and the amount of ultraviolet light energy available.
NOA 75 is designed to give the best possible optical bond when using plastic to plastic or plastic to glass substrates. NOA 75 has excellent adhesion to cellulose acetate butyrate (CAB) and glass and good adhesion to CR-39, polarizedfilm, nylon, polyester film, polycarbonate and acrylics.
