Norland NOA61 Optical Adhesive 365nm UV Cure

These are authentic Norland NOA61 optical adhesive in 1cc or 3cc bottles. I recommend a 365-395nm UV light source (the higher the wattage the faster it will cure) or just leave it in the sun the UV rays will cure the NOA61 (3w UV light takes 5-15 seconds to cure). Please be aware and keep this out of sun or any UV light.  Norland Optical Adhesive 61 ("NOA 61") 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 light. The use of NOA 61 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 61 meets Federal Specification MIL-A-3920 for optical adhesives and is approved for use on all government contracts specifying such adhesives. The adhesive is designed
