NOANOA61 Norland Optics UV Curing Optical Adhesive
Product Introduction:
Storage at room temperature without refrigeration but refrigeration
(1℃) is no harm. The product valid for more than half a year.
-- Standard adhesive for global optical industry. It is the most
suitable adhesive for optical bonding on glass surfaces, metals,
fiberglass and glass-filled plastics. Recommended for bonding
lenses, prisms, mirrors, and terminated or spliced fibers in
militery, aerospace and industrial optics.
Conforming to federal MIL-A-3920 standard for optical bonding
materials. It can withstand the temperature range of -150℃ to +125℃
after aging,. NOA61 has been widely used in domestic optical
component manufacturers. It is one of the standard adhesives in the
optical industry and the designated adhesive for many applications
worldwide. NOA61 is the flagship product of NOA series of glue and
is a kind of " balm" adhesive which is well known in the optical
industry.
It is a transparent, colorless liquid light polymer that can be
cured under UV light.It has many advantages when bonding optical
components provided that the bonding area can be illuminated by UV
light because it is one component and 100 percent solid. The use of
NOA61 lightsensitive adhesive eliminates the premixing, drying, or
heat curing operations typically required in other optical
adhesives and systems. The curing speed is extremely fast depending
on the thickness of the application and the energy received from
the applied UV light.
It has excellent light transmittance, low shrinkage and slight
elasticity compared with other optical bonding materials. These
characteristics are important to ensure that users produce high
quality optical components especially ensuring long-term features
in the face of changing environmental conditions.
It is UV curable and is very sensitive to ultraviolet light with a
wavelength of 350nm-380nm. The recommended energy for complete
curing is 3 joules/cm2. The area in contact with air will appear
non-viscous as long as it is sufficiently exposed to UV light
because this curing has no anaerobic reaction.
