---- UV/visible-light cure. NOA76 is recommended for bonding glass to plastic; typical uses are bonding glass to plastic or laminating polarizing film between glass. It is also sensitive to 400-450 nm visible light, which speeds cure of UV-absorbing materials. Withstands -80°C to +90°C
NOA76 is recommended for bonding glass to plastic. It bonds well to plastics such as acrylic, polycarbonate, and cellulose acetate butyrate. Typical uses are bonding glass to plastic, or laminating polarizing film between glass.
NOA76 cures under UV light at 315-400 nm and visible light at 400-450 nm. Peak absorption wavelengths are 325, 365, and 400 nm, with weak absorption at 410, 420, and 450 nm. Full cure requires 5 J/cm2 at 315~400 nm.
NOA76 cures under long-wave UV at 320-400 nm and visible light at 400-450 nm. Full cure requires 4 J/cm2 of long-wave UV, or 7 J/cm2 of visible light.
