ThreeBond 3025G UV-curing resin for main sealing of liquid crystal |
ThreeBond 3025G is an ultraviolet-curing resin. In ultraviolet light with a wavelength of 200 to 400 nm, it cures in seconds; thus it contributes to the speed of manufacture. Also, because no heat is required for curing, it is not subject to distortion by heat. |
| · |
Cures in seconds in ultraviolet radiation. |
| · |
Requires no heat for curing. |
| · |
Can be applied from a dispenser. |
