ThreeBond 3036 UV-curing resin

ThreeBond 3036 is a one-part, nonsolvent ultraviolet-curing resin, in which acrylate is a major component. It cures quickly in ultraviolet radiation at a wavelength of 200 to 400 nm, and thus speeds manufacture. Its curing contraction and its linear expansion coefficient are lower than those of conventional acrylate-based ultraviolet-curing resins. Also it is thixotropic, and even a relatively thick layer cures. The product is suitable for plastics, glasses, and metals.

·	Under ultraviolet irradiation, cures in a few seconds to several tens of seconds.
·	Has a low linear expansion coefficient.
·	Has a smaller curing contraction ratio than the conventional acrylate-based ultraviolet-curing resins.
·	Is thixotropic.
·	Cures quickly even in a thick layer.

·	Bonding of optical components such as optical pickups
·	Bonding of plastics
