UV Resin
UV Resin, also known as photosensitive resin, is a kind of light irradiation, can be in a relatively short period of time to rapidly undergo physical and chemical changes, and then crosslinking and curing of the oligomer.
UV resin is a low relative molecular mass photosensitive resin, with UV reactive groups, such as unsaturated double bonds or epoxy groups.
UV resin is the base resin of UV coatings, which is compounded with photoinitiators, active diluents and various additives to form UV coatings.
Shadowless Adhesive
Shadowless Adhesive (uv adhesive), also known as photosensitive adhesive, ultraviolet curing adhesive, shadowless adhesive is a must through ultraviolet light irradiation in order to curing a class of adhesive, which can be used as a bonding agent, but also as paints, coatings, inks and other adhesive materials used.UV is an abbreviation of Ultraviolet Rays, that is, ultraviolet rays. Ultraviolet (UV) is invisible to the naked eye, is a section of electromagnetic radiation other than visible light, wavelengths in the range of 110 ~ 400nm. Shadowless adhesive curing principle is UV curing materials in the photoinitiator (or photosensitizer) in the ultraviolet irradiation of ultraviolet light absorption of ultraviolet light to produce reactive radicals or cations, triggering the monomer polymerization, cross-linking chemical reaction, so that the adhesive in a few seconds from the liquid state into a solid state.
