UV curing pressure-sensitive adhesive includes three options
(1)UV curing acrylic pressure sensitive adhesive,
(2) UV curing polyurethane-acrylic pressure-sensitive adhesive,
(3) UV curing SIS series hot melt adhesive.
The products of these three schemes all have the characteristics of 100% solid content, excellent heat resistance, aging resistance and fast curing speed. The reaction principle of UV curing acrylic pressure-sensitive adhesive is to combine the photoinitiator on the main chain of the polymer, so that even if the photoinitiator does not participate in the complete reaction, it also exists on the main chain of the polymer, will not free out, so it will not produce odor.
UV curing polyurethane-acrylic pressure-sensitive adhesive is made of polyurethane and polyol by halogenation and other chemical reactions, fiber, in order to achieve the performance of adjustable stripping force, has been widely used in the field of medicine. Although UV curing polyurethane-acrylic pressure-sensitive adhesive is not fully applied in the label field at present, it will be a development direction in the future.
The properties of UV curing SIS series hot melt adhesives, such as viscosity and peeling force, cannot be achieved by ordinary adhesives.
Overall, UV light curing technology is used to replace solvent-based pressure-sensitive adhesive pressure sensitive adhesive field is an inevitable trend of development, only in the practical application of all aspects of the performance will be constantly summarize and improve, with the passage of time, UV light curing pressure sensitive adhesive of related products, UV light curing technology will become the major production process in the field are used by people.
