- Photo curable monomers/oligomers:Monofunctional acrylates
Ultraviolet absorption polymer is a product that gave polymer the ultraviolet absorption performance by using ultraviolet absorptivity monomer as one of the monomer.
Problems such as elution and precipitation of the ultraviolet absorber after curing do not occur compared with a general product that mixes the ultraviolet absorber with the polymer. Moreover, weather resistance of coating film and adhesion to the substrate can be improved. In addition, We can use various kinds of monomers on making polymers to achieve desired property. With the customers demand, we will challenge to synthesize the polymer.
It is polymer synthesized by the emulsion polymerization method using surfactant and water.
Polymer product polymerized in organic solvents such as the toluene, ethyl acetates, and methyl ethyl ketones.
It is a presentation of polymer that uses novel ultraviolet absorption monomer.
This polymer has the maximum absorption wavelength of ultraviolet rays in 350-370 nm. And, it is an ultraviolet absorption polymer with both ultraviolet absorption performance in the wide wavelength area of 300-400 nm and weather resistance.
It is examining it now.
