Product Introduction
Product type: UV absorber
Chemical structure: N-(ethoxycarbonylphenyl)-N'-methyl-N'-phenylformamidine
CAS number: 924-42-5; molecular formula: C4H7O2N; molecular weight: 101.1 g/mol
Product Features
Seeyon®UV1 is a liquid formamidine UV absorber, which can effectively absorb ultraviolet light with a wavelength of 240-350 nm. Its maximum absorption peak is 308 nm and it can almost completely absorb in the 300-330 nm band, while polyurethane is susceptible to degradation by radiation in this band. Seeyon®UV1 has excellent photostability to polyurethane products, such as soft and hard foams, elastomers, leather, fabric coatings, adhesives and coatings. It can inhibit photooxidative degradation, prevent product aging, enhance the color stability of products and prolong their service life. It has a remarkable synergistic effect when used together with antioxidants and light stabilizers.
