Application Of UV-1
This product is a highly effective anti-ultraviolet additive. It is
widely used in polyurethane, adhesive, foam and other materials.
Its excellent absorption properties enable it to effectively absorb
240~300nm ultraviolet light, and absorb almost all of it in the
300~330nm band. The UV effect is 1.1 to 1.4 times that of
benzophenone or benzotriazole. The amount of addition in
polyurethane is generally 0.2% to 1.0%, and the amount of sealant
added is 0.5% to 1.0%. It is recommended to mix with other UV
Packing & Storage
