UV-2 is a new structure UV absorbent, which can absorb the mid and low wavelength
of the UV spectrum (UV-B). With the comparison of the traditional hydroxyl instead
of the diphenyl ketone, UV-2 shows the higher absorption rate, and farthest
provides protection to the photodegradation of the polymer. Meanwhile, it cannot
make the polymer bepaint that is the traditional UV absorption beyond achieving.
Aside, matching with the hindered amines light stabilized, it can show excellent
cooperation effect.

Application:
It can be widely used in the polymer of PC, PS, PVC, and can be used solely or together
with the light stabilized. With the colophony making into concentrate, can
solve in the solvent and print on the surface of products.

Dosage:
The recommend dosage is 0.3%. With 0.3% UV-2 into the 1.2mm PVC material, the UV
absorption effect is superior to the traditional light stabilized Tinuvin900 and
Cyasorb1164. In the impact polysterol, UV-2 and Tinuvin123 together shows the
excellent cooperation effect. UV-2 can be widely used in the polyester lacquer,
wooden lacquer, car lacquer, gel agent and so on.

The reference dosage: generally, commend dosage is 0.05% to 0.3% (this reference
dosage is based on the sufficient text, but each user must be based on your situation
to adjust the dosage, so this dosage possesses no law meaning)
