UV Absorbent 1.Anti UV, keep the coating surface new; 2.Use in the polymer of PC, PS, PVC; 3.Paint and coating
Characteristics and technology index:Color: yellowish powderThe max. wavelength: 308mmMelting point: 55 - 59°CVolatility: 10%Heat weightlessness temperature: 204°C (N2, 10°C/min)Solvent: can solve in the organic solvent acetone, dichlor methane, acetic acid,toluene, dimethylbenzene and alcohol, and cannot solve in waterUV-2 is a new structure UV absorbent, which can absorb the mid and low wavelengthof the UV spectrum (UV-B). With the comparison of the traditional hydroxyl insteadof the diphenyl ketone, UV-2 shows the higher absorption rate, and farthestprovides protection to the photodegradation of the polymer. Meanwhile, it cannotmake the polymer bepaint that is the traditional UV absorption beyond achieving.Aside, matching with the hindered amines light stabilized, it can show excellentcooperation effect.Application:It can be widely used in the polymer of PC, PS, PVC, and can be used solely or togetherwith the light stabilized. With the colophony making into concentrate, cansolve 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 UVabsorption effect is superior to the traditional light stabilized Tinuvin900 andCyasorb1164. In the impact polysterol, UV-2 and Tinuvin123 together shows theexcellent 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 referencedosage is based on the sufficient text, but each user must be based on your situationto adjust the dosage, so this dosage possesses no law meaning)Package:
25kg/case, stored in a cool and dry place
