3.what is UV 329 used for

3.1UV329 has a very effective light stabilizing effect, prevents yellowing and degradation of polymer. Can be used for example, polyolefin, polystyrene PVC, unsaturated polyester, acrylic resin and ABS resin.

3.2 UV-329 can be used alone, or with other stabilizers used in conjunction.

3.3 UV-329 and hindered amine light stabilizers when used in combination, have a synergistic effect. The dosage of UV-329 in 0.10-1.0% (A highly effective light stabilizer, it has a broad UV absorption spectrum and low volatility .

3.4 For PS, polymethyl methacrylate, unsaturated polyester ( UPE ), rigid PVC, polycarbonate, ABS resin, etc, esp . In clear products or engineering plastics processed under high temperature .

3.5It has synergetic effect if used with antioxidant, which can raise heat and oxidization stabilities of the product . Usual amount to use is 0.01-1%.
