Light Stabilizer Tinuvin 622 in Polyethylene

This study presents an inexpensive and reagentless turbidimetric technique for the determination of Tinuvin 622 in polyethylene matrix. Tinuvin is dissolved in acetone, and water is added to it. The s

It is common practice to combine hindered amine light stabilizers (HALS) with UV absorbers (UVA) for optimal protection of coatings and plastics. The ratio of UVA and HALS strongly depends on the conc

The use of light stabilisers in traditional powder coatings cured with either TGIC or Primid can result in systems with greatly improved weathering resistance. This improvement in weatherability does
