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

light stabilizers for waterborne clear coats
As a consequence of regulatory pressure to reduce solvent emissions, there is high growth rate of “compliant technologies” such as waterborne (WB) coatings. However, a change from conventi

Hindered Amine Light Stabilizer
In the absence of stabilizers, many polymer systems such as polypropylene have relatively poor UV stability. Other polymers such as polyethylene, styrenics, polyamides and polyurethanes also benefit f

Determination of a polymeric light stabiliser in polypropylene
Eine Methode zur Gehaltsbestimmung des polymeren Lichtschutzmittels Chimassorb 944 in Polypropylen wird vorgestellt. Die Polymermatrix wird in heißem Dekalin gelöst und durch Abkühlen

antioxidants and light-stabilisers
A scheme was devised for the identification of 22 common antioxidants and light-stabilisers in polyolefins. The separation of these stabilisers was performed by isocratic reversed phase high-performan

light stabilizers in pigmented coatings
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

An evaluation of the effect of light stabilisers on the exterior durability of polyester powder coatings for the architectural market
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

Use of reactable light stabilizers to prevent migration and to improve durability of coatings on plastic substrates
These studies investigate the migration of both nonreactable and reactable UV absorbers (UVAs) and hindered amine light stabilizers (HALS) in fully formulated 2K urethane coatings applied on thermopl

The Use of Accelerated Tests in the Evaluation of Antioxidants and Light Stabilizer
esting of plastics generally involves accelerated methods whose greatest merit is their ability to yield experimental data rapidly. The results may in some cases be of no help in determining the usef

High Performance Light Stabilizer
a blend of UV absorber and HALS, is developed by Everlight Chemical Industrial Corporation (ECIC) specifically for waterborne clear coats. Southern Pine was chosen for its popularity in the region. D
