UV Stabilizer – polymers UV protection

what is UV stabilizer?

Except for the heat, products are exposed to light in most case, no matter its direct sunlight or light from the lamp. Thus UV protection for polymers is vital,  otherwise, the products could cracking,  yellowing and delamination due to  UV light degradation.

UV stabilizer contains two groups, the first is Ultraviolet Light Absorbers, also known as UVA or UV absorber, the second group is Hindered Amine Light Stabilizers which known as HALS or light stabilizers. They are used individually or as blends. UV absorber filters harmful UV light and helps prevent color change and delamination of coatings, adhesives, and sealants. Light Stabilizers trap free radicals once they are formed and are effective in retaining surface properties such as gloss and prevent cracking and chalking of paints. The combination of these two families is highly synergistic.  

 

what is UV stabilizers’ application and which to choose?

UV stabilizers are used in plastics, rubber, coatings, paint, adhesive, polymer, and different resins. UV absorber and light stabilizer are used individually or together to achieve the synergic effect.
