Our portfolio contains two types of light stabilizers: Ultraviolet Light Absorbers (UVA) and Hindered-Amine Light Stabilizers (HALS). Based on the nature of the.
(WF) composites (with and without photo-stabilizers; hindered amine light . The use of WPC as building products has resulted in concern about the . photo-stabilizers such as UV absorbers (UVA) and hindered amine light stabilizers (HALS).
Keywords: WPCs; Hindered amine light stabilizer; Ultraviolet absorber; Zinc . (HALS) and ultraviolet absorbers (UVA), are often added to WPC formulations to.
used in WPC processing include lubricants, colorants, light stabilizers, anti oxidants ... 1995). A relatively new class of materials, hindered amine light stabilizers . that the addition of HALS to the composites did not affect color change caused.
