Ultraviolet light can initiate chemical reactions in polymers which result in their breakdown and loss of their chemical and physical properties. The Tinuvin® range of light stabilizers provides effective protection against UV absorption for furniture and flooring coatings for both interior and exterior coating applications.
The key classes of light stabilizers are typically described as either ultraviolet light absorbers (UVAs) or hindered amine (or amide) light stabilizers (HALS). Those two classes are often combined in formulations to provide a level of stability which is higher than what would be achieved by using either type alone. Such combinations are widely and effectively used in furniture and flooring coatings.
