Mayzo provides a variety of UV absorbers, which are useful to protect adhesives, plastics, coatings, and elastomers from the damaging effects of outdoor weathering that result from exposure to ultraviolet light.
- As their name implies, these additives function by competitive absorption of damaging UV light.
- Combinations of UV absorbers with other kinds of light stabilizers (for example hindered amine light stabilizers, or HALS) are often used in order to attain the best resistance to weathering.
Overview
BLS 99-2 is a liquid benzotriazole UV absorber that provides outstanding light stability to industrial and automotive coatings.
