Product Description
Chiguard® 353 CAS 41556-26-7 & 82919-37-7
Description
Chiguard® 353 is the first liquid light stabilizer of hindered amine light stabilizer type on the market. It provides excellent light stability and long-term thermal stability for a variety of coatings by using a free radical scavenging mechanism similar to hindered phenols. Its effectiveness can be greatly enhanced by adding UV absorbers or nickel-containing stabilizers.
