Light stabilizers new from IMPAG

Stabilizers are used for material protection just about everywhere in the world and in a multitude of applications. Antioxidants and light stabilizers are used, for example, in the coatings, packaging, and electronics industries, as well as in various construction materials and the automotive industry. 

In our new cooperation with the Rianlon Corporation, one of the largest manufacturers of antioxidants and light stabilizers (UV absorbers and HALS), we now offer our customers in Switzerland and in Liechtenstein a wide selection of additives for challenging material stabilization applications in the plastics and CASE (Coatings, Adhesives, Sealants, and Elastomers) industries.

With our partner Rianlon, we guarantee high material availability even in times of short supply thanks to Rianlon’s five production locations, which ensure that each product can be manufactured in at least 2 locations. 
Rianlon furthermore takes sustainability and environmental protection seriously: the company has a complete infrastructure for waste gas processing and wastewater treatment, as well as waste treatment facilities In addition to ISO 14001 and OHSAS 18001 certification, Rianlon has received excellent ratings in onsite and online evaluations by the TFS Initiative (TFS onsite evaluation: 89%; ECOVADIS method evaluation: Gold Medal).
