DMS (Dimethyl Succinate) and DMSEB (Dimethyl Sebacate) for Light Stabilizers

DMS (Dimethyl Succinate) and DMSEB (Dimethyl Sebacate) are intermediates widely used in light stabilizers. Light can cause major damage to coatings via photo-oxidation and the resulting discoloration. In wall paints or inks, for example, yellowing or fading can ultimately lead to surface degradation, including cracking, chalking, and loss of gloss. By adding light stabilizers to coatings or plastics, manufacturers can improve the stability of their coating and prolong the lifespan of their product.

Applications

Hindered Amine Light Stabilizers (HALS)

DMS and DMSEB are key components in the production of HALS systems. HALS are radical scavengers used to protect polymer coatings from photo-oxidation damage and thus reduce the deterioration of materials. These light stabilizers are mainly used in plastics and in automotive and exterior coatings.
