Resorcinol Monobenzoafe Form white crystalline solid Melting point 132-135°C. Solubility most polar organic solvents 1
This ultraviolet inhibitor is particularly useful in plastic a p p l i c a t i o n s r e q u i r i n g a h i g h d e g r e e of transparency. We wouldn't t a g it, b u t someone did—"a colorless guard." Can be used with cellulosics, vinyl, and certain polyesters.

A highly effective ultraviolet light inhibitor for both polyethylene and polypropylene. Also shows promise in polyvinyl chloride, polystyrene, poly esters, and in surface coatings containing such film formers as cellulose acetate butyrate, cellulose nitrate and acrylic resins.
