Resorcinol Monobenzoafe Form white crystalline solid Melting point 132-135°C. Solubility most polar organic solvents This ultraviolet inhibitor is particularly useful in plast ic appl icat ions r e q u i r i n g a high degree of transparency. We wouldn't t ag it, but someone did—"a colorless guard." Can be used with cellu-losics, vinyl, and certain polyesters.

Solubility non-polar and polar organic solvents A highly effective ultraviolet light inhibitor for both polyethylene and polypropylene. Also shows promise in polyvinyl chloride, polystyrene, polyesters, and in surface coatings containing such film formers as cellulose acetate butyrate, cellulose ni t ra te and acrylic resins.

Solubility polar organic solvents We hear th i s one pro tec t s epoxy-type res ins against the harmful effects of ultraviolet radiation. Our own accelerated and outdoor tests suggest use in polystyrene and unsaturated polyesters, also cellulosics.
