ortho-Nitrobiphenyl (ONB)
Monsanto ONB possesses an unusually wide range of compatibility. It can be used alone, or with other plasticizers — is applicable to the entire range of synthetic resins, from the cellulose esters and ethers through the vinyls and vinyl copolym e r s — is compatible with alkyds and some synthetic rubbers. It is suggested for use as: 1. A l o w cost, active plasticizer for v i n y l resins 2. A camphor substitute in cellulose nitrate compositions 3. A plasticizer in cellulose acetate molding compositions 4. A plasticizer in lacquer coatings to improve water, acid and alkali resistance 5. A stabilizer with some plasticizing action in varnishes Other uses may suggest themselves when you study the table of physical and chemical properties included here . . .
