organosol
(ɔːˈgænəsɒl)
[a. G. organosol (E. A. Schneider 1892, in Ber. d. Deut. Chem. Ges. XXV. 1164): see organo- and sol n.6]
A dispersion in which the dispersion medium is an organic liquid; spec. one of particles of a synthetic resin in a liquid consisting of plasticizer and volatile components, which can be converted into a solid plastic simply by heating (cf. plastisol).
| 1892 Jrnl. Chem. Soc. LXII. 775 Organosol Ag ([in] ethyl alcohol) is formed by the dialysis of the hydrosol in absolute alcohol. 1931 E. S. Hedges Colloids xiv. 192 When the organosols are treated with a liquid which is soluble in the dispersion medium, but does not dissolve the disperse phase, the latter is precipitated. 1946 Mod. Packaging Mar. 262/2 Conversion..from solution coating to an organosol dispersion more than doubled the unit output of one modern coating plant. 1960 Times Rev. Industry May 23/2 The best known of the organosol coatings are the vinyl synthetic resin types. 1963 H. R. Clauser Encycl. Engin. Materials 454/2 Several plants are using spread coaters for the application of organosols and plastisols to strip steel to provide materials competitive with the light metals and plastics. 1972 Materials & Technol. V. xi. 338 Organosols are easier to spray in conventional equipment, and give thinner films with a greater range of flexibility and hardness. |
