spirits 50%/15.0 Plastisols or organosols are prepared by mixing the ingredients in a heavy-duty mixer having higher shear rather than high speed. The vinyl resin is added in portions and folded quickly in the plastisol with slow stirring until a smooth paste, free of agglomerates, is obtained. Deaeration, if necessary, should be carried out at this point. With high pigment loads and/or nonmigrating plasticizers addition of solvent may be desirable to obtain the proper viscosity for coating (organosol). Mineral spirits, aromatics, DIBK or mixtures thereof are useful. A minimum of solvent should be used: solvent addition represents the last step in the organosol preparation. The following formulation has been successful for the preparation of a 3 to 4-mil cast vinyl film of exceptional fluorescent brightness "Velva-Glo" pigment R-103-G or R-203-G/34.0 Mix with AC-33, acrylic emulsion/43.0 "V.G." pigment R-103-G or R-203-G/35.0 Vin |
