Emulsifiable "Oxazoline" Wax OWR-150E can be formulated readily into true latex-type emulsions either by the water-to-wax or wax-to-water methods. In the water-to-wax method, for example, 200 lb of Wax OWR-150E is melted at 105'C (221'F) together with 50 lb of a nonionic emulsifying agent such as "Tergitol" NPX or "Igepal" CO-730. After the melt has cleared, add in small portions 12 lb of a 20% KOH solution with vigorous agitation to minimize frothing. After 15 minutes add 738 lb of hot water (95-100'C) in small portions. To complete the emulsification agitate for an additional 15 minutes at 95-100'C, then allow to cool to room temperature while slow agitation is maintained continuously.
Strain the cooled product, and store the homogeneous colloidal emulsion in polyethylene-lined containers to prevent contamination. the resultant latex emulsion will have a pale, opalescent appearance and will be free of suspended solids. A typical emulsion should be stable several months at room temperature, but should b |
