Kind Code:
Y2
Abstract:
Stable bitumen emulsions of their combinations with rubber latex, alkylphenylpolyglycolethers as stabilising agents and substances swelling in water such as aq. solns. of Na- or NH4-salts of polyacrylic acid, also contain 1-35%, pref. 2-20% urea. The emulsions formed are frostproof to ca -20 degrees C and retain their props. even after freezing solid in very cold weather and subsequent thawing. They may be used esp. in early spring and late autumn for soil mulching, spray-seeding of lawns etc. The urea acts as top fertilizer and saves extra work. The customary ammonia-losses in urea top-fertilisers are reduced because of the soil-clogging props. of the emulsions.
