KR940005314A - Particulate Compositions and Methods of Improving Wetting of Particulates - Google Patents

Abstract

The present invention relates to a new and improved composition for releasing microparticles, the composition comprising microparticles; And one or more ammonium salt (s), boron salt (s) and / or effective metal salts in an amount effective to sufficiently increase the rate of penetration of the liquid into the particulates relative to the rate of penetration in the absence of salt (s). S). The presence of such salt (s) also results in a reduction of the wetting time and / or dispersion time of the particulates in the liquids. The present invention also provides a method of reducing the wetting time of particulates in a liquid by the use of said salt (s).
