Suspension aqueous colloidal carbon black gas, stable to freezing and storage.

摘要

aqueous suspension colloidal carbon black gas, stable to freezing and storage, characterized in that it consists of 2-30% by weight of a carbon black gas, 0-40% by weight of another carbon black, a supporting additive to dispersion, which is a copolymer of styrene and acrylic acid, a biocide and water, and the zeta potential is less than -10 mV, the surface tension is greater than 50 mN / m and the average size of particles is less than 200 nm.
