AQUEOUS DISPERSIONS OF PRECIPITATED CALCIUM CARBONATE |
摘要 |
A stable aqueous dispersion of platy particles and precipitated calcium carbonate, a method of producing the same and uses of the dispersion. The aqueous dispersion comprises 50 to 95 parts by weight of platy particles; and 5 to 50 parts by weight of precipitated calcium carbonate particles having an average diameter of 30 to 60 nm. The dispersion has a dry matter content of more than 30 % by weight of the dispersion, and a Brookfield viscosity (100 rpm) of 200 to 5000 cP. The dispersion is suitable for forming barrier coatings on a substrate, having properties of improved gas barrier and improved mineral oil barrier. |
