Permanent antistatic coating and coated polymeric film

摘要

The invention relates to a permanent antistatic composition, a thermoplastic film having the antistatic coating thereon, and a method for priming a thermoplastic film with the antistatic composition. The antistatic composition comprises: from 2 to 11% by weight of an antistatic copolymer; from 0 to 0.45% by weight of an antistatic compound; from 0.25 to 2% by weight glycidoxy silane; from 0.3 to 2% by weight spherical silica particles having an average diameter of 10-100 nanometers; and water, or a mixture of water and organic solvent, wherein the total weight percent of all components equals 100%.
