Abstract:
An aqueous composition consisting essentially of:(a) an inorganic compound selected from colloidal silica, silicates of sodium, potassium, ammonium, alkali or alkaline earth metals or mixtures thereof, present in an amount from 2 to 95% by weight, based on the weight of the dry product; and(b) a fluoroelastomer consisting essentially of vinylidene fluoride (VDF) and at least another ethylenically unsaturated fluorinated comonomer, or a mixture of fluoroelastomers, consisting of vinylidene fluoride (VDF) and at least another ethylenically unsaturated fluorinated comonomer, and a non-elastomeric homopolymer of VDF or a non-elastomeric VDF copolymer consisting of vinylidene fluoride (VDF) and at least another ethylenically unsaturated fluorinated comonomer, present in an amount from 5 to 98% by weight based on the weight of the dry product, wherein the VDF monomer is present in an amount between 35 and 85% by moles.
