Particle shape, fineness and high brightness make PORTAFILL® H a very efficient extender for TiO2 in paint, paper and board applications. Its platy particle shape and very fine particle size make PORTAFILL® H an effective rheology modifier in aqueous suspensions and other fluids. It is therefore valued for applications in a/o adhesives, sealants and plastisols.
