Portafill® H 10
- CASE Ingredients Features
- Good Brightness
- Chemical Name
- Huntite
Portafill® H 10 is produced from a carefully selected, naturally occurring, platy, sedimentary mineral consisting predominantly of partially hydrated magnesium-calcium carbonate. The standardized quality of Portafill® H is guaranteed by means of an ISO 9001-certified quality management plan. The chemical composition of raw material and product is closely monitored, and particle size is kept within a narrow range. 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.
