Resinex K-8 FG
™
Strong acid cation softening resin
Resinex™ K-8 FG is a high purity, premium grade, pretreated, strongly acidic gel-type cation exchange resin specially
designed for residential drinking water treatment. The K-8 FG is a bead type, crosslinked, polystyrene divinylbenzene resin
that offers excellent bead integrity and very low extractables. The product is highly suitable for a wide variety of drinking
water treatment applications. Resinex™ K-8 FG has a light amber color and is specially pretreated to remove taste, odor
and color throw. Resinex™ K-8 FG meets the requirements of FDA regulation CFR section 21, §173.25.

Capacity and Hardness Leakage graphs are shown assuming a service flow of 4 gpm/ft3 (32 l/h/l) and total dissolved solids of 400 ppm and 20 grains of total hardness. The hardness leakage will increase
and the capacity will decrease while increasing total dissolved solids and total hardness.
NOTICE If this product is to be used for potable water treatment, or any food grade application, a special procedure must be applied for the initial run. Please ask your nearest Jacobi office for this
