Granufin® free-flowing pigments and the Granumat® concrete color metering system are so innovative, they were granted patent 4,946,505. Granufin® is the only pigment granule with a binding ingredient that stays intact during transport and metering and then enhances color development when mixed into concrete.
The primary ingredient is concentrated Synthetic Iron Oxide pigment, high-quality Red, Yellow or Black grades that meet or exceed ASTM, DIN and British standards for fade resistance and concrete compatibility. Carbofin® is a granulated carbon made in a proprietary process to prevent carbon fading. Granufin® Magnit D Super is enhanced with Carbofin for extra tinting power. The binder ingredient in all granulated products is a commonly used concrete plasticiser which rapidly breaks down in water and increases tint strength above ordinary powders.
Four primary colors are standard: Black, Yellow, Light Red and Medium Red. These can be combined on-site to make a wide spectrum of popular concrete colors. In addition, there is a selected range of brown, buff, gold and tan Granufin® colors available in 55 pound bags as well as bulk-sacks for clean and convenient handling without automatic systems. Granulated versions of Titanium Dioxide White and Chromium Oxide Green are also available to complete the color palette.
Every bulk-sack of Granufin® is shipped with its own inspection certificate verifying color shade and tint strength meet our precise quality standards.
Granufin® micro-granules pack into a volume that is nearly 1/2 the size of powder pigment, increasing storage space available in your operation.
