| Granufin® Pigment Granules
|
|
The first dry, micro-granulated color that combines the flowability of liquid with the advantages of powder.
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.
A Complete System
The Granufin®/Granumat® color system includes Granufin® micro-granulated pigment and Granumat® dosing systems (instert link to Granumat heading), which automatically weighs and transports pigment from bulk storage directly to the concrete mixer in a completely enclosed automated batching operation. For many concrete producers, automated metering can be a more economical method for producing colored concrete. Granufin® colors are free-flowing, easy to handle and virtually dust-free for a cleaner manufacturing plant. They come in bulk super-sacks weighing between 680 to 1,200 Kilos to further minimize transportion and handling costs.
Low-Dust Technology
Granufin® begins with highly concentrated pigments that are turned into a liquid with high-speed grinding equipment that coats individual pigment particles with color-activating agents. The liquid is then sprayed into fine droplets and dried. It is during this spray-drying process that micro-granules are formed and the color-activating agent solidifies, binding individual pigment particles together into nearly perfect spheres with a water-receptive surface that range in size up to 300 microns. When stored and transported, granules stay hard. When wet, they rapidly dissolve into the mix.
Proven Ingredients
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.
A Shade for All Users
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.
Consitant Color
Every bulk-sack of Granufin® is shipped with its own inspection certificate verifying color shade and tint strength meet our precise quality standards.
Double the Density
Granufin® micro-granules pack into a volume that is nearly 1/2 the size of powder pigment, increasing storage space available in your operation.
Contains No Water
Free-flowing, low-dust Granufin® micro-granules Up until now, the easiest way to automate color metering was to install a liquid color system. With Granufin®, now you can automate without the hassle of making slurry-on-site or purchasing premanufactured slurries which contain up to 40% water. In some zero-slump manufacturing operations, the water added by slurry is enough to cause mix problems. With Granufin® free-flowing granules and the Granumat® metering system you get all the handling advantages of liquid without the added water. |
