Guardian®

SUPERIOR GUAR GUM TACKIFIER

WITH LOW WATER USE

Guardian® – PRODUCT DESCRIPTION

Guardian™ is the portable SOIL STABILIZER SYSTEM of the future. This proprietary blend of natural polysaccharides called Guardian™ allows it to be a stand-alone soil stabilizer or used to tackify an infinite combination of native fiber sources. Guardian™ can be used creatively with a wide array of other options that are conducive to the environment and project.

For example Guardian™ could be used with the following:

• Cereal grain stalks and straw residue • Recycled cardboard and paper waste

• Sugar cane toppings • Blends of paper and virgin wood fiber

• Agricultural processing waste • Compost

• 100% REDUCTION IN SEDIMENT YIELD

When compared to the untreated bare soil condition on a 2:1 slope, the data demonstrates that an application of a hydraulic mixture composed of 1,000 lbs of wood fiber mulch, 2,800 gallons of water, 200 lbs of Guardian™ and 80 lbs of XL (Rantec Cross Linker) reduced erosion and sediment delivery by 100% when exposed to three consecutive 10-year storm events.

LOW WATER USE

Guardian™ has the specific advantage of minimal water requirement. If water consumption is limited or cost prohibited due to remote locations, then Guardian™ is your choice. Use less water and save time and money.

EASE OF MIXING

Guardian™ has been specially treated to allow ease of mixing with minimal agitation. Chemical tackifiers require costly liquid suspensions that add to the cost and do not contribute to product performance. Guardian™ can be added directly to water truck applications with a Rantec Eductor. The product can be vacuumed directly from the bag into the tank.

APPLICATION

Guardian™ allows the applicator to vary the tackifier and fiber application rate independently to

accommodate a wider range of slope and erosion options. Guardian™ is effective as a stand-alone soil binder for NPDES temporary soil stabilization.

ENDURING ADHESIVE

Guardian™ is a guar based tackifier which has been used for the past 30 years as an acceptable biodegradable alternative to latex emulsions and plastic polymer suspensions. Starch, plantago and

polyacrylamide systems will all re-dissolve once they are wetted again and will lose their bond. Guardian™ can be repeatedly soaked and still resist rewetting when used in conjunction with Rantec’s XL cross linker.

ENVIRONMENTAL COMPATIBILITY

Guardian™ will not form a crust that inhibits plant growth. Over the time necessary to establish permanent revegetation, Guardian™ will biodegrade into harmless components that will provide nutrients for future plant growth.

VISCOSITY AND ADHESIVE STRENGTH IN ONE PACKAGE

One aspect of tackifier performance often overlooked is the role of viscosity of the slurry:

1. Slurry flow is laminar and droplet size is increased. This creates an easily directed flow and

minimizes wind drift so that the Guardian™ goes where it is aimed and stays put once in contact

with the ground.

2. Guardian™ viscosity is critical to a uniform application. Runny slurries will drift and slide down

the slope once applied, just like paint that is too thin. Guardian™ produces slurry viscosity very

quickly and can be applied as soon as the hydroseeder is topped off. No waiting for testing.

3. Guardian™ is a non- linear polymer that exhibits shear thinning. When Guardian™ solutions

are sheared at higher rates during pumping thru fittings and nozzles, they actually exhibit less

pressure drop than basic water solutions. They also lubricate the slurry and increase the pumping

capacity of the circuit because of that feature.

4. Guardian™ thickens immediately after placement, remaining in place on the slope.

5. As slope increases additional viscosity is required to prevent sag. Guardian’s™ viscosity is

easily increased with small increases in concentration.

6. Soil penetration – Guardian™ is specifically formulaed for maximum soil penetration.

Guardian™ can be applied at 15 to 120 lbs in 1,000 gallons of water depending on the equipment capacity. When used as an overspray, mix Guardian™ at 40-180lbs in 1000 gallons of water with 150 to 300lbs per acre of mulch as a marker”.
