600 Series Silt Stop®

Applied Polymer Systems products harness the power of environmentally friendly materials to solve numerous water quality, erosion, and sediment challenges. Anionic polyacrylamide (PAM) is a polymer flocculant that can be used for a wide variety of erosion, sediment, and stormwater management applications. APS products bind, stabilize, and/or remove commonly problematic particles like sediment (clays, silt), metals, and nutrients to prevent erosion, clear water, and improve BMP performance. APS products are made and packaged in the United States, are drinking water quality (NSF/ANSI Standard 60 Certified), have been extensively toxicity tested by third party laboratories in accordance with EPA standards, and are safe for both terrestrial and aquatic organisms and environments.

Product Overview

APS 600 Series Silt Stop® is a group of soil specific, tailored polyacrylamide co-polymer emulsions for erosion control. They reduce and prevent erosion of fine particles and colloidal clays from the soil into stormwater.

Primary Applications

  • Mine Tailings and Waste Piles
  • Newly cleared Construction or Building Sites
  • Road and Highway construction
  • Hydroseeding and Water Truck application

Features and Benefits

  • Removes solubilized soils and clay from water
  • Prevents colloidal solutions in water when applied to the soil surface
  • Will reduce soil movement during rain event on moderate slopes
  • Binds cationic metals within the soil matrix, reducing solubilization
  • Reduces pesticide and fertilizer loss during rain events
  • Reduces wind borne dust conditions
  • Increases soil permeability and water penetration to shallow plants
  • Reduces operational and cleanup costs
  • Reduces environmental risk and compliance

Specifications / Compliances

  • NSF/ANSI Standard 60 Drinking Water Grade Chemical
  • Toxicity tested per EPA Guidelines
  • Made in the USA


  • 600 Series Silt Stop® is packaged in 5 gallon pails

Directions for Use

  • APS products should be matched to each site’s unique soil and/ or water. Please contact us to have your soil or water sample tested for FREE!
  • Shake well before opening as separation may have occurred.
  • APS 600 Series Silt Stop® Emulsions may be applied with hydroseeders, water trucks or other spraying devices. Spraying devices having a mechanical agitator or mixing apparatus or hydraulic recirculation will work best.
  • Pour emulsion into the water tank or hydroseeder filling water stream or with a mixing apparatus operating, and pour emulsion into the filled tank. Allow emulsion to mix for one – two minutes before application. Seed, fertilizer, and mulch should be added into hydroseeders before the emulsion has been added
  • APS 600 Series Silt Stop® Emulsion must be added at the end of the final mix and sprayed immediately. With the emulsion you must have 100% coverage
  • Caution – Do not exceed 1.5 gallons of emulsion / 1500 gallons as viscosity of the water may reduce spraying efficiency or damage spraying equipment.

Application Rates

  • Hydroseeding application rate (per acre coverage): varies by soil content and grade of slope
  • Gentle to Moderate slopes (0-4:1)
    • High Clay Content = 1-2 gallons 600 Series Silt Stop per acre
    • High Sand Content = 2-3 gallons 600 Series Silt Stop per acre
  • Steep Slopes (3:1 to 1:1)
    • High Clay Content = 1-2.5 gallons 600 Series Silt Stop per acre
    • High Sand Content = 2.5-3 gallon 600 Series Silt Stop per acre
