Five Polyaspartic Formulations to Meet a Variety of Performance Demands

Rock-Tred’s Chem-Thane line of polyaspartic coatings is designed to meet a variety of installation requirements in diverse environments. Whether the job requires a low temperature cure in a freezer, a flexible finish over a Rock-Tred Soft Floor, or a hot and humid outdoor install on a patio, Rock-Tred has formulated a system to meet the challenge.  

There are some common traits shared among all Chem-Thane polyaspartic coatings:

  • They have superior UV resistance, so they can be installed inside or outdoors without yellowing, changing color or chalking. 
  • They possess excellent clarity and will cure to a truly water-clear finished film. 
  • All are high solids coatings that aren’t thinned with strong smelling, non-exempt solvents. 
  • When compared with many competitors’ polyaspartic coatings, Rock-Tred’s line has significantly lower VOC content and does not produce the harsh solvent odors many people expect.

Selecting which coating to use primarily depends on the installation environment and the type of system being installed. Consider the following tips to start, and for more in-depth information, reach out to your Rock-Tred sales rep.

Series 500-50 Chem-Thane P-50

  • Recommended for warmer installations between 50° - 90°F and/or when the relative humidity is elevated. 
  • 85% solids and can be installed in thicknesses from 8 – 20 mils WFT per coat.
  • May be applied directly to properly prepared concrete without the addition of Chem-Thane P-50 Viscosity Reducer.
  • Most often used as a non-yellowing finish coat over both indoor and outdoor decorative applications, such as flake and colored quartz broadcast systems. 
  • Used when a higher building coating than polyurethane is required, but when high abrasion and elevated chemical resistance are also needed. 
  • Used when a faster dry time is required than a typical epoxy coating.     

  Series 500-80 Chem-Thane P-80

  • Recommended as a thin film high-performance finish coat with jobsite temperatures between 55° - 85°F. 
  • 80% solids and limited to application thicknesses between 5 - 12 mils WFT per coat.
  • Not recommended as a self-priming coating, but can be used as a body/broadcast or final coat in a variety of solid color or decorative systems. Since it should not be applied heavier than 12 mils WFT, there are better choices within Rock-Tred’s line to grout and seal over full broadcast quartz and flake systems.
  • Most often used as a lower cost, thin mil broadcast coat or finish coat when non-yellowing and color stability are required.
  • Provides excellent abrasion resistance and very good chemical resistance in both clear and pigmented versions. 
  • Performs very well as a thin mil solid color finishing coat after field tinting with Rock-Tred’s Universal Colorants.

  Series 500-100 Chem-Thane P-100

  • Provides the same benefits as our Chem-Thane P-50, but is designed for use in cooler and lower humidity environments, or when a faster cure is needed. 
  • No sacrifice in clarity, color stability, abrasion or chemical resistance when using P-100 instead of P-50.     
  • Recommended for installations between 40° - 70°F without elevated humidity. When jobsite conditions are humid and above 70° P-100, it will cure quickly and may be hard for installers to finish evenly.   
  • 90% solids and can be installed in thicknesses from 8 – 20 mils WFT per coat.
  • May be applied directly to properly prepared concrete after the addition of Chem-Thane P-100 Viscosity Reducer.

Series 500-200 Chem-Thane P-200

  • Similar to our Chem-Thane P-100, but designed for use in very cold temperatures. 
  • Only recommended for installation temperatures between 0° - 40°F without elevated humidity. Will set up too fast for normal use above 40°F and may also develop a highly stippled appearance when applied in temperatures warmer than 60°F.  
  • 89% solids and can be installed in thicknesses from 8 – 20 mils WFT per coat.
  • May be applied directly to properly prepared concrete after Chem-Thane P-200 Viscosity Reducer is added in the correct amount. 
  • Can also be used as body/broadcast or finish coat in a variety of solid color or decorative systems.  

Series 570 Chem-Thane P-Flex

  • Unique among the polyaspartic line, P-Flex remains highly flexible but extremely tough and long-wearing. 
  • Provides the same exceptional clarity, gloss and color retention as the other Rock-Tred polyaspartics, but does not become rigid, making it the ideal finish coating for Rock-Tred’s Soft-Floor.
  • Has a lower chemical resistance than our other polyaspartics, but is resistant to most common chemicals found in household, commercial and light manufacturing facilities. 
  • 97% solids and can be installed in thicknesses from 8 – 15 mils WFT per coat.
  • Not recommended as a direct-to-concrete coating, but can be used as a body/broadcast or finish coat in a variety of solid color or decorative systems.
