PolySpec® 196SL

PolySpec® 196SL is a high performance fluoroelastomer coating for use over Thiokol® Sealants where increased chemical resistance is required. It is recommended for resistance to many aggressive chemicals at elevated temperatures.

Recommended Uses 

  • Chemical containment dikes exposed to aggressive chemical spills
  • Chemical process areas
  • Chemical plants
  • Semiconductor facilities
  • Hazardous waste treatment, storage and unloading areas
  • Truck and rail loading/unloading areas


  • Retains flexibility even as concrete moves
  • Resistant to aggressive chemicals at service temperatures from -40ºF to 400ºF
  • Resistant to ozone, sunlight and UV radiation, maintaining superior bond and flexibility in out door applications
  • Achieves chemical resistance benefits of fluoroelastomer sealants at a lower cost
  • Excellent chemical resistance to concentrated sulfuric acid, 73% nitric acid, phosphoric and hydrochloric acid; also resists petroleum products, many chlorinated
  • solvents and aggressive chemicals such as aniline and phenol
