Disposal

  • Make every effort to use all mixed resin (measure, dispense, and mix only the needed volume to avoid generating excess waste)
  • Any uncured mixture should be allowed to fully cure to a solid state before disposing as waste
  • Dispose of process materials in the same manner.
  • Do not pour uncured substances down the drain or allow them to enter the sewer line, waterway, or watershed
  • Any uncured liquid waste must be disposed of as a hazardous waste, including contaminated process materials
  • A labeled, designated waste container and satellite accumulation area must be established, and coordination with an environmental waste company must be made for pick-up

Other Notes

  • Do not eat, drink, or smoke when using this product. Wash hands thoroughly after use.
  • A person with a history of skin sensitization, asthma, or respiratory disease should not use this product.
  • Never use near an open flame or possible ignition source. The decomposition products from burning these materials are extremely toxic and irritating.
