Disposing of resin

Disposing of resin

Liquid resin

Dispose of resin when it has become too contaminated to be filtered, has reached the end of its lifetime, or has otherwise been made unsuitable for use.

Warning:

Resin and solvent may cause skin irritation or an allergic skin reaction. Wear gloves when handling liquid resin, resin-coated surfaces, or solvent. Wash skin with plenty of soap and water.

Caution:

Refer to the safety data sheet (SDS) and local authorities for guidance on disposing of resin and solvent. Liquid resin (whether pure liquid, dissolved in solvent, or partially cured) may be classified as hazardous waste in your region and shall be disposed of with care.

Disposal with a chemical waste stream

To dispose of liquid resin that has not been cured or dissolved in a solvent, add it to your chemical waste stream in accordance with all applicable regulations.

Disposal without a chemical waste stream

To dispose of liquid resin:

  1. Put on a new, clean pair of nitrile gloves.
  2. Pour a small amount of resin into a labeled, transparent, resin-safe container.
  3. Leave the container exposed to sunlight to cure for 1–10 days. Expose resin to 405 nm light and heat for the most effective curing. The liquid resin cures to solid material when exposed to light and heat.
  4. Dispose of the fully cured resin and container as household waste.

Notice:

  • Do not pour liquid or partially cured resin into drains or dispose of it with household waste.
  • Do not pour solvent (IPA, TPM) that contains dissolved resin into drains or dispose of it with household waste. Safe and appropriate disposal methods of used solvent vary by location.

To dispose of paper towels or other supplies that have come into contact with liquid resin, expose them to sunlight or UV light to cure the liquid resin and then dispose of them with household waste.

Cured resin

Cleaned parts and cured resin cannot be recycled. Discard cleaned parts and cured (hardened) resin as household waste.
