Hazard Level & Hazards:
When we create or update chemical disposal entries, our H-code hazard list is generous. We list hazards that may be just below regular cutoffs and would otherwise normally be unlisted. We do this to provide hobbyists a wider scope of safety risks that may still be relevant, despite normally being omitted. Our GHS icons, however, are congruent with typical legal labeling requirements of the respective chemical.
Medium
- H302: Harmful if swallowed
- H317: May cause an allergic skin reaction
- H319: Causes serious eye irritation
- H401: Toxic to aquatic life
Disposal Method
Never put the liquid down any drains. Before you can throw photopolymer resins away you need to cure them. Place it in a clear plastic container and in the sunlight or under a UV lamp. The top will harden first make sure to allow the entire amount to solidify. You can flip if necessary. Once it’s no longer tacky you can throw it away in regular trash.Larger quantities should be taken to your local household hazardous waste (HHW) facility.Never pour resin-contaminated Isopropyl Alcohol (IPA) or water-washable rinse water down the drain. Put the dirty wash liquid in a clear container and leave it in the sun. The UV light will cause the resin particles to cure and settle at the bottom as sludge. Once it has settled, filter it through a coffee filter and you can reuse the liquid for your next wash. The sludge in the coffee filter should be left in the sun until it’s solid. Then it can be thrown away.
Neutralizing Agent
N/A – For spills, wear nitrile gloves. Ensure ventilation. Blot the liquid with paper towels and clean the surface with 90% IPA. Follow the disposal instructions for materials from the cleanup.
Storage Precautions
Store in a sealed opaque HDPE container. Store in a cool, dry place away from direct sunlight. Label with the date and type of resin.
Ideal Storage Container
HDPE. Review our chemical storage container guide for more information about container types and materials.
Other Names
UV resins, light-activated resins, or photo-curable resins
Additional Tips
- If your prints stay tacky after curing, you need to prevent oxygen in the air from interacting with the surface. Submerge your washed, dry print in a clear glass container of water or glycerin before putting it in the UV cure station. Oxygen can’t reach the surface through the liquid.
- Use a small 365nm UV flashlight for workstation cleanup. It flashes small spills into solids much faster than a 405nm light, making it easier to chip resin off your table or tools without it smearing.
- You can grind up your fully cured waste supports into a fine powder. Mix this powder with a tiny amount of liquid resin to create a structural bondo for filling gaps in large kits.
Incompatible Chemicals/Dangerous Combinations
- Strong Oxidizers (Bleach (NaClO), Concentrated Peroxides) Fire Hazard – Can react violently with the organic components in your resin. Mixing can cause a rapid, thermal runaway (extreme heat) that can ignite the resin or nearby materials.
- Strong Acids or Bases (Muriatic Acid (HCl), Drain Cleaner) Violent Reaction – Aggressively attacks the resin or triggers a premature polymerization. Releases high heat and toxic vapors.
