USE & PRACTICE
- Allow solvent to become "dirtier" before recycling.
- Install additional spray lines to reduce cleanout Install disposable liners in buckets Install funnel into bucket to catch acetone spray.
- Install gun cleaning tank/unit Install two-bucket wash; one clean and one dirty.
- Keep lids on soaking buckets.
- Ration solvent or other material.
- Reduce number of cleaning units/buckets.
- Remove solid resin by hand prior to solvent wash.
SOLVENT ALTERNATIVES
- Use citrus-base solvent in place of acetone.
- Use diacetone alcohol in place of acetone.
- Use dibasic acid ester in place of acetone.
- Use emulsifier in place of acetone.
- Use ethyl ethoxy propionate in place of acetone.
- Use isopropanol in place of acetone.
- Use propylene carbonate in place of acetone.
WASTE MANAGEMENT
