I have seen just a little bit of contaminated A side lead to replacing 260 ft of hose plus days of tearing apart the proportioner to clean out the contaminated A from heaters, proportioners and pumps. Go to polyurethane.org and download AX 151 Guideline for Responsible Disposal of MDI and container for specific information on how to dispose of MDI.)
