Urethane Cleaning Solvent

Dynasolve CU-6 is a formulated cleaning solvent used to remove cured urethane materials and flush uncured urethane materials. It is used primarily in spray polyurethane foam and industrial urethane cleaning applications. It is non-chlorinated, non-flammable (by U.S. Department of Transportation definition), and non-ozone depleting.

Cleaning Applications:

  • Spray polyurethane foam equipment cleaning
  • Industrial urethane removal and cleaning
  • Urethane processing equipment and line flushing
  • Polyurethane mold cleaning


  • More efficient than acetone, MEK & other solvents
  • High loading capacity and recyclability allows for reuse and reduces cost of ownership
  • Non Chlorinated, nonflammable (by U.S. DOT definition), and nonozone depleting.
  • Removes both cured and uncured urethane materials
  • Designed to be highly selective
  • High flash point

Materials removed: 

  • Cured urethane materials
  • Urethane based adhesives
  • Crystallized isocyanate
  • Uncured urethane materials

Product Usage Guidelines

Removing Cured Urethane Materials

  1. Immerse part in Dynasolve CU-6 at room temperature.
  2. Observe carefully. If cured urethane appears unaffected after 1 hour, heat solvents to 130°- 150°F (55° - 60°C).
  3. If urethane appears unaffected after 2 hours, call for technical support.

Removing Uncured Urethane Materials

  1. After ensuring that liquid isocyanate has been removed from the system by utilizing Dynasolve ISO-neutralizer, introduce room-temperature Dynasolve CU-6 to the system to remove polyols, uncured urethane, and other urethane intermediates.
  2. Mild heating of solvent will produce faster result.
