DMSO for Polyurethane Cleanup


Tests conducted at an independent laboratory confirm the effectiveness of Gaylord Chemical DMSO and DMSO-based formulations for dissolving a wide variety of both cured and uncured polyurethane residues. DMSO’s performance, combined with its formulation versatility and safety profile, make it an excellent choice for polyurethane flush and clean-up.

The tests evaluated the effectiveness of the twelve most common solvents and formulated solvent blends which are utilized by solid elastomer, flexible foam, and rigid foam processors. The studies examined each solvent’s ability to flush key raw materials and to swell or dissolve cured elastomers.
