Tests Confirm that Gaylord Chemical's DMSO
is highly effective in removing Polyurethane Flush
& Clean-up Residues
Tests conducted at an independent laboratory confirm the effectiveness of Gaylord
Chemical Company, L.L.C.'s
DMSO and DMSO-based formulations for dissolving
a wide variety of both cured and uncured polyurethane residues. DMSO's perform-
ance, 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 for-
mulated 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.
DMSO and DMSO-based Formulations:
- increase the speed and completeness of removal
Get Back In Service Faster !
- remove the widest range of urethane components and formulations
Inventory fewer cleaners !
- are less corrosive and toxic than similarly performing alternatives
Reduced Risk To Equipment & Workers !
- are more environmentally friendly than alternatives
