Dynaflush is a unique flushing solvent for urethanes. It is indispensable in a wide variety of cleaning applications in the urethane industry.

 

General:
Dynaflush is recommended for flushing uncured urethane residues and isocyanates. It is non-chlorinated, nonflammable (by U.S. Department of Transportation definition), non-carcinogenic, and non-ozone depleting. It replaces and improves on the performance of commodity solvents such as methylene chloride, acetone, methyl ethyl ketone (MEK), and 1,1,1-trichloroethane. Dynaflush can be used for extended periods, tolerate high resin loadings, and will reduce disposal costs.

It is also recyclable via vacuum distillation.

APPLICATIONS:
1. Dynaflush is especially effective for flushing mixing and metering equipment and feed lines, as it quickly and completely cleans polyols, crystallized isocyanates, and other urethane intermediates. However, in cleaning of isocyanate sides of equipment, Dynasolve Iso-Neutralizer should be used first if excessive amounts of liquid isocyanates are present.

2. Dynaflush is an excellent uncured epoxy flushing solvent as well.

DIRECTIONS FOR USE:
Flushing: Use Dynaflush as you would normally use any other flushing solvent. Mild heating of the solvent will product faster results. The use of compressed air for agitation of the solvent will also help to facilitate cleaning. If excessive amounts of liquid isocyanates are present, Dynasolve Iso-Neutralizer must be used first. Failure to use the Iso-Neutralizer may lead to gelling of the flushing solvents.

MATERIALS OF CONSTRUCTION:
Recommend: Teflon, butyl rubber, silicon rubber, Kalrez, mild steel, Halar, melamine, Nylon 101, polyethylene, polypropylene, Ryton (150°F or less).

Avoid: Viton, PVC, ABS, Buna-N, Durel, Hypalon, Kynar, Lexan, Lucite, Neoprene, Noryl EN-265, Noryl 731, PET, phenolic, polyester, polysulfone, polyurethane, Ultem, Valox.
