b. Equipment capable of withstanding pressure. When HHC solvent contact
aluminum or galvanized parts inside a closed container such as a pump, spray
gun, or fluid handling system, the chemical reaction can, over time, result in a
build-up of heat and pressure, which can reach explosive proportions.
When all three elements are present, the result can be an extremely violent explosion. The
reaction can be sustained with very little aluminum or galvanized metal; any amount of
aluminum is too much.
A. The reaction is unpredictable. Prior use of an HHC solvent without incident (corrosion or
explosion) does NOT mean that such use is safe. These solvents can be dangerous alone
(as a clean-up or flushing agent) or when used as a component or a coating material. There
is no known inhibitor that is effective under all circumstances. Furthermore, the mixing of
HHC solvents with other materials or solvents, such as MEKP, alcohol, and toluene, may
render the inhibitors ineffective.
B. The use of reclaimed solvents is particularly hazardous. Reclaimers may not add any
inhibitors. Also, the possible presence of water in reclaimed solvents could feed the reaction.
C. Anodized or other oxide coatings cannot be relied upon to prevent the explosive reaction.
Such coatings can be worn, cracked, scratched, or too thin to prevent contact. There is no
known way to make oxide coatings or to employ aluminum alloys, which will safely prevent
the chemical reaction under all circumstances.
D. Several solvent suppliers have recently begun promoting HHC solvents for use in coating
systems. The increasing use of HHC solvents is increasing the risk. Because of their
exemption from many State Implementation Plans as Volatile Organic Compounds
(VOC’s), their low flammability hazard, and their not being classified as toxic or carcinogenic
substances, HHC solvents are very desirable in many respects.
WARNING: Do not use Halogenated Hydrocarbon solvents in pressurized fluid
systems having aluminum or galvanized wetted parts.
NOTE: Magnum Venus Plastech is aware of NO stabilizers available to prevent
Halogenated Hydrocarbon solvents from reaction under all conditions with aluminum
components in closed fluid system. TAKE IMMEDIATE ACTION… Halogenated
Hydrocarbon solvents are dangerous when used with aluminum components in a
closed fluid system.
A. Consult your material supplier to determine whether your solvent or coating contains
Halogenated Hydrocarbon Solvents.
B. Magnum Venus Plastech recommends that you contact your solvent supplier regarding
the best non-flammable clean-up solvent with the heat toxicity for your application.
C. If, however, you find it necessary to use flammable solvents, they must be kept in
approved, electrically grounded containers.
D. Bulk solvent should be stored in a well-ventilated, separate building, 50 feet away from
your main plant.
E. You should allow only enough solvent for one day’s use in your laminating area.
