2.3 Clean-Up Solvents and Resin Diluents
WARNING
A hazardous situation may be present in your pressurized fluid system! Hydrocarbon
Solvents can cause an explosion when used with aluminum or galvanized components in
a closed (pressurized) fluid system (pump, heaters, filters, valves, spray guns, tanks,
etc.). The explosion could cause serious injury, death and/or substantial property
damage. Cleaning agents, coatings, paints, etc. may contain Halogenated Hydrocarbon
Solvents. Some Magnum Venus Plastech spray equipment includes aluminum or
galvanized components and will be affected by Halogenated Hydrocarbon Solvents.
A. There are three key elements to the Halogenated Hydrocarbon (HHC) solvent hazard.
a. The presence of HHC solvents. 1,1,1 – Trichloroethane and Methylene Chloride are
the most common of these solvents. However, other HHC solvents are suspect if
used; either as part of paint or adhesives formulation, or for clean-up flushing.
b. Aluminum or Galvanized Parts. Most handling equipment contains these
elements. In contact with these metals, HHC solvents could generate a corrosive
reaction of a catalytic nature.
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.
