C. Prevent contamination of MEKP with other materials, including polyester over spray and
sandings, polymerization accelerators and promoters, brass, aluminum and non-stainless
steels.
D. Never add MEKP to anything that is hot, since explosive decomposition may result.
E. Avoid contact with skin, eyes and clothing. Protective equipment should be worn at all
times. During clean-up of spilled MEKP, personal safety equipment, gloves and eye
protection must be worn. Fire fighting equipment should be at hand and ready.
F. Avoid spillage, which can heat up to the point of self-ignition.
G. Repair any leaks discovered in the catalyst system immediately, and clean up the leaked
catalyst at once in accordance with the catalyst manufacturer’s instructions.
H. Use only original equipment or equivalent parts from Magnum Venus Plastech in the
catalyst system (i.e.: hoses, fitting, etc.) because a dangerous chemical reaction may result
between substituted parts and MEKP.
I. Catalyst accumulated from the purging of hoses or the measurement of fluid output
deliveries should never be returned to the supply tank, such catalyst should be diluted with
copious quantities of clean water and disposed of in accordance with the catalyst
manufacturer’s instructions.
The extent to which the user is successful in accomplishing these ends and any additional
recommendations by the catalyst manufacturer determines largely the safety that will be
present in his operation.
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.
