Important Acid Acid Catalyst
Important Important Acid
The PD2K AC4002 Proportioner is designed for acid catalysts ("acid") currently used in two-component,
wood-finishing materials. Current acids in use (with pH levels as low as 1) are more corrosive than earlier acids.
More corrosion-resistant wetted materials of construction are required, and must be used without substitution, to
withstand the increased corrosive properties of these acids.
Acid Catalyst Acid Acid Catalyst Catalyst Conditions Conditions Conditions
Acid is flammable, and spraying or dispensing acid creates potentially harmful mists, vapors, and atomized
particulates. To help prevent fire and explosion and serious injury:
• Read and understand the acid manufacturer's warnings and Safety Data Sheet (SDS) to know specific hazards
and precautions related to the acid.
• Use only genuine, manufacturer's recommended acid-compatible parts in the catalyst system (hoses, fittings,
etc). A reaction may occur between any substituted parts and the acid.
• To prevent inhalation of acid mists, vapors, and atomized particulates, everyone in the work area must wear
appropriate respiratory protection. Always wear a properly fitting respirator, which may include a supplied-air
respirator. Ventilate the work area according to instructions in the acid manufacturer's SDS.
• Avoid all skin contact with acid. Everyone in the work area must wear chemically impermeable gloves, protective
clothing, foot coverings, aprons, and face shields as recommended by the acid manufacturer and local regulatory
authority. Follow all acid manufacturer recommendations, including those regarding handling of contaminated
clothing. Wash hands and face before eating or drinking.
• Regularly inspect equipment for potential leaks and remove spills promptly and completely to avoid direct contact
or inhalation of the acid and its vapors.
• Keep acid away from heat, sparks, and open flames. Do not smoke in the work area. Eliminate all ignition
sources.
• Store acid in the original container in a cool, dry, and well-ventilated area away from direct sunlight and
away from other chemicals in accordance with acid manufacturer's recommendations. To avoid corrosion of
containers, do not store acid in substitute containers. Reseal the original container to prevent vapors from
contaminating the storage space and surrounding facility.
Moisture Sensitivity Moisture Moisture Sensitivity of of of Acid Sensitivity
Acid catalysts can be sensitive to atmospheric
moisture and other contaminants. It is recommended
the catalyst pump and valve seal areas exposed to
atmosphere are flooded with ISO oil, TSL, or other
compatible material to prevent acid build-up and
premature seal damage and failure.

NOTICE
NOTICE NOTICE
Acid build-up will damage the valve seals and
reduce the performance and life of the catalyst
pump. To prevent exposing acid to moisture:
• Always use a sealed container with a desiccant
dryer in the vent, or a nitrogen atmosphere.
Never store acids in an open container.
• Keep the catalyst pump and the valve seals filled
with the appropriate lubricant. The lubricant
creates a barrier between the acid and the
atmosphere.
• Use only moisture-proof hoses compatible with
acids.
• Always lubricate threaded parts with an
appropriate lubricant when reassembling.
