Important Acid Catalyst Information
Regulator model 26A086 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 Conditions
Moisture Sensitivity of Acid
Catalysts
Acid catalysts can be sensitive to atmospheric moisture
and other contaminants.
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.
NOTICE
Acid build-up will damage the seals and reduce the
performance and life of the regulator. 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.
• Use only moisture-proof hoses compatible with
acids.
• Always lubricate threaded parts with an
appropriate lubricant when reassembling.
