Important Acid Catalyst Information
Regulator model 26A081 is designed for acid catalyst ("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 is flammable, and spraying or dispensing acid creates potentially harmful mists, vapors, and
atomized particulates. To help prevent fire and explosion and serious injury:
D Read and understand the fluid manufacturer's warnings and Safety Data Sheet (SDS) to know
specific hazards and precautions related to the acid.
D 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.
D 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.
D 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 fluid manufacturer recommendations, includ-
ing those regarding handling of contaminated clothing. Wash hands and face before eating or
drinking.
D Regularly inspect equipment for potential leaks and remove spills promptly and completely to avoid
direct contact or inhalation of the acid and its vapors.
D Keep acid away from heat, sparks, and open flames. Do not smoke in the work area. Eliminate all
ignition sources.
D 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 recommendation. To avoid
corrsion 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 of Acid Catalysts
Acid catalysts can be sensitive to atmospheric moisture and other contaminants.
Acid build–up will damage the seals and reduce the performance and life of the regulator. To prevent exposing
acid to moisture:
D Always use a sealed container with a desiccant dryer in the vent, or a nitrogen atmosphere. Never store acids
in an open container.
D Use only moisture–proof hoses compatible with acids.
D Always lubricate threaded parts with an appropriate lubricant when reassembling.
