Important Two-Component Material Information
Important Two-Component Material Information
Isocyanates (ISO) are catalysts used in two component
materials.
Isocyanate Conditions
Spraying or dispensing materials that contain
isocyanates creates potentially harmful mists,
vapors, and atomized particulates.
• Read and understand the fluid manufacturer’s
warnings and Safety Data Sheet (SDS) to know
specific hazards and precautions related to
isocyanates.
• Use of isocyanates involves potentially hazardous
procedures. Do not spray with this equipment
unless you are trained, qualified, and have read
and understood the information in this manual and
in the fluid manufacturer’s application instructions
and SDS.
• Use of incorrectly maintained or mis-adjusted
equipment may result in improperly cured
material. Equipment must be carefully maintained
and adjusted according to instructions in the
manual.
• To prevent inhalation of isocyanate 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 fluid
manufacturer’s SDS.
• Avoid all skin contact with isocyanates. Everyone
in the work area must wear chemically
impermeable gloves, protective cl oth in g an d fo ot
coverings as recommended by the fluid
manufacturer and local regulatory authority.
Follow all fluid manufacturer recommendations,
including those regarding handling of
contaminated clothing. After spraying, wash
hands and face before eating or drinking.
Material Self-ignition
Some materials may become self-igniting if applied
too thick. Read material manufacturer’s warnings and
Safety Data Sheet (SDS).
Keep Components A and B
Separate
Cross-contamination can result in cured material in
fluid lines which could cause serious injury or
damage equipment. To prevent cross-contamination:
• Never interchange component A and component
B wetted parts.
• Never use solvent on one side if it has been
contaminated from the other side.
6312799T
Important Two-Component Material Information
Moisture Sensitivity of
Isocyanates
Exposure to moisture (such as humidity) will cause ISO
to partially cure; forming small, hard, abrasive crystals,
which become suspended in the fluid. Eventually a film
will form on the surface and the ISO will begin to gel,
increasing in viscosity.
NOTICE
Partially cured ISO will reduce performance and the
life of all wetted parts.
• Always use a sealed container with a desiccant
dryer in the vent, or a nitrogen atmosphere.
Never store ISO in an open container.
• Keep the ISO pump wet cup or reservoir (if
installed) filled with appropriate lubricant. The
lubricant creates a barrier between the ISO and
the atmosphere.
• Use only moisture-proof hoses compatible with
ISO.
• Never use reclaimed solvents, which may
contain moisture. Always keep solvent
containers closed when not in use.
• Always lubricate threaded parts with an
appropriate lubricant when reassembling.
NOTE: The amount of film formation and rate of crystallization varies depending on the blend of ISO, the
humidity, and the temperature.
Changing Materials
NOTICE
Changing the material types used in your equipment
requires special attention to avoid equipment damage
and downtime.
• When changing materials, flush the equipment
multiple times to ensure it is thoroughly clean.
• Always clean the fluid inlet strainers after
flushing.
• Check with your material manufacturer for
chemical compatibility.
• When changing between epoxies and urethanes
or polyureas, disassemble and clean all fluid
components and change hoses. Epoxies often
have amines on the B (hardener) side. Polyur eas
often have aminies on the A (resin) side.

Important Acid Catalyst Information
Important Acid Catalyst Information
This pump 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 use d without substitution, to withstand the incr eased corro sive properties of these acids.
Acid Catalyst Conditions
Acid is flammable, and spraying or dispensing acid creates potentially harmful mists, vapors, and atomize d
particulates. To help prevent fire and explosion and serious injury:
• Read and understand the fluid 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 fluid 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 of Acid
Catalysts
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.
8312799T
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.
