Important Acid Catalyst Information

The PD2K MC3000 and MC4000 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 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.
