Important Acid Catalyst Information

Important Acid Catalyst Information
Only the PD2K Acid Catalyst Model Proportioners are 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.
