Copper Naphthenate: 6-18%
Naphthenic Acids (various): 30-70%
Hydrocarbon solvent (carrier): Balance (often mineral spirits or kerosene)
Impurities: Trace amounts of heavy metals, unreacted acids
Other: Proprietary performance enhancers may be present according to producer
Eye Contact: Flush eyes immediately with large amounts of water for at least 15 minutes, remove contacts if present, seek medical attention if irritation persists
Skin Contact: Remove soiled clothing, wash skin with soap and water, consult physician for rash or prolonged redness
Inhalation: Move to fresh air, provide artificial respiration if breathing stops, seek medical help for coughing, headaches, or dizziness
Ingestion: Do not induce vomiting, rinse mouth, give water only as advised by a medical professional, consult poison control or see doctor right away
Suitable Extinguishing Media: Carbon dioxide, dry chemical, foam or water fog
Special Hazards: Emits toxic copper fumes and hydrocarbons during combustion, risk of explosion from vapors in closed spaces, residue may be slippery
Protective Equipment: Firefighters must use self-contained breathing apparatus and full protective gear
Fire-Fighting Instructions: Keep containers cool with water spray, dike run-off to prevent environmental contamination, address small fires with dry media, avoid breathing smoke or vapor
Personal Precaution: Wear chemical-resistant gloves, goggles, and protective clothing, avoid skin or eye contact
Methods for Cleanup: Contain spill with absorbents like inert clay or sand, prevent runoff into drains and waterways, collect residues with non-sparking tools, store waste in proper chemical containers for disposal
Environmental Precaution: Block entry to sewers and water sources, contact regulatory authorities immediately for large spills
Handling Practices: Maintain good ventilation, avoid any contact with skin or eyes, do not eat or drink while using, remove contaminated clothing soon after exposure, wash hands frequently
Storage Requirements: Keep container tightly closed when not in use, store in cool, dry and well-ventilated space away from acids, oxidizers, and open flames, label area appropriately, keep away from food and animal feedstocks
Incompatibilities: Do not mix with strong acids, alkalis, or oxidants; avoid heat and moisture
Exposure Limits: ACGIH TLV for copper dust/mist: 1 mg/m³ (as Cu), but formulation may vary
Engineering Controls: Use local exhaust ventilation and process enclosure if possible, ensure eyewash stations are available
Personal Protective Equipment: Chemical-resistant gloves (nitrile, neoprene), long sleeves, chemical goggles or face shields, rubber boots, use NIOSH-approved respirator in poorly ventilated or spray application settings
Hygiene Recommendations: Shower after use, launder soiled work clothing before reuse
Appearance: Dark green to blue liquid
Odor: Petroleum or solvent-like
Melting Point: Not applicable (liquid at room temperature)
Boiling Point: 150-300°C (varies by solvent base)
Flash Point: 38-60°C / 100-140°F (dependent on solvent base)
Solubility in Water: Insoluble
Vapor Pressure: Low at 20°C
Specific Gravity: Range 0.85-1.10
Other Properties: Forms emulsions in water, stable under standard conditions, pH typically acidic
Chemical Stability: Stable under normal use and storage conditions
Conditions to Avoid: Sources of heat, sparks, or open flames, contamination with incompatible materials like strong acids or oxidizers
Hazardous Decomposition: Produces copper oxides, carbon oxides, potentially toxic hydrocarbons and naphthenic acid fumes during thermal breakdown or fire
Polymerization: Does not occur under typical conditions
Acute Effects: Oral and dermal exposures can cause primary skin and eye irritation, respiratory issues, weakness, gastrointestinal upset if ingested
Chronic Effects: Long-term exposure may lead to copper accumulation, risk of liver or kidney strain, sensitization or eczema from skin contact, possible reproductive effects in high-dose exposures
Carcinogenicity: Copper salts are not considered carcinogenic, but petroleum solvents may contain mutagenic impurities
Other Health Risks: fumes from burning product are hazardous, risk increases for those with pre-existing allergies or respiratory illnesses
Aquatic Toxicity: Highly toxic to fish and aquatic organisms due to copper content, persistent and bioaccumulative in waterways, has long-term adverse effects
Environmental Fate: Copper compounds do not degrade rapidly and may migrate in soil/sediments, can build up in plants and animals
Other Impacts: Contaminates drinking water sources if not contained, persistent in ecosystems, difficult to remove once in environment
Waste Treatment Methods: Do not pour into drains, water bodies, or soil, send liquid residues to licensed hazardous waste disposal, absorb up spills with dry earth and place in chemical waste drums
Packaging Disposal: Empty containers may retain product residue, puncture or crush for recycling only if thoroughly decontaminated, follow local and regional requirements for incineration or landfill
Do Not: Burn except in facility with proper controls, avoid mixing with other waste streams
