Composition / Information on Ingredients

Chemical Components:
Vinyl acetate polymer: 45-65%
Ethylene polymer: 2-10%
Water: 30-55%
Residual monomers (vinyl acetate): less than 1%
Additives and stabilizers: proprietary, generally less than 2%

First Aid Measures

Skin Contact: Remove contaminated clothing, rinse skin with plenty of water, wash with soap
Eye Contact: Rinse cautiously with water for several minutes; remove contact lenses if present; seek medical attention if irritation persists
Inhalation: Move person to fresh air, support breathing as necessary, get attention if symptoms like headache or dizziness occur
Ingestion: Do not induce vomiting; rinse mouth with water; seek immediate medical attention
Note for Physicians: Treat symptomatically; no specific antidote known

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Unsuitable Extinguishing Media: Direct water jets may spread spilled material
Hazards from Combustion: Can release carbon monoxide, carbon dioxide, low levels of acetic acid, and other volatile organic compounds under high heat
Protective Equipment for Firefighters: Self-contained breathing apparatus, protective suit
Other Considerations: Prevent contaminated fire runoff from entering drains or watercourses

Accidental Release Measures

Personal Precautions: Wear gloves, goggles, long-sleeved clothing; ventilate area
Environmental Precautions: Prevent entry into sewers, surface water, or soil
Cleanup Methods: Absorb with inert material (sand, earth); collect in sealed containers; wash residues with water and detergent
Disposal: Place absorbents and washings in approved waste containers; follow local waste regulations
Spill Risk: Risk of slip and fall from residue, cordon off area if needed

Handling and Storage

Safe Handling Recommendations: Avoid consistent skin contact or inhalation of vapor/mist; wash hands after use; do not eat or drink while working
Storage Conditions: Store in tightly closed containers out of direct sunlight; keep at temperatures above 4°C and below 30°C to prevent freezing or degradation
Incompatible Products: Strong oxidizers, acids, and alkalis can destabilize the emulsion
Special Storage Advice: Rotate inventory to avoid long-term aging; label all containers clearly, keep raw and finished products separated

Exposure Controls and Personal Protection

Engineering Controls: Use good local exhaust ventilation in areas with heavy use or limited airflow
Occupational Exposure Limits: No established threshold limit values for finished emulsion; monitor for vinyl acetate vapor (limit varies by region; generally 10 ppm ACGIH TLV)
Personal Protection: Safety goggles, chemical-resistant gloves, protective clothing
Respiratory Protection: Not typically required for routine use; wear approved mask if working with mist or heated product
Hygiene Measures: Wash thoroughly after handling; no smoking or eating in work area; shower after shift

Physical and Chemical Properties

Appearance: White to off-white milky liquid
Odor: Slight, mild, may smell faintly like vinegar
pH: 4.5 – 6.5
Melting Point / Freezing Point: 0°C (emulsion freezes)
Boiling Point: Approximately 100°C (water component)
Flash Point: Not applicable (water-based, non-flammable)
Evaporation Rate: Similar to water
Vapor Pressure: Comparable to water, low at ambient temperatures
Solubility: Miscible in water
Density: About 1.05 g/cm³
Viscosity: 500–3500 mPa.s depending on grade and manufacturer

Stability and Reactivity

Chemical Stability: Stable under normal storage and use conditions
Possibility of Hazardous Reactions: No dangerous reactions under recommended use
Conditions to Avoid: Extreme temperatures, freezing, direct sunlight, strong acids or alkalies
Incompatible Materials: Avoid mixing with strong oxidizing agents, strong acids, strong bases
Decomposition Products: Combustion or excessive heat can break down polymer, forming acetic acid, carbon monoxide, and carbon dioxide

Toxicological Information

Acute Toxicity: Low risk under typical use; LD50 (oral, rat) above 2000 mg/kg
Health Effects: Possible mild irritation to skin, eyes, airway; not linked to sensitization or chronic toxicity; no known carcinogenicity
Inhalation: Short-term exposure can cause headache, drowsiness with high vapor concentrations but not common
Skin/Eye Contact: Irritation, redness; washing with water usually relieves symptoms
Chronic Exposure: No systemic toxicity observed with repeated dermal or inhalation exposure based on available animal studies
Additional Data: No mutagenicity or reproductive toxicity found in standard testing

Ecological Information

Aquatic Toxicity: Non-toxic to aquatic life at typical concentrations but avoid large releases
Persistence and Degradability: Polymeric material breaks down gradually in the environment; auxiliary chemicals and emulsifiers may degrade more rapidly
Bioaccumulation Potential: Not expected to accumulate in living organisms
Soil Mobility: Emulsion disperses freely in water, may be washed through soil by rainwater
Other Environmental Info: Residual vinyl acetate monomer degrades quickly, limiting environmental risk

Disposal Considerations

Waste Disposal Methods: Dispose of in accordance with local and national regulations; non-hazardous landfill or incineration at proper facility, based on local guidance
Container Disposal: Rinse containers thoroughly, recycle or dispose of as per legislation
Precautions for Disposal: Prevent liquid residue from entering watercourses, sewer systems, storm drains
Special Waste Handling: Large quantities may have special requirements—consult local environmental contractor for recommendations
