Precautionary Statements: Wash skin thoroughly after handling; avoid breathing dust; use only outdoors or in a well-ventilated area; wear protective gloves, clothing, and eye protection; remove contaminated clothing and wash before reuse
Main Component: Triallyl Isocyanurate (TAIC) ≥ 98%
Impurities: Contains low levels of triallyl cyanurate, residual solvents, and stabilizers; identity and concentration of impurities may vary based on manufacturing origin
Additives: Stabilizers or inhibitors to prevent unwanted crosslinking or polymerization before use; full list present on manufacturer’s specification sheets
Other Ingredients: No other hazardous substances intentionally added
Inhalation: Remove person from exposure area to fresh air immediately; ease breathing by loosening clothing; seek medical advice for persistent respiratory irritation
Skin Contact: Rinse skin thoroughly with plenty of water; use soap; remove contaminated clothing; seek attention for persistent redness, blistering, or pain
Eye Contact: Flush eyes with water for at least 15 minutes, lifting eyelids; call for prompt medical attention if irritation persists or vision blurs
Ingestion: Rinse mouth thoroughly; drink small quantities of water if conscious; avoid inducing vomiting; seek medical assessment as soon as possible
Suitable Extinguishing Media: Use foam, dry chemical powder, or carbon dioxide; avoid direct water jets that may spread product
Fire Hazards: Decomposition in fire releases hazardous gases such as nitrogen oxides and carbon oxides; product itself is combustible but not highly flammable
Special Protective Equipment: Use full protective clothing, including self-contained breathing apparatus, for all personnel fighting fire in closed spaces
Advice For Firefighters: Remove containers from fire area if safe; cool containers with water spray to prevent decomposition; do not allow contaminated runoff to enter drains or water courses
Specific Hazards: TAIC vapors heavier than air and can travel along ground to ignition source; burning material may melt and flow, spreading fire
Personal Precautions: Evacuate unnecessary personnel; wear suitable gloves, goggles, dust mask or respirator; avoid inhaling dust or vapor
Environmental Precautions: Prevent entry into sewers, storm drains, rivers or other waterways; report major spills requiring remediation to relevant authorities
Small Spills: Scoop or sweep carefully to avoid generating dust; place in sealable, labeled container for safe disposal or recovery
Large Spills: Dike spill area; use vacuum or shovel; ventilate area during cleanup; decontaminate affected surfaces with detergent and water
Disposal of Cleanup Materials: Place all contaminated materials in closed containers for disposal as chemical waste in line with local regulations
Handling Recommendations: Use only in well-ventilated settings; avoid breathing dust or vapor; always wear proper personal protective equipment
Minimize Contact: Avoid direct handling with ungloved skin; handle using tools and designated transfer systems
Storage Requirements: Store in tightly sealed containers made from compatible materials, away from sunlight, moisture, heat and sources of ignition
Temperature Control: Keep at room temperature or cooler in dry, well-ventilated spaces; avoid freezing and high temperature swings that may trigger degradation
Incompatible Materials: Store away from strong acids, bases, oxidizers, reducing agents, and polymerization initiators
Labeling: Ensure containers are labeled with hazard symbols and warnings; rotate stock and use oldest first
Occupational Exposure Limits: No national exposure limits established for TAIC, but minimize exposure in line with best practices for organic crosslinking agents
Engineering Controls: Use local exhaust ventilation to remove airborne dust or vapors; enclosure or isolation of processes preferred for high-volume usage
Personal Respiratory Protection: Use NIOSH/MSHA approved respirator for dusty or poorly ventilated settings
Hand Protection: Impermeable gloves made from nitrile or PVC; check integrity regularly
Eye and Face Protection: Tight-sealing goggles or face shield
Body Protection: Wear chemical-resistant lab coat or apron; closed-toed shoes preferred
Hygiene Measures: Wash hands before breaks, meals and after handling; no eating or drinking in processing areas
Work Practices: Use proper industrial hygiene and safety practices; provide eye wash station and emergency shower at workplace
Appearance: Colorless or white crystalline solid or flakes
Odor: Slight, organic chemical odor
Melting Point: 23-27°C (73-81°F); product softens and melts at hand warmth
Boiling Point: 174°C at 1.5 mmHg
Density: About 1.19 g/cm³ at 20°C
Solubility: Moderately soluble in organic solvents (alcohols, esters, ethers); very low solubility in water
Flash Point: >120°C (open cup)
Vapor Pressure: Low at ambient temperature
Pale Yellow Color: Purity or prolonged storage may produce a yellow tint; this does not usually indicate danger unless accompanied by odor change
Other Properties: Not strongly hygroscopic; not expected to generate static build-up if handled properly
Chemical Stability: Remains stable in unopened containers under normal temperatures and dry conditions
Hazardous Reactions: Contact with strong oxidizing agents, metals, acids or strong bases may trigger violent or hazardous reactions
Polymerization Risk: Inappropriate mixing with initiators, UV exposure, or excessive heat may trigger premature polymerization
Decomposition Products: Burning or decomposition forms gases like nitrogen dioxide, carbon monoxide and carbon dioxide
Conditions to Avoid: Prolonged heating, open flame, spark or direct sunlight
Stability Warning: Avoid storing with incompatible chemicals; inspect containers regularly for leaks or damage
Acute Toxicity: Oral LD50 (rats) over 2000 mg/kg; relatively low immediate toxicity but may provoke gastrointestinal upset
Skin Irritation: Application to skin causes redness and irritation; repeated or prolonged contact may result in dermatitis
Eye Impact: Irritating; exposure may cause watering, redness, blurred vision or pain
Sensitization: Can cause allergic skin reaction in sensitive individuals; proper PPE limits risk
Inhalation Risks: Exposure to dust or vapor irritates airways, causing coughing, wheezing or shortness of breath
Chronic Effects: No known evidence of carcinogenicity or mutagenicity; some studies report reversible changes in liver upon extended exposure at high levels
Additional Health Hazards: Overexposure without controls could worsen any pre-existing allergies or asthma in workers
Environmental Fate: TAIC breaks down slowly in soil and water; low volatility and poor water solubility restricts movement in environment
Bioaccumulation: Not expected to significantly bioaccumulate in aquatic or terrestrial organisms
Aquatic Toxicity: Moderately toxic to aquatic life; accidental emissions can damage local water ecosystems, especially at high concentrations
Soil Mobility: Likely to remain near site of release in soil or sediment; unlikely to migrate into groundwater
Persistence: Degrades over weeks to months in climate-exposed locations; decomposition rate depends greatly on temperature, humidity and microorganism activity
Other Effects: No evidence of ozone depletion or other atmospheric effects; proper disposal helps reduce chance for accidental release
Waste Characterization: Product, containers and all cleanup debris considered hazardous waste if contaminated
On-Site Disposal: Dilute, neutralize, or incinerate only after ensuring proper air pollution controls, or hand over to licensed chemical waste contractor
Do Not Dilute: Avoid flushing with large amounts of water; never release directly to surface water, drains or sewers
Container Disposal: Rinse empty containers with compatible solvent and water before delivery to hazardous recycling facilities; remove or deface original labeling
Legislation: Follow specific national, regional, and local hazardous disposal guidelines; reference relevant authorities for incident reporting and compliance
UN Number: Classified and listed under appropriate crosslinking agent or organic solid identifiers
Transport Hazard Class: Not typically regulated as hazardous for road, rail or sea under most international transport codes (ADR/RID/IMO)
