Common name: Ethoxylated 3 Trimethylolpropane Triacrylate JRCure 5302
Typical use: Photopolymerization in inks, coatings, adhesives
Appearance: Clear to pale yellow liquid, viscosity can feel sticky on skin, strong acrylate odor lingers on gloves and surfaces after contact.
CAS number: 28961-43-5
Hazard class: Skin irritant, eye irritant, respiratory sensitizer
Routes of exposure: Inhalation, skin contact, eye contact
Hazard statements: Causes skin irritation, can trigger allergic skin reactions, serious eye irritation possible, vapor may irritate nose and throat, accidental ingestion brings significant health risks
Pictograms: Exclamation mark often listed due to irritation potential.
Signal word: Warning, since symptoms often appear rapidly and can build each time you handle the material.
Chemical identity: Oligomeric acrylate ester
Main ingredient: Ethoxylated trimethylolpropane triacrylate, concentration usually high enough to make up nearly all the product
Impurities: Acrylate monomers, trace stabilizers, but these rarely get listed in detail on generic safety sheets.
Inhalation: Get outdoors right away if vapors cause a cough, tight chest, or dizziness; seek medical help if breathing feels labored after exposure.
Skin contact: Remove contaminated clothing, rinse exposed skin thoroughly with soap and water, avoid scrubbing too hard as this could worsen irritation; seek medical attention if redness or blistering spreads.
Eye contact: Rinse eyes with plenty of water for at least fifteen minutes, lift eyelids to clear away residues, don’t wait to see if irritation passes on its own—see a doctor.
Ingestion: Don’t induce vomiting, rinse mouth and seek urgent medical care.
Suitable extinguishing media: Dry chemical, carbon dioxide, foam; using water can work but may cause splattering and spread irritation.
Hazardous combustion products: Acrid smoke, carbon monoxide, carbon dioxide, acrylate vapors
Protective instructions: Firefighters should reach for self-contained breathing apparatus, keep upwind, avoid breathing any smoke or vapor, cool containers exposed to flames.
Spill cleanup: Ventilate area well, wear gloves, goggles, and a fitted mask if available; use absorbent material such as sand or clay to soak up the bulk, shovel waste to a sealed container.
Precautions: Avoid direct contact, use tools rather than hands, don’t wash residues directly down drains since waterways may suffer.
Environmental steps: Prevent further leakage, check for contamination of soil or drains, report larger spills to local authorities, especially if they enter public water systems.
Handling: Use in well-ventilated places, limit exposure by keeping containers closed unless pouring or mixing, always wear compatible gloves and splash-proof eye protection. Avoid eating, drinking, or smoking in work areas.
Storage: Store at moderate temperature, keep away from sunlight and heat sources, segregate from oxidizers and strong acids, make sure containers stay tightly sealed to prevent vapor build-up.
Engineering controls: Use laboratory hoods or local exhaust systems whenever possible, pay attention to air movement so vapors don’t reach face level.
Personal protective equipment: Wear chemical-resistant gloves such as nitrile, safety goggles, lab coat, closed-toe shoes, and a face shield for splash-prone tasks.
Workplace monitoring: Use monitoring badges if chronic exposure might build up; encourage regular safety reviews to lower risk of complacency.
Hygiene steps: Wash hands before leaving work area, launder contaminated clothing separately.
Physical state: Liquid, viscosity is thicker than water, may spill slowly.
Color: Clear to faint yellow
Odor: Strong, distinctive acrylate scent
Boiling point: Higher than water, but avoid heating it above 150°C
Solubility: Low solubility in water, mixes well with organic solvents
Flash point: Around 110°C or higher, so vapor burns with enough heat.
Vapor pressure: Low at room temperature, although vapors still noticeable around open containers.
Chemical stability: Stable below recommended storage temperature, but can polymerize or decompose after long exposure to heat, sunlight, or contamination with certain chemicals.
Reactive hazards: Strong acids, bases, and oxidizers can speed up dangerous reactions.
Polymerization risk: Accidental polymerization gives off heat and may create solid masses in pipes or containers, so always avoid cross-contamination.
Acute effects: Skin redness, itching, eye pain, throat irritation, nausea if swallowed; those with allergies can have more serious effects over time.
Chronic exposure: Sensitization can develop after repeated exposure, which turns minor rashes into severe allergic responses.
Animal studies: Tests on laboratory animals show significant irritation; some studies mention low oral or dermal toxicity, though caution outweighs convenience here since human data is less thorough.
Carcinogenicity: Not classed by major health agencies as carcinogenic, but limited data means caution is wise.
Medical observations: Sensitive individuals may notice coughs or persistent rash after several days’ repeated handling, especially without gloves.
Mobility: May persist in soil and water if spilled, since it degrades slowly in outdoor conditions.
Aquatic hazards: Toxic to fish and invertebrates, can cause behavioral or reproductive changes in some aquatic species at very low concentrations.
Environmental breakdown: Slow degradation through microbial action but risk of buildup in sediment and aquatic life.
Bird and mammal impact: There’s not enough field data, but animals exposed to contaminated food or water may suffer similar irritation or toxic effects.
Waste methods: Dispose as hazardous waste, use sealed containers, take to approved chemical collection site.
Don’t throw in regular trash: Landfill disposal risks leaching and long-term pollution.
Avoid drains: Because sewage systems cannot effectively remove or break down acrylate chemicals.
Containers: Rinse empty drums thoroughly, give them to certified recyclers where possible, label all waste properly.
Shipping class: Often regulated as hazardous material for road, rail, and air shipment
Packaging: Use leak-proof drums or bottles, including secondary containment for larger bulk shipments
Transport risks: Leaks create traffic and environmental safety hazards, emergency plans must be in place, and safety data sheets travel with the shipment.
Spill response: Transporters should have absorbent pads and containment barriers on hand for emergencies.
Worker protection: OSHA and local safety regulations set standards for handling and exposure
Environmental release: Chemical is subject to reporting in many countries if large spills occur
Labeling: Both workplace and consumer labels must highlight health risks and safe handling advice
Restriction: Some jurisdictions restrict uses in products reaching children or consumer skin contact, especially in toys or cosmetics.
