Impurities: Trace amounts of dissolved inhibitors (for storage stability), residual monomers below 1%
Other Components: Small amounts of stabilizers or polymerization inhibitors (such as MEHQ or BHT) often included to prevent unwanted reactions during transport and storage
Inhalation: Move individual to fresh air immediately, provide oxygen if breathing is difficult, consult physician
Skin Contact: Remove contaminated clothing, rinse affected areas with soap and water for at least 15 minutes, seek medical attention if irritation or redness persist
Eye Contact: Rinse cautiously with water for several minutes (remove contact lenses if present and easy to do), continue rinsing, seek medical attention
Ingestion: Rinse mouth, do not induce vomiting, give water to drink only if individual is alert, contact poison control center or physician right away
Notes to Physician: Treat symptomatically, monitor for allergic reactions or irritation, provide supportive care as necessary
Suitable Extinguishing Media: Use alcohol-resistant foam, dry chemical powder, or carbon dioxide; water spray can cool containers but will not extinguish burning liquid
Specific Hazards: Vapors may form explosive mixtures with air, combustion forms hazardous gases including carbon monoxide, carbon dioxide, and potentially acrid smoke
Protective Equipment: Firefighters require self-contained breathing apparatus (SCBA) and full protective clothing
Special Instructions: Move containers far from fire area if safe to do, cool with water to prevent overheating and rupture, avoid breathing smoke and fumes, dike runoff to prevent environmental damage
Personal Precautions: Ventilate the area, avoid spill inhalation, wear nitrile gloves, safety goggles, and chemical-resistant aprons
Environmental Precautions: Prevent product from entering drains, watercourses, and soil
Cleanup Method: Absorb spill using inert material like sand or vermiculite, scoop into appropriate containers for disposal, clean area thoroughly with soap and water, use explosion-proof equipment if spill occurs in a large quantity
Disposal: Follow local, state, and federal regulations for hazardous chemical disposal; do not flush to sewer
Handling: Use only with adequate ventilation, avoid all contact with skin, eyes, and clothing, keep containers sealed when not in use, ground and bond container when transferring
Hygiene Measures: Wash hands thoroughly after handling materials, remove contaminated protective equipment before entering public areas
Storage: Store in a cool, dry, well-ventilated place, keep away from heat, sparks, open flames, and direct sunlight, container material should resist attack from acrylate esters, usually high-density polyethylene or steel lined with suitable polymers
Incompatibilities: Avoid storage near oxidizing agents, acids, and bases which could trigger polymerization
Storage Temperature: Do not freeze, avoid temperatures above 30°C for long periods
Exposure Limits: No OSHA PEL or ACGIH TLV specific to Tripropylene Glycol Diacrylate; handle as an irritant and sensitizer
Engineering Controls: Use local exhaust or process enclosure to control airborne concentrations; fume hoods or laboratory-grade ventilation strongly recommended
Personal Protection: Safety goggles or chemical splash shields, nitrile or butyl rubber gloves, chemical-resistant apron or full suits for large-scale handling, avoid skin exposure
Respiratory Protection: Use NIOSH/MSHA approved respirators for organic vapors when working in confined or inadequately ventilated spaces
Environmental Controls: Avoid release to the environment, regular monitoring of air and water discharge from facilities using TPGDA
Appearance: Clear, colorless to pale yellow liquid
Odor: Mild, acrylate-like
Odor Threshold: Not established

Flammability: Not highly flammable, produces flammable vapors at elevated temperatures
Vapor Pressure: Less than 0.01 mmHg at 20°C
Specific Gravity: 1.02–1.06 g/cm³
Solubility: Immiscible with water; soluble in most organic solvents

Decomposition Temperature: Above 230°C
Viscosity: Moderate, 20–70 mPa·s at 25°C
Chemical Stability: Stable at room temperature under normal use and storage conditions, contains stabilizer to inhibit polymerization
Possible Hazards: Polymerizes exothermically upon contact with heat, peroxides, UV light, acids, or free radical initiators
Incompatible Materials: Strong oxidizing agents, acids, alkalis, free radical initiators
Hazardous Decomposition: Degrades into acrid smoke, carbon oxides, and potentially small quantities of toxic polymers upon combustion or strong heat
Polymerization: May occur rapidly if mixed with incompatible substances or exposed to elevated heat/light, always keep containers tightly closed with inhibitor present
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Toxicity: Low oral and dermal toxicity but can cause significant irritation
Skin Effects: Causes moderate to strong irritation, prolonged or repeated contact can induce allergic dermatitis
Eye Effects: Vapors or liquid cause irritation, tearing, redness, and pain
Sensitization: Can induce skin sensitization and allergic reactions in a portion of exposed persons
Inhalation Effects: High vapor concentrations cause headache, respiratory tract irritation
Chronic Effects: Repeated exposure may cause gradual skin sensitization, dryness, and eczema; no strong evidence for mutagenicity or carcinogenicity based on available data
