Name: Dipropylene Glycol Diacrylate (commonly called DPGDA, also referenced under trade names like JRCure 5202)
Chemical Formula: C12H18O6
CAS Number: 57472-68-1
Appearance: Colorless to pale yellow liquid with a faint, sweet odor
Common Use: Integral in inks, coatings, adhesives, UV-cured systems, and resins production
Risk Phrases: Irritates eyes, skin, and respiratory system; may trigger allergic skin reactions; possible environmental hazard for aquatic life
Potential Health Effects: Short-term exposure can cause burning or itching of eyes and skin, headache, and irritation of the throat; some cases have led to skin sensitization
Warning Symbols: Exclamation mark (acute toxicity), environment (harmful to aquatic life)
Main Ingredient: Dipropylene Glycol Diacrylate (over 95% by weight)
Impurities: Trace levels of various acrylate esters, inhibitors like hydroquinone to slow polymerization
Inhalation: Move to fresh air quickly, loosen clothing, provide oxygen if breathing trouble surfaces
Eye Contact: Rinse with plenty of water for at least 15 minutes, seek medical guidance if irritation stays
Skin Contact: Wash exposed areas with soap and water, strip off contaminated clothing, consult a physician for burns or rash
Ingestion: Rinse mouth, avoid triggering vomiting, get medical attention at once
Flammability: Decomposes at high heat, can emit irritating fumes; not extremely flammable under regular storage
Suitable Extinguishers: Carbon dioxide, dry powder, foam
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, and other harmful by-products
Special Precautions: Wear full protective gear, avoid breathing smoke or gases, keep containers cool with water spray
Personal Precautions: Suit up with chemical-resistant gloves, goggles, respirators when vapors or splashing are a concern
Spill Cleanup: Confine and soak up spills with inert material (like sand or vermiculite), shuffle into secure drums for proper disposal
Environmental Steps: Avoid dumping into drains; spills in open spaces should be blocked from waterways
Safe Handling: Work in well-ventilated zones, prevent skin and eye contact, seal containers when not in use
Storage Guidelines: Keep away from heat, direct sunlight, sparks; use grounded metal containers; store at steady temperatures below 30°C; keep away from oxidizers, acids, or bases
Keep Inhibitor Integrity: Always cap containers tightly to prevent loss of polymerization inhibitors which guard against accidental hardening
Engineering Controls: Fume hoods, local exhaust, and splash barriers help limit airborne and contact exposure
Eye Protection: Chemical safety goggles or face shields
Skin Protection: Nitrile, butyl rubber, or similar gloves; long-sleeved clothing and aprons
Respiratory Protection: Use appropriate cartridges or air-purifying respirators in higher vapor zones
Hygiene Practices: Always wash hands and exposed skin after handling tasks, change contaminated clothing without delay
Physical State: Liquid
Color: Nearly clear to pale yellow
Odor: Sweet and faint
Boiling Point: Around 230–250°C
Melting Point: Below room temperature
Vapor Pressure: Low at room temperature
Solubility: Slightly soluble in water; mixes well with most organic solvents
Density: Roughly 1.02–1.1 g/cm³
Chemical Stability: Remains stable under cool, dark, dry conditions when inhibitors are present
Reactivity: Spontaneous polymerization hazard in the absence of oxygen, heat, or with radical sources
Incompatible Materials: Strong acids, bases, oxidizers; avoid mixing with peroxides or azo compounds
Hazardous Decomposition: Produces carbon monoxide and other toxic fumes if burned or overheated
Acute Toxicity: May cause irritation to skin, eyes, and respiratory tract; animal studies flag low to moderate toxicity
Sensitization: Repeated or prolonged skin contact occasionally triggers allergic dermatitis; sensitized people might show rash or swelling after exposure
Chronic Health Risks: Limited data exists, but extended high-level exposures could stress liver or kidneys
Carcinogenicity: No current evidence of carcinogenic effects in standard animal studies or by IARC/OSHA decisions
Aquatic Toxicity: Toxic to aquatic life; spills and wash-water threaten fish and invertebrates
Persistence and Degradability: Not readily biodegradable by natural processes; may linger if released
Bioaccumulation: Little sign of building up in tissue; tends to break down in sunlight, but not quickly in water
Soil Impact: Risk of leaching down into soil, harming microorganisms or plant root systems if large quantities reach the ground
Safe Disposal: Gather waste product into sealed, labeled containers; pass along to licensed hazardous waste collectors
Incineration: Approved facilities should control emissions with effective air cleaning
Avoid: Never pour down household or public drains, dump with regular trash, or release into outside air
UN Classification: Often ships as non-dangerous when stabilized, though large bulk moves can fall under hazard class 9 (miscellaneous hazardous materials) depending on transport regulations
Packaging: Secure, leak-proof drums or tubs; keep tightly shut; check for compatible linings to prevent chemical reaction
Precautions in Transit: Prevent rough handling or overheating; avoid long stints in direct sun or near engines
Safety Mandates: Most regional work safety agencies treat DPGDA as a hazardous chemical, with specific rules for labeling, worker exposure, and emergency planning
Environmental Rules: Listings in key chemical inventories such as TSCA in the United States, REACH in Europe, and related local chemical codes
Worker Health: Use of personal protective equipment expected by labor health authorities; monitoring exposure levels recommended in manufacturing or commercial blending plants
