Product Name: 1,6-Hexanediol Diacrylate (JRCure 5201)
Chemical Formula: C14H22O4
Common Use: Used in UV-curable coatings, inks, adhesives, and sometimes dental and medical materials. This substance plays an important part in modern industrial processes that require strong, quick-setting polymers.
Hazard Class: Classified as irritating to skin and eyes, sensitizing through skin contact, and harmful if swallowed.
Possible Health Effects: Causes skin and respiratory irritation. Prolonged or repeated exposure may lead to allergic skin reactions. Strong fumes increase risks for eye discomfort, sore throat, and headaches.
Environmental Hazards: Potential to harm aquatic life with long-lasting effects. Once released, diacrylate forms can contaminate water supplies if not contained.
Chemical Identity: 1,6-Hexanediol diacrylate, CAS: 13048-33-4
Purity: Usually exceeds 95% in industrial grades.
Toxic Components: Trace stabilizers or inhibitors added to reduce unwanted polymerization. Any impurities tend to create higher reactivity and unpredictability in use or spills.
Skin Contact: Flush affected area with plenty of water and mild soap. If redness develops, discontinue exposure and get medical attention.
Eye Contact: Rinse eyes immediately with water for at least 15 minutes. Remove contact lenses if possible and seek help.
Inhalation: Remove to fresh air. If breathing is difficult, use oxygen, and seek medical attention.
Ingestion: Do not induce vomiting. Rinse mouth with water and get prompt medical care. Absorption through ingestion can lead to systemic toxicity.
Suitable Extinguishing Media: Use foam, carbon dioxide, or dry chemical powder. Water may cause material to splatter, spreading the fire rather than quenching it.
Protection for Firefighters: Wear self-contained breathing apparatus. Product can break down under heat to produce toxic vapors, such as acrylic monomers and oxides of carbon.
Special Hazards: Closed containers risk rupture from heat buildup.
Personal Protection: Put on gloves, protective goggles, and suitable respiratory gear. Avoid contact with spilled liquid.
Cleanup Procedure: Use inert absorbent to pick up the material. Place waste in sealed containers for disposal.
Environmental Precautions: Keep the substance away from drains and water sources. Prevent spilled material from entering natural soil or waterways to minimize the impact on local ecosystems.
Handling Guidelines: Work in a well-ventilated area with minimal exposure to open flames or UV light. Always wear gloves and eye protection.
Storage Recommendations: Store in cool, dry areas out of direct sunlight, in tightly sealed original packaging. Avoid strong acids, bases, and oxidizing materials to prevent unwanted reactions. Shelf-life decreases if exposed to heat or moisture.
Engineering Controls: Ventilation or local exhaust helps reduce airborne fumes. Closed systems prevent volatile loss.
Personal Protection: Nitrile gloves, long sleeves, safety goggles, and, if ventilation is inadequate, a respirator designed for organic chemicals. Wash hands thoroughly after contact.
Appearance: Clear, colorless to pale yellow liquid with an acrylic odor.
Boiling Point: Above 120°C.
Flash Point: Near 100°C (closed cup).
Solubility: Limited water solubility. It dissolves well in organic solvents such as alcohols or ketones.
Vapor Pressure: Low at room temperature. Fumes increase at higher temperatures.
Reactivity: The compound reacts vigorously with strong oxidizers and acids or bases. Can polymerize spontaneously under UV light or heat.
Chemical Stability: Stable under recommended storage conditions. Instability follows exposure to heavy metals, peroxides, or prolonged heat.
Hazardous Decomposition: In fire, breaks down into carbon monoxide, carbon dioxide, and various acrylate monomers.
Acute Toxicity: Ingestion or inhalation can cause headache, dizziness, nausea, and distress.
Local Effects: High risk for irritation and allergic reactions on exposed skin.
Long-Term Risks: Repeated exposure has been linked to allergic dermatitis and may increase sensitivity to future acrylic exposures. Studies on long-term systemic health effects remain limited, but prudent handling cuts risk.
Aquatic Toxicity: Shown to be harmful to aquatic organisms, especially in concentrated form. Bioaccumulation studies suggest limited but measurable build-up in some aquatic environments.
Persistence and Degradability: Breaks down slowly if left in the environment. Poorly handled spills can linger, disrupting plant and animal life.
Mobility: Tends to stay in soil and surface water. Not highly volatile, so airborne spread remains unlikely.
Disposal Methods: Dispose of uncured material as hazardous waste at a licensed facility. Avoid pouring into sewers or landfill without proper treatment.
Container Cleaning: Rinse containers thoroughly with compatible solvents before recycling or disposal. Any residual polymer must be chemically inert.
Legal Requirements: Must conform to regional and national waste disposal standards to limit soil and water contamination.
Shipping Information: Classified under Chemicals, N.O.S. for road and sea transport in most countries.
Packing Group: Usually assigned Group III denoting low to moderate hazard during shipment.
Transport Precautions: Keep away from direct sunlight, sparks, or open flames. Use tightly sealed and labeled containers. Avoid rough handling to prevent container leaks.
Labeling Requirements: Most regulations call for clear hazard and precautionary labels for worker safety.
Workplace Regulations: Subject to occupational limits for skin contact and inhalation. Personal protective equipment standards enforced by jurisdictional authorities.
Environmental Controls: Reporting spills or releases above legal limits is mandatory. Local laws often call for record-keeping and monitoring of handling and disposal.
