• Key Specification Indicators: Assay (active monomer), moisture content, inhibitor level, acid value, non-volatile matter
• Storage Recommendation: Store in sealed, inhibitor-treated containers; keep under cool (<30 °C), dry, well-ventilated conditions; avoid strong oxidizers, light and heat.

Applications / Uses

• Monomer for acrylic polymers and copolymers used in coatings, adhesives, textiles, and specialty plastics.
• Used in manufacturing non-woven fibers and leather finishing resins.
• Applied in specialty chemical synthesis, such as flavor intermediates and reactive coatings.
• Suitable for processes requiring high reactivity, rapid polymerization, and acrylic ester functionality.

Safety & Handling

• Flammability: Extremely flammable liquid and vapor.
• Health Hazards:
• Inhalation: May cause respiratory irritation, dizziness, or nausea at high vapor concentrations.
• Skin Contact: Prolonged or repeated contact may cause irritation or sensitization.
• Eye Contact: May cause serious eye irritation.
• Precautions:
• Use only in well-ventilated areas or under local exhaust.
• Wear protective gloves, goggles/face shield, and appropriate protective clothing.
• Eliminate all ignition sources; ground and bond containers during transfer.
• Reactivity / Incompatibilities: Avoid strong oxidizers, peroxides, strong bases or acids; may polymerize exothermically under heat, light, or impurities.

Packaging & Storage

• Packaging: Supplied in sealed, inhibitor-treated containers suitable for monomer storage (e.g., drums or tanks).
• Storage Conditions: Store in a cool (<30 °C), dry, well-ventilated area away from heat, direct sunlight, and ignition sources; keep containers tightly closed.
• Shelf Life: Stable if stored properly; inspect for discoloration, polymerization, or container bulging before use.
