Applications / Uses

• Industrial Solvent: Used as a co-solvent or plasticizer in paints, coatings, inks, and adhesives, providing excellent flow, leveling, and low volatility.
• Resin Systems: Enhances flexibility and processability in polymer and resin formulations.
• Cleaning & Degreasing: Effective in precision cleaning formulations due to balanced solvency and evaporation rate.
• Specialty Chemical Intermediates: Utilized in esterification and etherification reactions requiring mild polarity and low odor.

Safety & Handling

• Flammability: Combustible liquid; vapors may form explosive mixtures with air.
• Health Hazards:
• Inhalation: May cause mild respiratory irritation or CNS effects at high concentrations.
• Skin Contact: Prolonged or repeated exposure can cause irritation or dryness.
• Eye Contact: Contact may result in redness or irritation.
• Chronic Exposure: No significant reproductive or mutagenic effects observed under tested conditions.
• Precautions:
• Use only in well-ventilated areas.
• Avoid heat, sparks, and open flames.
• Wear appropriate gloves, eye/face protection, and protective clothing.
• Ground and bond containers during transfer to prevent static discharge.
• Reactivity / Incompatibilities: Avoid contact with strong oxidizing agents or strong alkalis; material may decompose under prolonged heat exposure.

Packaging & Storage

• Packaging: Supplied in sealed, solvent-compatible metal drums or IBC containers suitable for industrial bulk use.
• Storage Conditions: Store in cool (<30 °C), dry, well-ventilated area away from direct sunlight and ignition sources. Keep containers tightly closed when not in use.
• Shelf Life: Stable under recommended storage; inspect appearance and container integrity before long-term use.
