1. Product Introduction & Main Application
Arnico’s Mixed Xylene is a clear, powerful aromatic solvent composed of a blend of three isomers—ortho, meta, and para-xylene—along with ethylbenzene. This industrial solvent, with its high solvency power (Kb Value ≈ 98), acts as the primary thinner in the formulation of industrial and architectural paints, a metal cleaning agent, and a vital raw material in the production of plastic plasticizers (phthalates) and polyester fibers (PTA/DMT).

3. Features & Benefits
-
High Solvency Power: Provides complete and rapid dissolution of alkyd, epoxy, acrylic, and polyurethane resins without causing turbidity.
-
Balanced Evaporation Rate: Its suitable evaporation speed prevents premature drying during paint spraying while keeping the final drying time reasonable.
-
Exceptional Purity (Isomerization Grade): Very low sulfur and olefin content prevents poisoning of expensive platinum catalysts in petrochemical units.
-
Clean & Low-Odor Solvent: An ideal replacement for heavier petroleum solvents, creating a smooth, spot-free final surface.
4. Industrial Applications
-
Paint & Coatings Industry: The primary thinner for fast-drying thinners, baking enamels, and industrial spray paints.
-
Petrochemical Industry: The feedstock for paraxylene units to produce PTA and PET bottles.
-
Adhesive Manufacturing: A solvent in the production of contact adhesives for shoes and furniture.
-
Printing & Packaging Industry: A flexographic ink solvent and a plate cleaner.
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): This liquid is flammable and toxic. Its vapors are heavier than air, and prolonged inhalation causes dizziness and liver damage. The Arnico MSDS file must be obtained.
-
Storage Conditions: Store in fixed-roof tanks equipped with a breather valve and earthing, in a cool environment, away from sparks and heat.
-
Personal Protective Equipment (PPE): The use of a respirator with an AX filter, Viton gloves, and anti-static clothing is mandatory.
6. Quality Assurance & COA
Arnico Mixed Xylene shipments are supplied with a Certificate of Analysis (COA) detailing a GC analysis of isomers and the flash point.
