Products Description
Solvent-based adhesive and sealant systems use o-xylene to dissolve rubber and resin components while maintaining a workable open time before curing. GNEE BIO supplies o-xylene for this application at industrial grade, with flexible packaging from 200kg drums up to ISO tanks for larger production lines.

CAS 95-47-6 Ortho-xylene also called 1,2-dimethylbenzene, is a flammable aromatic hydrocarbon belonging to the xylene isomer family (alongside meta-xylene and para-xylene). Its chemical formula is C8H10, and it appears as a colorless liquid with a distinctive sweet aromatic scent.
In industrial settings, OX serves a dual role: as a chemical feedstock for phthalic anhydride and as a slow-evaporating solvent. Its deliberate evaporation profile makes it particularly valuable in applications requiring extended open time, such as varnishes, lacquers, industrial enamels, adhesive formulations, and sealant compounds where controlled film formation and leveling are critical.

o-xylene uses in industry
1. Adhesives & Sealants Applications:
- Solvent for rubber-based and resin-based adhesive systems
- Diluent to adjust viscosity and open time in sealant formulations
- Compatible with a range of synthetic rubber and polymer binders
- Suitable for industrial-scale adhesive production requiring consistent evaporation behavior
2. Phthalic Anhydride Production (Main Uses)
O-Xylene is a key raw material for the production of phthalic anhydride. Phthalic anhydride can be further processed into phthalate plasticizers, imparting flexibility and durability to polyvinyl chloride (PVC) products.
3. Chemical Intermediate
In the chemical industry, o-xylene is an intermediate in the production of dimethyl terephthalate (DMT), dyes, and pharmaceuticals.
4. Industrial Solvent and Diluent
Due to its slow evaporation rate, o-xylene is widely used as a solvent in the production of paints, varnishes, coatings, and finishes.
5. Adhesives and Sealants
O-xylene is an important component in various adhesive and sealant formulations.
Safety information
Orthoxylene is a highly flammable liquid and vapor. It is harmful if inhaled or absorbed through skin contact, and causes irritation to eyes, skin, and the respiratory tract. High-concentration exposure may cause dizziness, headache, nausea, and in extreme cases, respiratory failure.
- Fire prevention: Keep away from heat, sparks, and open flames. Use non-sparking tools and properly grounded containers.
- PPE: Wear safety goggles, chemical-resistant gloves, and protective clothing. Use a respirator in poorly ventilated or enclosed areas.
- Storage: Store in a cool, well-ventilated, fireproof area at 15–25°C, locked and away from incompatible materials.

FAQ
Q1: What packaging do you recommend for o-xylene supplied to adhesive manufacturers?
A: For standard adhesive production volumes, 200 kg drums are the most common choice; however, for continuous, large-scale production lines, using ISO tanks can reduce unit logistics costs.
Q2: Is your o-xylene suitable for natural rubber or synthetic rubber adhesive systems?
A: It is suitable for both. It demonstrates good compatibility with a wide range of rubber-based and resin-based adhesive formulations; please provide details of your specific polymer system so we can confirm suitability.
Q3: What quality control measures are taken before shipment?
A: Each batch undergoes testing for parameters such as purity, moisture content, color, and acidity prior to shipment to ensure consistent performance.
Q4: Can you provide a Certificate of Analysis (COA) that meets our internal quality control (QC) requirements?
A: Yes. We issue a comprehensive COA for every batch and can adjust the list of tested parameters to align with your internal QC standards.
