Description

Solvent Naphtha (Petroleum), Heavy Aliphatic is a complex hydrocarbon mixture derived from petroleum refining, characterized by its high boiling point range and predominantly aliphatic (paraffinic) structure. This product matters as a versatile, high-performance industrial solvent prized for its solvency power, controlled evaporation rate, and relatively low aromatic content, making it suitable for sensitive formulations. It is essential for manufacturers in the coatings, adhesives, rubber, and chemical processing industries who require a reliable, consistent solvent for dissolving, diluting, or extracting materials.

Application

• Coatings & Paints: Acts as a key solvent and diluent in high-solids coatings, industrial maintenance paints, and marine coatings, where its slower evaporation aids in film formation and flow.
• Adhesives & Sealants: Used as a solvent carrier in the production of rubber-based and synthetic polymer adhesives, contributing to proper viscosity and application properties.
• Rubber & Tire Manufacturing: Serves as a processing oil and solvent in the compounding and molding of rubber products, helping to disperse fillers and soften rubber compounds.
• Chemical Synthesis & Extraction: Employed as a reaction medium or extraction solvent in organic synthesis and for the purification of various chemical products.
• Industrial Cleaning & Degreasing: Formulated into heavy-duty cleaners and degreasers for machinery, engine parts, and metal surfaces due to its strong solvency for oils and greases.
• Printing Inks: Utilized as a solvent in certain specialty printing inks, particularly where a slower drying profile is required.

Quality Control

Our Solvent Naphtha (Petroleum), Heavy Aliphatic is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and performance. Key parameters such as distillation range, flash point, aromatic content, and color are rigorously monitored. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile nature, keep containers tightly sealed when not in use to prevent evaporation and maintain purity. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F).
