Naphta Solvent 100 ( Kokosal)
Naphta Solvent 100, commonly known as Kokosal, is a petroleum-derived hydrocarbon solvent composed primarily of aliphatic and aromatic hydrocarbons with a boiling range near 100°C. It is a clear, colorless to pale yellow liquid with a characteristic hydrocarbon odor. Kokosal is widely used as an industrial solvent due to its excellent solvency power, moderate evaporation rate, and compatibility with many resins, oils, and waxes. It is valued in applications such as coatings, adhesives, cleaning, and chemical synthesis.
Primary UsesÂ
- Industrial Cleaning Solvent
- Used for degreasing and cleaning machinery, metal parts, and electronic components.

- Paints and Coatings
- Serves as a solvent and diluent in paints, varnishes, and lacquers.
- Enhances flow, leveling, and drying properties of coatings.
- Adhesives and Sealants
- Used as a carrier solvent in formulations of adhesives, sealants, and rubber cements.
- Provides suitable viscosity and drying characteristics.
- Chemical Intermediate and Extraction Solvent
- Employed as a solvent in chemical synthesis and extraction processes.
- Useful in refining or purification of oils and other organic compounds.
Secondary UsesÂ
- Printing Inks
- Used as a solvent in solvent-based printing inks for flexibility and gloss enhancement.
- Pharmaceutical and Cosmetic Industries
- Occasionally used as a processing solvent for certain raw materials and intermediates (not for direct product use).
- Rubber and Tire Industry
- Used in rubber processing for cleaning and as a solvent carrier for additives.
- Fuel Additive
- Sometimes blended in small quantities as a fuel additive to improve combustion characteristics.
- Agricultural Chemicals
Used as a solvent in formulation of pesticides and herbicides for effective application.
