Solvent 404 (TK2060) – Technical Overview, Applications and Export Markets

Solvent 404 (TK2060)

Solvent 404 (TK2060), produced by Shiraz Oil Refining Co., is a high-quality light hydrocarbon solvent manufactured from carefully refined petroleum fractions. Designed to provide an excellent balance between solvency, evaporation rate, purity, and operational safety, it has become one of the preferred industrial solvents for manufacturers of paints, coatings, adhesives, printing inks, cleaning chemicals, and numerous petrochemical products. Its narrow boiling range, low sulfur content, excellent color, and minimal residue after evaporation make it suitable for demanding industrial processes where consistent product quality is essential.

Unlike highly volatile solvents that evaporate too rapidly or heavy solvents that leave undesirable residues, Solvent 404 offers a controlled evaporation profile that improves production efficiency while producing smooth and uniform finished products. These characteristics have made it a reliable raw material across a wide range of manufacturing industries.

Technical Data Sheet (TDS)

Understanding the Most Important Technical Properties

The distillation range is the most significant characteristic of any hydrocarbon solvent because it determines evaporation behavior during industrial use. Solvent 404 begins boiling at 95.5°C and completes distillation at 138°C, providing a controlled evaporation profile that allows coatings and adhesives to level properly before drying. This balanced boiling range reduces surface defects such as blistering, pinholes, and orange peel while minimizing solvent retention in the finished product.

The density of 754 kg/m³ classifies Solvent 404 as a light petroleum solvent. Its relatively low density facilitates pumping, blending, storage, and transportation while ensuring excellent compatibility with a broad range of hydrocarbon-based raw materials.

A specific gravity of 0.755 indicates that the solvent is lighter than water and readily separates from aqueous phases, an important advantage in industrial cleaning and solvent recovery operations.

The exceptionally low sulfur content of only 5.1 ppm is one of the product’s strongest quality indicators. Low sulfur minimizes unpleasant odor, reduces corrosion risks, improves storage stability, and contributes to cleaner manufacturing processes. It is particularly valuable in the production of premium paints, coatings, and specialty chemical products where contamination must be minimized.

The Saybolt Color of +30 demonstrates outstanding clarity and colorlessness. This property is highly desirable in white paints, clear coatings, transparent varnishes, printing inks, and light-colored chemical formulations where solvent color can affect the appearance of the final product.

The Copper Corrosion rating of Class 1a, determined according to ASTM D130, confirms that the solvent is essentially non-corrosive toward copper and copper-containing equipment. This reduces maintenance costs and extends the service life of industrial processing systems.

The Reid Vapor Pressure of 10.3 kPa provides a practical balance between volatility and handling safety. It allows efficient evaporation during manufacturing while reducing excessive vapor generation during storage and transportation.

The very low residue value of only 0.4% indicates that the solvent evaporates almost completely, leaving minimal deposits on coated surfaces or processing equipment. This characteristic is particularly important in high-quality coatings and precision cleaning applications.

Although the Doctor Test is reported as Positive, indicating the presence of trace mercaptan compounds, the measured sulfur levels remain extremely low and are generally acceptable for most industrial solvent applications.

Industrial Applications

Solvent 404 is widely used as a process solvent, thinner, cleaning agent, and formulation component across numerous manufacturing industries.

Its largest application is in the paint and coatings industry, where it serves as an effective solvent for alkyd resins, industrial enamels, protective coatings, wood finishes, and architectural paints. Its controlled evaporation rate improves flow characteristics, enhances film formation, reduces brush marks, and contributes to smoother surface finishes.

In the adhesive industry, Solvent 404 is extensively used in the production of solvent-based adhesives for footwear, furniture, packaging, woodworking, automotive components, and construction materials. The solvent helps achieve the proper viscosity while allowing sufficient working time before curing.

Manufacturers of printing inks use Solvent 404 as a formulation solvent for gravure, flexographic, and industrial printing systems. Its consistent evaporation characteristics contribute to uniform ink transfer, rapid drying, and excellent print quality.

The product also plays an important role in resin manufacturing, particularly in the production of alkyd resins and other hydrocarbon-soluble resin systems. It improves process control, facilitates mixing, and supports efficient polymer processing.

In the industrial cleaning sector, Solvent 404 effectively removes grease, lubricants, oils, waxes, and other hydrocarbon contaminants from machinery, metal parts, production equipment, and storage tanks. Its low residue ensures that cleaned surfaces remain suitable for subsequent manufacturing operations.

The rubber and tire industry employs this solvent for polymer processing, equipment cleaning, compound preparation, and viscosity adjustment during production.

Manufacturers of waxes, polishes, and maintenance chemicals utilize Solvent 404 to dissolve waxes, improve product consistency, and provide uniform application characteristics for automotive, furniture, and industrial maintenance products.

The solvent is also suitable for use in chemical blending operations, specialty formulations, degreasers, maintenance products, and numerous petroleum-based industrial chemicals requiring a high-purity hydrocarbon solvent.

Key Advantages

Solvent 404 combines a carefully controlled boiling range with excellent solvency, allowing manufacturers to achieve consistent processing performance across different production batches. Its very low sulfur content reduces odor and corrosion while improving the quality of finished products. The excellent Saybolt color ensures suitability for light-colored formulations, and its extremely low residue minimizes contamination after evaporation. Furthermore, the solvent’s low density, good storage stability, and non-corrosive nature make it easy to transport, handle, and integrate into modern industrial manufacturing systems.

Major Export Markets

The demand for Solvent 404 continues to grow across regions with well-developed paint, coating, adhesive, and chemical industries. Turkey represents one of the largest regional markets due to its extensive manufacturing base in paints, coatings, furniture, and construction chemicals. The United Arab Emirates serves both as a significant end-user and as a strategic trading hub for re-export to the Middle East and East Africa.

Pakistan imports considerable volumes of hydrocarbon solvents for its expanding paint, printing ink, adhesive, and industrial chemical sectors. Iraq remains another important destination, supported by increasing infrastructure development and demand for construction materials.

In India, one of the world’s largest chemical manufacturing economies, hydrocarbon solvents are widely consumed by the paint, coating, printing ink, resin, and adhesive industries, creating substantial opportunities for high-quality solvent suppliers.

The rapidly developing economies of Kazakhstan, Uzbekistan, Turkmenistan, and other Central Asian countries also represent promising markets, as local production capacity remains limited while industrial demand continues to increase.

Additionally, several East African countries, including Kenya, Tanzania, and Ethiopia, are experiencing sustained growth in construction, manufacturing, and industrial coatings, making them attractive long-term export destinations for petroleum solvents.
