Solvent 402 and White Spirit are petroleum based hydrocarbon solvents used to thin coatings, clean metal parts, and dissolve oils, greases, and resins. They matter because they balance strong solvency with controlled evaporation, which improves finish quality, cleaning speed, and workplace efficiency. Manufacturers, contractors, and maintenance teams choose them for paints, coatings, adhesives, degreasing, and fuel related applications where consistency and reliability count.
Solvent 402 and White Spirit belong to the aliphatic hydrocarbon solvent family. They share similar performance profiles, yet each fits specific process needs.
Solvent 402 delivers controlled evaporation and stable solvency for industrial formulations. Therefore, it works well in paint thinning, resin dilution, and surface preparation.
White Spirit (also known as mineral spirits) offers excellent oil and grease removal with a moderate odor and predictable drying behavior. it effectively supports maintenance, coating, and cleaning tasks across many industries. For this reason, operators rely on it when consistent performance and easy handling matter.
At the same time, because both solvents come from refined petroleum streams, suppliers carefully control their boiling range and aromatic content. Consequently, they meet specific application demands while also satisfying safety and regulatory requirements.
Industries select these solvents for practical reasons. First, they dissolve non polar contaminants efficiently. Second, they evaporate evenly, which prevents surface defects. Third, they support consistent batch to batch performance.
Key benefits include:
Strong solvency for oils, waxes, and resins
Stable evaporation for smooth finishes
Good material compatibility with common coatings
Easy handling and bulk availability
Therefore, procurement teams rely on them for repeatable results and predictable costs.
Solvent 402 and White Spirit thin alkyd paints, primers, and industrial coatings. They improve flow, leveling, and brushability. Consequently, applicators achieve uniform films without streaks.
Maintenance crews use White Spirit to clean tools, engines, and metal parts. It removes grease without aggressive attack on substrates. Likewise, Solvent 402 supports pre coating surface preparation.
Formulators add these solvents to control viscosity and open time. As a result, adhesive spreading becomes easier, and bonding quality improves.
In specific blends, these solvents act as carriers or cleaning agents. They help dissolve residues and maintain system cleanliness.
Although performance overlaps, buyers often compare these products before ordering.
| Aspect | Solvent 402 | White Spirit |
|---|---|---|
| Solvency strength | Medium–High | Medium |
| Evaporation rate | Controlled | Moderate |
| Odor level | Low–Moderate | Moderate |
| Common uses | Paints, resins, prep | Cleaning, thinning |
| Industry focus | Manufacturing | Maintenance & coating |
This comparison helps buyers match the solvent to process requirements.
The following table shows common technical ranges. Exact values depend on grade and refinery cut.
| Property | Solvent 402 | White Spirit |
|---|---|---|
| Appearance | Clear liquid | Clear liquid |
| Density @ 20 °C | 0.75–0.80 g/cm³ | 0.77–0.82 g/cm³ |
| Boiling range | 150–200 °C | 150–220 °C |
| Flash point (closed cup) | ≥38 °C | ≥38 °C |
| Aromatic content | Low | Low |
| Sulfur content | Trace | Trace |
Manufacturers test each batch to confirm compliance with declared specifications.
Producers align these solvents with recognized standards where applicable. Typical references include:
ASTM D235 for mineral spirits
ISO guidelines for petroleum solvents
EN standards for hydrocarbon fractions
In addition, suppliers provide Safety Data Sheets and Certificates of Analysis to support regulatory compliance and safe handling.
Quality control protects downstream performance. Suppliers test density, distillation range, flash point, and purity before release. Because of this, buyers receive consistent solvent behavior in every shipment.
Reputable exporters also monitor packaging integrity and contamination risks during loading and transport.
Buyers can source Solvent 402 and White Spirit in flexible packaging to suit logistics and storage plans.
Common options include:
Steel drums (160–220 kg)
IBC tanks (1,000 L)
Bulk tanker or ISO tank
Basekim supplies these solvents for regional and international markets with export ready documentation and stable lead times. Basekim also supports bulk buyers with tailored packaging and shipment planning.
Safe handling protects people and product quality. Always store these solvents in sealed containers away from ignition sources. Use proper ventilation during application. Operators should wear gloves and eye protection to prevent contact.
Because these are flammable liquids, facilities should follow local fire and safety codes during storage and transfer.
Smart purchasing starts with clear specifications. Buyers should confirm:
Required boiling range and flash point
Aromatic content limits
Packaging and delivery schedule
Documentation needs for import
When buyers align specs with application needs, they reduce waste and improve performance.
Solvent 402 and White Spirit remain essential tools for coatings, cleaning, and industrial processes. When buyers select the right grade, verify specifications, and plan logistics carefully, these solvents deliver reliable performance and strong value across applications.
Solvent 402 is mainly used for paint thinning, resin dilution, and industrial surface preparation. Because it offers controlled evaporation and stable solvency, manufacturers rely on it to improve coating flow, leveling, and application consistency in production environments.
White Spirit is widely used for cleaning, degreasing, and thinning oil-based paints. In particular, maintenance teams choose it to remove grease, oil, and residues from tools, machinery, and metal surfaces without damaging substrates.
Yes, White Spirit and mineral spirits refer to the same type of petroleum-derived hydrocarbon solvent. However, grades may vary based on boiling range, odor level, and aromatic content, so buyers should always check technical specifications before purchase.
Although both solvents come from refined petroleum streams, they serve slightly different needs. Solvent 402 focuses on controlled evaporation and formulation stability, while White Spirit emphasizes cleaning efficiency and practical on-site use. Therefore, paint manufacturers often prefer Solvent 402, whereas contractors and maintenance crews commonly select White Spirit.
