Processing Methods & Reference Formulations
A. Paint Stripper
Methylene Chloride is often used at 50–90% in paint strippers due to its excellent solvency for most paints, varnishes, and coatings. It penetrates quickly and disrupts film adhesion. Add acid scavengers or stabilizers (e.g., amines or alcohols) to prevent degradation of methylene chloride, especially when heated or stored over time.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Methylene Chloride (DCM) | 50% |
| Benzyl Alcohol | 10% |
| Methanol | 5% |
| Phenol (hydroxybenzene) | 3% |
| Fatty Acid Sulfonate (surfactant) | 5% |
| Water | 27% |
B. Paint Remover
Add 60–90% Methylene Chloride as the primary paint-softening agent due to its high solvency power for a wide range of coatings, including enamel, urethane, and epoxy-based paints. Methylene Chloride is volatile and toxic, mix it in a closed vessel with proper ventilation and temperature control (avoid heating). Use explosion-proof equipment if needed.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Methylene Chloride (DCM) | 80% |
| Acetone | 4% |
| Pyridine | 2.2% |
| Formic Acid | 2.2% |
| Ceresin Wax (hard paraffin wax) | 2.2% |
| Cellulose Acetate (thickener) | 1.6% |
| Ethanol | 1.6% |
| Phosphoric Acid | 1.6% |
| Aqueous Ammonia | 12% |
C. Adhesive Remover
Blend with co-solvents like methanol, acetone, or toluene to adjust evaporation rate, increase solvency for various adhesive types, and improve workability. DCM is volatile and hazardous, incorporate it in a closed mixing system with proper ventilation and explosion-proof handling.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Methylene Chloride | 82% |
| Lower Alkyl Alcohol (e.g., methanol) | 11% |
| Acetone (or Methyl Ethyl Ketone) | 4% |
| Thickener (as separate base) | balance |
Dosing Guidelines
A. Dosing by Application
| Products | Authorized dosage % |
|---|---|
| Paint and varnish removers | 60-90% |
| Adhesive formulations | 10-50% |
About Methylene Chloride
Methylene chloride (dichloromethane, DCM) is a powerful, fast-evaporating chlorinated solvent valued for its high solvency, non-flammability and low boiling point. It dissolves a wide range of resins, oils, fats and polymers, and is used in pharmaceutical extraction, paint stripping, adhesives, polyurethane foam blowing, metal degreasing and as a process solvent. Unusually among strong solvents, methylene chloride is effectively non-flammable, which is why it became a workhorse in paint stripping and vapour degreasing. However, it is subject to tightening regulation notably a US EPA ban on consumer paint-stripping uses so grade and permitted-use compliance for the destination market is a critical sourcing consideration. Industrial buyers sourcing Methylene Chloride (MDC) in bulk also track methylene chloride pricing closely, since it feeds directly into their downstream costs which is why working with an established methylene chloride supplier and distributor like Elchemy matters.
- High Solvency: Dissolving capability with competitive methylene chloride price
- Low Boiling Point: Enables quick evaporation and efficient processing
- Versatile Use: Suitable for multiple industrial applications
- Cost Effective: Bulk sourcing supported by optimized methylene chloride price per kg
- Reliable Supply: Easy methylene chloride buy online and global availability
