Product Description:

Monopropylene glycol (MPG) is a versatile solvent used in paints, coatings, and inks, primarily as a coalescing agent and humectant. It helps improve paint film formation, provides freeze-thaw stability in latex paints, and can be used in alkyd resins. In inks, it acts as a solvent and can help reduce emissions during UV curing processes.

Properties:

• Appearance: Clear, colorless, and viscous liquid.
• Odor: Practically odorless.
• Solubility: Highly soluble in water, alcohols, esters, and ketones.
• Hygroscopic: Readily absorbs moisture from the air.
• Low Toxicity: Relatively low toxicity, making it suitable for various applications.
• Antifreeze: Reduces the freezing point of water, used in automotive and aircraft de-icing.
• Humectant: Attracts and retains moisture, used in personal care product

Applications:

Paints and Coatings:

Coalescing Agent: MPG facilitates the fusion of paint particles during application, resulting in a smooth, uniform, and long-lasting finish

Freeze-Thaw Stability: In latex-based paints, MPG helps prevent damage caused by freezing and thawing cycles.

Alkyd Resin Production: MPG is a key ingredient in alkyd resin manufacturing, influencing the flexibility and hardness of the final coating.

Inks:

Solvent: MPG acts as a solvent in printing inks, helping to carry the pigments and other components.

UV Curing: In UV-curable inks, MPG helps reduce emissions and lower energy consumption during the curing process.
