Delta-valerolactone Green Solvent

Delta-Valerolactone is a high purity bio-based cyclic ester derived from non-food grade renewable biomass, especially corn cobs. It is a transparent to light yellow liquid with the molecular formula C₅H₈O₂, produced through advanced green fermentation technology and purification processes, with a purity of ≥99.5%, which not only meets the requirements of high performance, but also meets the trend of sustainable development of the industry.

Not only are these cyclic esters biodegradable, but their low toxicity and excellent solvency properties make them suitable for a wide range of industrial applications. Whether used in coatings and adhesive systems or as a replacement for traditional petrochemical solvents in speciality formulations, Delta-Valerolactone is becoming the industry's preferred choice for its 'performance and environmental friendliness'.

It is worth emphasising that Delta-Valerolactone leaves virtually no harmful residues during use, a feature that not only naturally fits the core principle of green chemistry, but also provides higher environmental protection for downstream enterprises in practical applications. This feature not only naturally fits the core principle of green chemistry, but also provides a higher level of environmental protection for downstream enterprises in practical applications. It can effectively reduce environmental risks while guaranteeing stable product performance and output, and help enterprises achieve production compliance with greater peace of mind.

Structural Formula

(Solvent Innovation from Agricultural Waste)

• Green Solvent for Industrial Applications

Due to its own low volatility and high solubility, Delta Valerolactone can efficiently function with a broad array of polymers, resins and actives, thus making Delta Valerolactone specifically ideal as a component for coatings, inks, industrial cleaning systems as well as adhesives. The emulsion boasts superior miscibility with conventional solvents like toluene or NMP but vastly minimizes health hazards as well as environmental pressures while being managed.

• Eco-Friendly Replacement in Coatings

As a lower-VOC replacement for petroleum solvents, it helps to develop low-VOC, water-borne, and hybrid solvent systems. Delta Valerolactone enhances flow, leveling, and film formation of automotive, wood, and industrial coatings.

• Solvent Base in Reactive Formulations

Because of its cyclic structure and functional ester functionality, Delta Valerolactone is also used as a reactive diluent as well as co-sol for special purpose formulations. With Delta Valerolactone, producers are able to achieve equilibrium between reactivity and solubility to accommodate complex systems such as UV-curable inks as well as crosslinked resins.

• Cleaner for Electronic and Specialty Surfaces

Its solvency performance and low odor profile make it an ideal component in green cleaning solutions, especially in electronic part maintenance and surface preparation where low toxicity is a priority.

• High-performance solvent systems (inks, coatings, cleaners)
• Reactive diluent in UV-curable and thermoset resin systems
• Water-based or low-VOC coating additives
• Solvent for adhesives and plasticizers
• Eco-friendly replacement for petrochemical solvents
• Industrial degreasers and surface treatment liquids

Standard packaging includes 200kg drums and ISO tank containers for bulk shipments. Custom packaging options are available based on specific client needs and regional logistics.

Delta Valerolactone offers a sustainable, non-toxic and high-performance alternative to traditional solvent chemicals as a new green solvent in downstream applications such as coatings, cleaning, inks and resin applications - an innovative chemical solution that is at the forefront of solvent innovation and fully meets the needs of emerging industries for low Volatile Organic Compound (VOC), biodegradable and non-toxic formulations.
