Dipropylene glycol butyl ether (DPNB) is a versatile industrial solvent with the following core applications and characteristics:

I. Core Solvent for Coatings and Inks

1. Film-Forming Agent for Water-Based Coatings
   • Enhances the film-forming properties of acrylic resins, epoxy resins, and other coatings, improving adhesion and wear resistance of the paint film; effectively improves viscosity stability in latex paints, preventing storage stratification or application sagging.
   • Reduces coating cracking and wrinkling issues, optimizing low-temperature application performance.
2. Ink Performance Modifier
   • Acts as a dispersant and thickener for printing inks, improving color uniformity and vibrancy; reduces viscosity to enhance printing absorption efficiency.

II. Key Component in Cleaning Agents

1. Industrial Cleaning Enhancer
   • Efficiently removes oil, grease, and stubborn stains (e.g., wax removers, paint strippers) from metal surfaces, leveraging surface activity and coupling effects.
   • Suitable for low-volatility systems (e.g., floor cleaners), extending the action time of cleaning agents.

III. Resin and Polymer Processing

1. Resin Synthesis Auxiliary Agent
   • Functions as a solvent or coagulant for polyurethane, alkyd resins, etc., participating in cross-linking reactions to form stable compounds.
2. Functional Additive
   • Improves the viscosity of adhesives and the foam stability of surfactants; enhances solubility and color fastness in the dye industry.

IV. Special Applications and Precautions

Note:

• Physical Properties: Colorless transparent liquid, density 0.97 g/cm3, boiling point 230-231°C, flash point 96°C (closed cup), slightly soluble in water (good miscibility).
• Packaging and Storage: Industrial grade (purity ≥99%), standard packaging 200kg/drum, requires light-proof and sealed storage (humidity ≤65%) to prevent oxidative degradation.
