BPPG-400
Jienuo
Propylene Glycol Monobutyl Ether BPPG-400 (PGBE) is a high-performance, low-toxicity industrial solvent and coalescent agent. Boasting excellent solvency, low volatility, and water miscibility, it serves as a versatile additive for paints, coatings, inks, adhesives, and cleaning formulations. This industrial-grade product features a high boiling point and low VOC content, complying with global environmental standards like REACH. Ideal for enhancing film formation, dissolving resins, and improving product stability, BPPG-400 is widely used in automotive coatings, electronic cleaning, metalworking fluids, and textile dyeing. Its odorless, non-flammable properties ensure safe handling, making it a reliable choice for eco-friendly and high-efficiency manufacturing processes.
Product Advantage
Excellent Compatibility & Solvency
It dissolves greases, resins, and coatings effectively, while being partially water-miscible and soluble in most organic solvents. Its 5.0–7.0 neutral pH ensures stability in both acidic and basic systems, avoiding material corrosion.
Low-VOC & Eco-Friendly
Compliant with low-VOC formulation requirements, it meets environmental standards (e.g., REACH) for industrial applications. Its odorless property reduces workplace irritation, enhancing operational safety.
Stable Technical Performance
With consistent acid value (128–156 mgKOH/g) and physical properties across batches, it ensures reliable performance in long-term production, minimizing formulation variations.
Multi-Functional Utility
Acts as both a solvent and coalescent: it boosts film formation in coatings and dissolves contaminants in cleaners, reducing the need for multiple additives in formulations.

Product Uses
Cleaning Formulations
Used in household/industrial cleaners (e.g., degreasers, surface cleaners) to dissolve grease, stains, and coatings. Ideal for low-VOC cleaning systems due to its low toxicity.
Coatings & Inks
Serves as a coalescent in water-based coatings (e.g., architectural, industrial paints) to improve film integrity. Also acts as a solvent in inks, enhancing color dispersion.
Textile & Metal Processing
Works as a dyeing auxiliary in textiles to boost color penetration. In metalworking, it aids in degreasing and cleaning metal surfaces before finishing.
For cleaning formulations: Add 5–15% BPPG-400 to the mixture (adjust based on contamination level), stir evenly, and apply via spraying or wiping. For coatings: Incorporate 3–8% during the mixing stage (post-resin dispersion) to ensure uniform coalescence. Avoid contact with strong oxidizers; store in a cool, dry area.
FAQ
Is BPPG-400 compatible with water-based systems?
Yes, it is partially water-miscible and stable in 1% aqueous solutions (pH 5.0–7.0), making it suitable for water-based coatings and cleaners.
What is the storage shelf life of BPPG-400?
When stored in sealed containers (cool, dry environment), it has a shelf life of 12 months without performance degradation.
Can BPPG-400 be used in food-contact cleaning?
It is designed for industrial use; consult regulatory guidelines (e.g., FDA) before using in food-related applications.
