Propylene Glycol Monobutyl Ether (BPPG-500) - Product Overview

BPPG-500, also known as Propylene Glycol Monobutyl Ether (PGBE) or 1-Butoxy-2-propanol, is a high-performance industrial solvent and coalescent agent. Renowned for its excellent solvency, low volatility, and low toxicity, it balances hydrophilic and lipophilic properties to dissolve resins, polymers, and organic compounds effectively. Compliant with environmental standards, it features low odor and biodegradability, ensuring safe use in various applications. Ideal as a coalescent for water-based coatings, solvent for inks/adhesives, and additive for industrial cleaners, BPPG-500 enhances product stability, film-forming quality, and cleaning efficiency. Factory-supplied with consistent quality, it meets the rigorous demands of coating, printing, and industrial manufacturing sectors.


Product Advantage

  1. Excellent Solvency & Compatibility

    It dissolves most organic solvents and partially mixes with water, effectively emulsifying oils/stains—ideal for multi-component formulations. Its hydroxyl value (102-122 mgKOH/g) ensures stable performance in diverse systems.

  2. Low Volatility & Eco-Friendliness

    With low VOC emissions, it meets environmental protection standards (suitable for low-VOC systems), reducing air pollution risks while maintaining long-lasting efficacy in applications like coatings.

  3. Broad pH Adaptability

    Stable within pH 5.0-7.0, it performs consistently in neutral/weakly acidic formulations (e.g., cleaners, coatings), avoiding degradation or performance loss.

  4. Multi-Functional Performance

    Acts as a solvent, emulsifier, and coalescent agent simultaneously, simplifying formulation processes and cutting production costs for manufacturers.

Product Uses

  1. Household & Industrial Cleaners

    Used as a solvent/emulsifier in kitchen, floor, and metal cleaners—it quickly dissolves grease, oil, and stubborn stains, leaving surfaces residue-free.

  2. Coatings & Inks

    Serves as a coalescent agent in water-based latex paints and ink formulations, enhancing film formation and improving coating adhesion/leveling.

  3. Textile & Printing Applications

    Acts as a solvent in textile auxiliaries and printing inks, ensuring uniform dye dispersion and stable product performance.


Product Operate Guide

For cleaners: Add 5-15% BPPG-500 to the formulation, stir evenly (200-300 rpm) for 5-10 minutes at room temperature. For coatings: Mix 3-8% with resin/emulsions, then blend with other components—avoid high-temperature (>60℃) stirring to preserve stability.


FAQ

  1. Is BPPG-500 safe for low-VOC systems?

    Yes. It has low VOC emissions and complies with environmental standards, making it suitable for low-VOC coatings, cleaners, and other eco-friendly formulations.

  2. Can BPPG-500 mix with water?

    It partially dissolves in water (compatible with most aqueous systems) and fully mixes with organic solvents, adapting to both water-based and solvent-based formulations.

  3. What's the recommended storage condition?

    Store in a cool, dry, ventilated area (10-30℃) away from direct sunlight. Seal tightly after use to prevent moisture absorption and maintain product stability.
