Packaging and shipping
Propylene glycol monopropyl ether (DPhP) is a high-performance solvent that introduces a propyl chain onto the glycol ether framework. This structure endows it with unique advantages that distinguish it from other alcohol ether solvents: a higher boiling point, significant hydrophobicity, excellent permeation and coupling capabilities, and extremely low evaporation rate. It is a key functional material for addressing challenges related to hydrophobic compatibility, long-lasting effects, and deep penetration in high-end formulations, and is particularly suitable for industrial fields with stringent performance requirements.substances, can effectively dissolve resins, oils, etc., and is an excellent coupling agent and emulsifier, significantly improving the compatibility of multi-component systems.
Balanced volatility and leveling performance: Its volatility rate lies between fast-drying and slow-drying solvents, ensuring construction efficiency while effectively avoiding paint film defects (such as orange peel and pinholes) caused by rapid evaporation, providing excellent leveling properties.
Excellent wetting and penetration: It has a low surface tension, significantly reducing the surface tension of the system, enhancing the wetting and penetration of the substrate, and improving product adhesion and performance.

Product Core Positioning
Di-pentyl glycol monopropyl ether (DPhP) is a high-performance solvent that introduces a propyl chain onto the glycol ether framework. This structure endows it with unique advantages that distinguish it from other alcohol ether solvents: a higher boiling point, significant hydrophobicity, excellent permeation and coupling capabilities, as well as extremely low evaporation rate. It is a key functional material for addressing challenges such as hydrophobic compatibility, long-lasting effects, and deep penetration in high-end formulations, and is particularly suitable for industrial fields with stringent performance requirements.
High-end industrial coatings and resins: As efficient high-boiling-point hydrophobic regulators and slow-drying solvents, DPhP can significantly optimize the leveling process of coatings, eliminate surface defects, and effectively enhance the water resistance, chemical resistance, and early water resistance of the paint film. It is widely used in automotive original paint, industrial protective coatings, plastic coatings, and high-performance resin systems.
Powerful industrial cleaning and degreasing: With its strong dissolving power for stubborn hydrophobic dirt such as mineral oil, lubricating grease, and polishing wax, as well as the long-lasting contact and penetration time brought by high boiling points, it is a key component for preparing heavy oil cleaning agents, mold cleaning agents, engine degreasing agents, and heating cleaning formulas. The cleaning efficiency is far superior to conventional solvents.
Agricultural chemical enhancers: As a highly effective penetrant and enhancer solvent, it can significantly improve the wetting, spreading, and internal absorption and conduction efficiency of the liquid medicine on plant leaf surfaces and pest skins, thereby significantly enhancing the efficacy of herbicides, insecticides, etc., and helping customers achieve the environmental protection goal of reduced dosage and increased efficiency.
Daily chemical products and personal care: In the formulation, it plays the role of an efficient coupling agent and moisturizer, which can stabilize and enhance the solubility of fragrances, vegetable oils, sunscreens, etc., hydrophobic active ingredients. It improves the stability of the system and gives products a refreshing and soft, outstanding skin sensation. It is often used in high-end skin care products and cosmetics.
Special chemical synthesis: Its high boiling point, low volatility, and good chemical stability make it a valuable functional solvent or reaction medium in fields such as special inks, dyes, and polymer material synthesis.
