PME(Propynol ethoxylate)

Propynol Ethoxylate (PME) is a non-ionic, ethoxylated derivative of 2-propyn-1-ol, designed to serve as an effective wetting agent, surface modifier, and flow control additive in a wide range of industrial applications. With excellent surface activity and compatibility, PME plays a critical role in enhancing formulation stability and improving surface interactions in coatings, inks, and chemical processes.

One of PME's key advantages is its ability to lower surface tension significantly, allowing for superior wetting on low-energy surfaces such as plastics, metals, and glass. It helps reduce surface defects such as cratering, pinholes, and orange peel, improving the overall appearance and performance of coatings and finishes.

In the paint and coatings industry, PME is widely used as a flow and leveling agent, contributing to uniform film formation, improved substrate wetting, and enhanced gloss. It also helps disperse pigments more evenly, aiding in color consistency and stability over time.

In agrochemical formulations, PME acts as an adjuvant to improve the spreading and adhesion of pesticides and herbicides on plant surfaces. Its surface activity enhances the bioavailability and efficacy of active ingredients.

PME is also valuable in metalworking fluids, textile auxiliaries, and cleaning formulations, where its excellent wetting and emulsification properties improve penetration and rinseability.
