[Performance and characteristics]
1. This series of products are gemini non-ionic surfactants with hydrophilic, wetting, low foaming and other properties. It can reduce the surface tension of water-based system, especially the dynamic surface tension. It is applied to coatings, inks, adhesives, varnishes and other fields. For the coating film with strict requirements for surface defects, it can prevent shrinkage, pinhole and fisheye.
2. It is recommended to add 0.1-2%, and stir evenly before use.
3. This series can replace imported acetylene glycol 420/440/465/485 series products.
[Packaging, storage and transportation]
Packed in 200kg, 50kg and 25kg plastic drums.
Storage and transportation of general chemicals. Store in a dry and ventilated place. The shelf life is two years.

In addition to their strong performance in reducing dynamic surface tension, this Gemini surfactant series—represented by Penetrant JFC—also enhances substrate wetting on difficult-to-coat surfaces such as plastics, metals, and low-energy materials. Their molecular structure enables rapid migration to the interface, ensuring uniform coverage during both spray and roll coating. This results in more stable application behavior, improved leveling, and significantly reduced film defects.

These surfactants maintain excellent compatibility with various resin systems, including acrylics, polyurethanes, epoxies, and waterborne formulations. Their high efficiency at low dosages makes them cost-effective for industrial applications. As non-ionic materials, Penetrant JFC and related products deliver strong chemical and thermal stability, ensuring reliable performance under different processing conditions.

Environmental considerations have been incorporated into the design. The series ensures low VOC contribution and reduced environmental impact, meeting modern regulatory and sustainability requirements.

When properly incorporated, the series significantly improves gloss uniformity, minimizes surface defects, and enhances the appearance and protective properties of final products. For manufacturers seeking high-quality, defect-free finishes, Penetrant JFC serves as an ideal and reliable surfactant choice.
