Non-Ionic Wetting Agent Overview
A non-ionic wetting agent is a kind of special non-ionic surfactant, usually based on polyether or siloxane structures. It is used to improve the wetting and spreading of liquids on solid surfaces. As a leading wetting agent manufacturer in China, Celotech Ruico provides superior non-ionic wetting agents with easy-to-apply formulations.
- Rapid substrate wetting property
- Even dispersion for pigment and filler, not limited to coatings
- Improved flow & leveling
- Lower foaming property than similar products
- Broad compatibility with water-based systems

Celotech Ruico Non-Ionic Wetting Agent Superiorities
We focus on delivering reliable non-ionic wetting agent solutions to help you achieve optimal coating performance with the following product advantages.

Our nonionic wetting agents can reduce surface tension rapidly, allowing liquids to fully wet substrates and pigments. They can help ensure uniform coverage and prevent defects such as fish eyes or floating color.

With excellent compatibility, our wetting agents can work effectively across a wide range of water-based coatings, resins, and additives. They’re suitable for wood coatings, industrial paints, printing inks and various other applications.

Celotech Ruico nonionic wetting agents were formulated with low foam during mixing and application. By reducing foam, the surfaces can be smoother with fewer defects, helping you decrease the amount of defoamers.

Our wetting agents are produced without APEO or harmful emulsifiers, which can meet global environmental standards. With low content and eco-friendly formulation, our wetting agents contribute to sustainable development.
Non-Ionic Wetting Agent Uses
Celotech Ruico Non-Ionic Wetting Agents have a wide range of applications in paints, coatings, and inks.

We have developed models of non-ionic wetting agents for demanding latex paint and universal construction paint. They can enhance the fillers and pigment dispersion in latex paint, ensuring a smooth and uniform finish. Improving the workability and leveling, they will help you get easier applications for both interior and exterior environmentally friendly coatings. With low foam properties, they reduce defects such as pinholes or surface bubbles. Compatible with various eco-friendly paints, they support sustainable and high-performance building coatings.

Our non-ionic wetting agents are also suitable for wood coating to make the coating surface smoother and more even. They enhance substrate wetting, allowing better penetration and adhesion to primers and topcoats. By reducing foam during application, they help achieve defect-free finishes with high gloss and clarity in varnishes. Additionally, their broad compatibility enables leveling and consistent performance across clearcoats and protective wood coatings.

Celotech Ruico has a nonionic wetting agent designed for printing inks. With good dispersibility and stability for both inorganic and organic pigments, it ensures smooth and consistent ink formulations. By improving the substrates’ wetting, the wetting agent ensures uniform coverage and consistent color density. Our wetting agents focus on low-foam properties, helping you prevent air entrapment during printing for free defects such as pinholes and streaks.

Our nonionic wetting agents are also applied in automotive coatings. They can enhance the wetting of pigments and fillers to get smooth and uniform finishes. The advantages of reducing foam, they are ideal for you to achieve defect-free surfaces. By improving dispersion stability, the agents support consistent color and gloss across large production batches. Compatible with various resins and solvents, you can use them for primers, basecoats, and clearcoats in automotive manufacturing.

In traffic coatings, our non-ionic wetting agents are good to improve the wetting and dispersion of pigments in high-solids, fast-curing formulations. They can reduce surface defects, such as pinholes and streaks with better surface leveling. With minimal foaming, you can get a more uniform coating thickness on large pavements, parking lots, and industrial floors. They are compatible with different resin systems, helping you achieve smooth and long-lasting finishes under heavy traffic conditions.
