Solving Interfacial Conflicts for Surface Perfection
In high-performance systems, a standard paint leveling agent often solves one problem but creates another, such as micro-foaming or adhesion loss. Our leveling agents for paint focus on “Balance Engineering,” which can help you achieve a flawless surface without sacrificing your coating’s structural integrity.
| Critical Challenges | Standard Additives (The Risks) | Our Solution | The Technical Impact |
| Substrate Wetting | Poor coverage on oily or low-energy surfaces. | Dynamic tension reduction for ultra-wetting. | Eliminates Fish-eyes and surface voids. |
| Film Durability | High surface friction leads to easy scratching. | Controlled slip with high-density siloxane. | Superior Mar & Scratch Resistance. |
| Intercoat Integrity | Surface migration causing recoat failure. | Zero-migration modified polymer structures. | Guaranteed Adhesion for multi-layer lines. |
| Matte Consistency | Uneven matting agent distribution (clouding). | Controlled orientation of inorganic fillers. | Perfect Gloss Uniformity across large areas. |
Paint Leveling Agent Grades
Our teams have developed a range of leveling agents for paint, and we would assist you in choosing the most suitable paint leveling additive.
High-performance surface control additive designed for matte systems, improving uniformity, scratch resistance, and defect control in demanding coatings.
Fast wetting silicone additive for low-energy or contaminated substrates, effectively eliminating craters, fish-eyes, and surface voids.
Universal leveling agent balancing flow, compatibility, and surface smoothness across waterborne, solvent-based, and UV systems.
High-slip solvent-based leveling additive ensuring excellent flow, smooth surface finish, and reliable recoating performance without adhesion loss.
Leveling Solution Cases
You can refer to the following cases to evaluate whether our leveling agents for paint can resolve your issues, and we also offer customized paint leveling solutions.
A waterborne metal coatings manufacturer experienced recurring craters and fish-eyes during spray application, especially on substrates with residual oil contamination. The defects became more severe under high-speed production conditions, resulting in unstable appearance quality and increased rework rates.
After using Celotech Ruico RT143 leveling agent for paint in the formulation:
- Substrate wetting on difficult metal surfaces was significantly improved
- Fish-eyes and crater defects were reduced by approximately 80%
- Coating flow and film uniformity became more stable under continuous spraying conditions
- Rework was decreased and efficiency was increased during large-batch production
A furniture coating company faced inconsistent matte appearance and visible gloss variation on large wooden panels. The matte coating surface also showed poor scratch resistance during packaging and transportation.
Our paint leveling agent RT141 helped them:
- Improved matte powder uniformity, reduced visible gloss banding on the final film
- Enhanced smoothness and hand feel without affecting recoating performance
- Achieved scratch resistance during internal abrasion testing significantly reduced
- Process stability under different shear conditions was improved, supporting consistent production quality
Our Paint Leveling Agent Advantages
Optimized for water-based acrylic, solvent-based PU, and high-solid UV systems， our paint leveling agents can work smoothly in complex formulations without oil spots or flocculation.
Designed for matte coatings, Celotech Ruico paint leveling additives can help matte powder distribute evenly, reducing whitening, patchiness, and gloss variation on large surfaces.
Our leveling agents for paint can form a molecular-level slip layer on the coating surface, reducing the friction and improving scratch resistance during transport and handling.
With up to 100% active content, our paint leveling agents deliver full performance at very low dosage levels (0.03%–0.5%) and can reduce the overall formulation cost.
Dynamic Surface Tension Control for Wetting and Foam Balance
In coating formulation, wetting and defoaming are often hard to balance. Powerful paint leveling agents can wet the substrate rapidly, eliminating surface defects. However, when surface tension is reduced too aggressively and molecular weight distribution is poorly controlled, micro-foam can easily become trapped inside the paint film.
Celotech Ruico paint leveling additives are engineered with narrow molecular weight distribution technology in the polyether segments. This design helps optimize dynamic surface tension, rapidly wetting the substrate during spraying or brushing with low foam stabilization.
With our paint leveling paints, you do not have to add excessive defoamers to resolve surface defects, avoid issues like coating turbidity or gloss reduction caused by additive overloading.
Migration-Controlled Silicone for Balanced Slip and Adhesion
Long-chain siloxanes deliver excellent slip, but conventional types tend to migrate to the coating surface and form a non-bonding layer. This phenomenon can lead to serious intercoat adhesion failure and delamination risks in wood coating, automotive finishes, and other coating systems.
Our premium paint leveling agents, including RT149 and RT141, use specially modified functional silicone technology. During film formation, the molecules are designed to arrange in a controlled way rather than simply floating to the surface. They can interact with the resin matrix through physical entanglement and hydrogen bonding.
This structure provides smooth slip, scratch resistance, and mirror-like leveling while maintaining strong intercoat adhesion. Our paint leveling agents can help you achieve both surface aesthetics and coating durability in one system.
Reliable Supplier for Full Formulation Balance
Established over a decade ago, Celotech Ruico is a nationally recognized “Little Giant” enterprise with strong R&D capability and globally certified quality systems. We deliver high-performance paint leveling agents, acrylic emulsions, defoaming agents, PU thickeners, and other specialty chemicals in paint and coating applications.
More importantly, we do not only focus on individual chemical additives. In many cases, formulators face performance issues at the system level even with high-quality raw materials such as paint leveling additives. Our expertise lies in helping you balance and optimize additive interactions within the full formulation, enabling each component to deliver its best performance in real coating systems.
