What is a Silicone Leveling Agent？
A silicone leveling agent is a leveling additive based on modified polysiloxane to improve the flow and leveling of the liquid films. This silicone additive has improved surface tension reduction with the following high-quality performances when used in coatings and inks.Â
- Lower surface tension than the common levelling agent.
- Polysiloxane structure to reduce surface defects.
- Compatibility with waterborne, solvent-based, UV coatings and inks.
- Reduced dosage starts from 0.03%, depending on the formulation.
- Enhanced slip and surface smoothness with better wetting.

Celotech Ruico Silicone Leveling Agent Models
We have designed four models of excellent silicone leveling agents for water-based, radiation-cured, solvent-based, and solvent-free coatings and inks.
Provides smooth hand feel, anti-shrinkage, and scratch resistance. Its strong surface tension reduction ensures matte powder distribution, anti-adhesion, and good compatibility with minimal fogging.
A silicone surfactant with an outstanding effect of surface tension reduction, it delivers a smooth and glossy surface, and improves anti-adhesion. It provides a smoothness and leveling performance between RT-141 and RT-145.
Smooth and level the coatings, destabilize foam with balanced surface tension performance. This model helps the coating with good transparency and extremely low risks of fogging, and does not affect recoating.
This model contains a pure long-chain silicone structure for enhanced leveling, smoothness and fullness. It has balanced surface tension, which can ensure the coating has good transparency.

Reduce common coating surface defects such as craters, pinholes, and orange peel.
Enhance surface smoothness, ensure the coating gloss, and visual appearance.
Compatible with acrylic, polyurethane, epoxy, and polyester resin formulations without affecting coating stability.
Cost-effective solution with low addition rates and no compromise on performance.
Applicable in water-based, solvent-based, and UV-curable coatings, as well as printing inks.
Silicone Leveling Agent Applications
Due to our superior leveling performance and leading technology, our silicone leveling agents can be widely applied in many kinds of coatings and inks.
Silicone leveling agents are ideal for wood coatings that need matte uniformity, smooth hand feel, and better scratch resistance. They help the film wet wood surfaces evenly, reduce shrinkage cavities and gloss variation, and deliver a smoother, more consistent finish on furniture and wood panels.
Silicone leveling agents suit industrial coatings that need fast wetting and strong surface tension reduction. They improve flow on difficult substrates, help reduce craters, fish-eyes, pinholes, and orange peel, and give water-based or solvent-based systems a cleaner, more uniform finish.
Silicone leveling agents are a balanced choice for automotive coatings that demand smooth flow and stable leveling. They help form a uniform film during spray application, reduce pinholes and orange peel, and maintain gloss, smoothness, and recoatability in OEM and refinish systems.
Silicone leveling agents perform well in printing inks by promoting even wetting, smoother transfer, and clearer surface definition on paper or film. Their controlled leveling helps reduce shrinkage defects and uneven laydown, while supporting print gloss and a cleaner, more stable printed appearance.
Silicone leveling agents are a strong option for overprint varnishes that need high slip, smooth leveling, and reliable recoating. In protective varnish systems, they help the coating spread uniformly, improve fullness and clarity, and reduce pinholes or texture defects without sacrificing intercoat adhesion.
Silicone leveling agents are suitable for leather finishing systems that require a soft hand feel, smooth slip, and an even topcoat. They improve coating flow across flexible leather surfaces, help minimize texture irregularities and pinholes, and deliver a refined finish with stable gloss and pleasant touch.
Packaging and Storage
We packed the silicone leveling agent with drums in 25 kg and 200 kg, as well as customized packaging options.Â
Keep the packaging sealed and store in dry and cool areas at 5°C to 35°C. The shelf life of our silicone leveling agent is 12 months from the date of production.

Customer Testimonials
We used RT145 silicone leveling agent in our wood coating system. The gloss improved and the orange peel we used to see after spraying is basically gone. The finish looks much smoother now.
MaryTechnical ExecutiveCelotech Ruico leveling agent is good. The dosage is small, and the price is reasonable. The sales is active, quick to respond, and has come to meet us many times. We appreciate their technical support, which is better than that of others. We have made a new order, and we wish their support for further development.
JasonProcurement ManagerThis leveling agent quickly integrates into our formulation without causing haze. The coating finish and the production efficiency are improved. We are thinking of trying other additives.

FAQ About Silicone Leveling Agent
The most matched leveling agent with your system and requirements is the best. Silicone leveling agent provides stronger leveling and surface effects, while acrylic leveling agents offer better compatibility and stability in some systems.
It mainly depends on your coating system and your performance requirements. RT149 is mainly for the solvent system, RT141 causes minimal fogging with excellent compatibility, RT143 provides moderate performance, and RT145 is suitable for recoat. You can email us with your system and requirements to get more technical guidance.
Compared to common leveling agents, Celotech Ruico silicone leveling agent will not cause severe foam issues. RT145 is good for stabilizing foam and has extremely low fogging risks.Â
Yes. Our silicone leveling agent can improve flow and surface leveling. They can help reduce micro-defects and enhance DOI in high-gloss coatings.
Normally, our silicone leveling agent has minimal impact on open time and drying speed when the dosage is suitable.
