Foam formation is one of the most common challenges encountered during the manufacture of paints and coatings. However, visible foam is rarely the real problem.
What truly affects product quality and process efficiency are the consequences it causes:
- Entrapped air in the formulation.
- Surface defects such as craters or microbubbles.
- Application difficulties.
- Poor leveling.
- Reduced product stability during storage.
- Loss of productivity and rejection of finished batches.
For this reason, selecting a defoamer should not be based solely on its ability to eliminate foam. Every formulation has different characteristics and requires specific technologies depending on the system, the raw materials used, and the expected performance.
There is no single defoamer that is the best solution for every paint formulation.
Different Technologies for Different Needs
Some formulations require silicone-free technologies to avoid potential incompatibilities, while others prioritize maximum efficiency at low dosage levels, ease of incorporation into the system, or long-term stability of the finished product.
Understanding the technical characteristics of each raw material makes it possible to compare their benefits and evaluate which one may be best suited to the requirements of each application.
At Corquimia, we distribute a wide range of ESQUIM defoamers for paints and coatings. We provide our customers with the technical documentation for each product, including Technical Data Sheets, Safety Data Sheets and, where applicable, manufacturer certificates, to facilitate the evaluation of each raw material.
We highlight the following products for the paints and coatings industry:
ESQUIM DP-058A: Next-Generation Silicone-Free Technology
When a formulation requires avoiding the use of silicones, ESQUIM DP-058A offers a concentrated silicone-free technology developed for applications where traditional defoamers may cause compatibility issues.
It is particularly suitable for emulsion paints, latex systems, paper manufacturing, wastewater treatment, and textile processes.
Its main characteristics include:
- Concentrated silicone-free technology.
- High efficiency at low dosage levels.
- Excellent storage stability.
- Stable performance over a wide pH and temperature range.
- Water-dispersible for easy incorporation into the system.
Its key strength is delivering outstanding defoaming performance in applications where the presence of silicones is not desirable.
ESQUIM A-1250: Designed for Water-Based Paints and Systems
ESQUIM A-1250 has been specifically developed to prevent entrapped air formation for the formulation of water-based paints, adhesives, and synthetic latex systems. Its silicone-free formulation provides high performance while avoiding the drawbacks associated with silicone-based technologies.
Its main characteristics include:
- Specially designed for water-based systems.
- High efficiency at low dosage levels.
- Maintains its defoaming properties during long-term storage.
- Compatible with both water-based and solvent-based systems.
- Low viscosity, allowing easy incorporation even under low shear conditions.
- Non-ionic, self-emulsifying character.
Its main advantage is the combination of ease of incorporation, stability, and high performance in water-based formulations.
ESQUIM A-8189: A Versatile Solution for Multiple Applications
For manufacturers looking for a general-purpose silicone-free solution, ESQUIM A-8189 offers a versatile technology suitable for a wide range of industrial applications, including paints, latex systems, paper manufacturing, water treatment, and textile processes.

- Non-ionic self-emulsifying system.
- Compatible with both water-based and solvent-based formulations.
- High stability across a wide range of pH and temperature conditions.
- Maintains high efficiency at low dosage levels throughout storage.
Its main strength is its versatility, making it suitable for a broad range of industrial processes requiring a silicone-free defoaming solution.
ESQUIM DP-030A: Maximum Efficiency at Very Low Dosage Levels
ESQUIM DP-030A combines active polymers with and without silicone to create a synergistic effect, providing outstanding defoaming performance in both water-based and solvent-based coatings.
Its main characteristics include:
- Blend of silicone and non-silicone polymers.
- High efficiency at very low dosage levels.
- Water-dispersible.
- Suitable for both water-based and solvent-based formulations.
- Recommended for addition during the highest shear stage to promote homogeneous distribution and reduce the occurrence of surface defects.
Its main advantage is delivering high defoaming performance while optimizing dosage levels.
Technical Information to Support Raw Material Selection
Every formulation has its own specific requirements. For this reason, it is important to understand the technical characteristics of the different technologies available before selecting a raw material.
While some formulations require silicone-free technologies, others prioritize storage stability, ease of incorporation, or maximum efficiency at low dosage levels. Understanding these characteristics helps facilitate the evaluation of the available raw materials.
At Corquimia, you will find a comprehensive range of ESQUIM defoamers for paints and coatings, together with the technical documentation required to understand the performance of each product and select the raw material that best meets the requirements of your application.
