HYDROPALAT® WE 3220 is a silicone surfactant that offers several notable features and benefits for various applications, especially in the coatings industry. Here is an introduction to it:

Function in Aqueous Systems: It is specifically designed to improve substrate wetting in aqueous systems. It shows a strong ability to reduce the surface tension in water-based systems, which is crucial for ensuring that the coating or other formulations can spread evenly and thoroughly on the substrate.

Performance Benefits:

Excellent Substrate Wetting: It provides excellent wetting properties in a wide range of applications such as aqueous industrial coatings, wood coatings, automotive coatings, and exterior paints. This helps to achieve better adhesion of the coating to the substrate and a more uniform coating film.

Surface Defect Prevention: By enhancing the wetting ability, it can effectively prevent surface defects such as craters and pinholes, resulting in a smoother and more flawless surface finish.

Good Recoatability: It is recommended as an anti-crater additive with good recoatability, which means that subsequent coats of the coating can be applied smoothly without issues related to poor adhesion or surface irregularities.

Flow and Leveling Improvement in UV-curable Formulations: It can also be used in UV-curable formulations to improve the flow and leveling properties, ensuring a more consistent and high-quality coating result.

Physical Properties: It has a solid content of approximately 87.5% and a density of around 1.04 g/cm³. The color is relatively light, with a maximum color value of 2.

Solvent-free Version: The solvent-free version of HYDROPALAT® WE 3220 is HYDROPALAT® WE 3221, which provides an alternative for applications where solvent-free formulations are required.
