HYDROPALAT® WE 3221 is a silicone surfactant with the following characteristics and properties:

Function in Aqueous Systems: It is specifically designed to enhance substrate wetting in aqueous systems. It has a remarkable ability to significantly reduce the surface tension in water-based formulations. This property is crucial as it enables the liquid to spread more evenly and thoroughly on the substrate, ensuring better contact and adhesion.

Benefits in Coatings:

Defect Prevention: By improving wetting, it can effectively prevent surface defects such as craters and pinholes in coatings. This leads to a smoother and more flawless coating surface, enhancing the overall quality and appearance of the coated product.

Good Recoatability: It is highly recommended as an anti-crater additive with excellent recoatability. This means that when additional coats are applied, there are no issues related to poor adhesion or surface irregularities, allowing for a seamless coating process.

Flow and Leveling Improvement: In UV-curable formulations, it can improve the flow and leveling properties. This helps to create a more consistent and uniform coating film, reducing the occurrence of flow marks and improving the aesthetic appeal of the final product.

Applications: It is widely applicable in various coating systems, including architectural coatings and industrial coatings. Its performance characteristics make it an ideal additive for achieving high-quality coatings in different application scenarios.
