Wetting penetrant WE 3320 is a remarkable product with several distinct features and benefits:

Chemical Composition and Physical Properties:

It is a non-ionic surfactant with 100% active ingredients. This chemical composition gives it excellent surface-active properties, allowing it to interact effectively with various substances.

In terms of its physical form, it is a clear to hazy liquid. It has a viscosity of approximately 200 mPa·s, a water content of around 10%, a cloud point of about 90 °C, a pH of approximately 6.5, and an HLB value of around 14.

Wetting and Dispersing Abilities:

WE 3320 has outstanding wetting capabilities. It can rapidly spread over the surface of a substrate, significantly reducing the surface tension between the liquid and the solid. This enables the liquid to wet the substrate thoroughly and uniformly, which is crucial for achieving good adhesion and bonding in various applications.

It also exhibits excellent pigment dispersing and stabilizing properties. This is beneficial in applications where pigments need to be evenly distributed and stabilized, such as in the coatings and paints industry. It helps to prevent pigment settling and agglomeration, resulting in a more consistent and high-quality product.

Environmental and Performance Advantages:

It is a PEO (polyethylene oxide)/HAPS (Alkylphenol Ethoxylates) free product with zero VOC (Volatile Organic Compounds). This makes it an environmentally friendly alternative, meeting the increasing demand for sustainable and low-emission chemical products.

The use of WE 3320 can lead to an improvement in gloss. It helps to create a smoother and more lustrous surface, enhancing the aesthetic appeal of the final product.

Additionally, it offers reduced water sensitivity, which means that the treated materials are less likely to be affected by water, improving the durability and performance of the product in wet or humid environments.

Applications:

It is widely used in waterborne coatings as a wetting and dispersing agent. It enhances the color development and acceptance of coatings, as well as improving the wetting of the substrate, resulting in better coating performance.

Due to its excellent properties, it can also be applied in other industries such as inks, adhesives, and sealants, where wetting, dispersing, and stabilizing properties are required.
