Main features

l Increasing the hydrophilicity of the product, increasing the solubility in water, and improve wetting and defoaming properties.

l Due to the different solubility in water and ethylene oxide level, it can be used as low-foaming, no-foaming or defoaming wetting agent for water/alcohol-based adhesives, coatings and inks. Also can be used for some solvent-based systems.

l No APEO, non-toxic.

Usage

Ensure sufficient mix when in use.Surfadol400 should be added and mixed after other surface-active agents in system.Pigments, fillers or other solid should be added after Surfadol 400 has been evenly mixed. It will ensure effective wetting and foam suppression.

Suggested Addition

0.2% - 2.0% wt. on total formula. Ultimate assessment and confirmation depend on experiments.
