This wetting agent has been found to be an excellent alternative to problematic fluorosurfactants. Unlike fluorosurfactants, and most other surfactant chemistries, this acetylenic-based surfactant has the ability to dramatically reduce both equilibrium (static) and dynamic (high speed) surface tension properties, while providing low foam and low water-sensitivity properties. Dynol 604 surfactant promotes substrate wetting of waterborne systems such as coatings, inks and adhesives by effectively lowering both the equilibrium (static) and dynamic surface tension of aqueous systems. This is demonstrated by the very low surface tension values of a 0.1 wt % solution in water. These values represent greatly improved surface tension reducing capabilities compared to those available with traditional surfactants. In a formulated system, Dynol 604 surfactant will rapidly migrate to the interface, providing excellent coverage over low-energy or contaminated surfaces. In addition, since the Dynol 604 surfactant is based on acetylenic glycol chemistry, it will be low in foam, will have little or no impact on water sensitivity and is ideally suited for very low VOC applications. This combination of performance benefits makes Dynol 604 surfactant a suitable alternative where fluoro and silicone surfactants were previously required due to the limited equilibrium surface tension reduction capabilities of traditional organic surfactants. However, compared to fluoro or silicone surfactants, Dynol 604 surfactant will not impart excessive foaminess nor is it likely to interfere with recoatability/intercoat adhesion. It is used in metal coatings, wood coatings, printing inks, flexographic and gravure inks, other applications include floor polishes, leather coatings, metal/plastic primer and topcoats, architectural paints.
