Typical Properties:

Product Description：

NV-AD604 and NV-AD607 are 100% active, low-VOC, nonionic wetting agents based on ethoxylated acetylenic glycol chemistry. By controlling the degree of ethoxylation, the two grades provide different balances of dynamic wetting, surface tension reduction, water compatibility and formulation compatibility.
NV-AD604 is optimized for strong dynamic wetting and low-foaming performance, making it particularly suitable for difficult-to-wet and low-energy substrates. NV-AD607 has a higher degree of ethoxylation, providing enhanced hydrophilicity, water dispersibility and formulation compatibility while maintaining effective substrate wetting.
Both products provide efficient reduction of equilibrium and dynamic surface tension and can help improve substrate wetting, flow and leveling while reducing wetting-related surface defects.

Key Benefits & Features：

Superlative Interfacial Activity: Both grades dramatically reduce equilibrium and dynamic surface tension at low addition levels (0.1 wt%), helping reduce common wetting-related defects,like crawling, pinholes, retraction, and fisheyes.
Low Foaming Character: Provides rapid wet-out under high-speed mechanical application (spraying, roller, or printing) with a low tendency to stabilize foam.
Good Recoatability and Intercoat Compatibility:The product is designed to provide effective wetting while maintaining good recoatability and intercoat compatibility in properly formulated systems.
Broad Formulation Compatibility:NV-AD604 and NV-AD607 can be formulated over a broad pH range. Based on our technical evaluation, they are suitable for systems covering approximately pH 3–12. Actual long-term stability and performance should be evaluated in the specific formulation, particularly under extreme pH, high electrolyte concentration, or elevated temperature conditions.
Environmental Profile: Low VOC and APEO-free. 

Recommended Applications：

Water-based Printing Inks & OPVs: High-speed inkjet, flexographic, and gravure inks over packaging stocks. (NV-AD604 is highly recommended for ultra-high speed; NV-AD607 is ideal where ultimate solution clarity is vital).

Water-based Industrial Coatings: Automotive OEM, architectural trim paints, industrial wood coatings, and primers for plastics/metals.

Water-based Adhesives: Wetting and coverage over low-energy plastic lines or silicone release liners.

Specialty Systems: Waterborne Polyurethane (PU) systems, luxury leather coatings, and high-performance fountain solutions.

Product Selection Guide

NV-AD604 : Optimized for applications requiring maximum dynamic surface tension reduction and optimized for very low foaming. It excels in high-speed coating/printing on highly low-energy or difficult-to-wet plastic films.

NV-AD607: Formulated with an increased degree of ethoxylation to provide enhanced water solubility, exceptional formulation clarity, and broader resin compatibility, while maintaining highly robust substrate wetting performance.

Formulation Guide & Usage Level:

Recommended Dosage: Typically added between 0.1% and 2.0% based on the total formulation weight.

In clear formulations, it can be highly effective at 0.1 wt%. For highly resinated or pigmented systems, loading may be increased up to 1.0 wt%.

Addition Order:: Products should be added directly into the formulation stage after the polymer emulsion (binder) and pigment introduction.

Incorporation:  Standard mechanical agitation for 15 to 30 minutes is fully sufficient to ensure complete, homogenous dispersion. High-shear equipment is not required.

Handling & Precautions

Store tightly sealed in a cool, dry, and well-ventilated storage space away from direct heat sources.
