Many formulators of water-based coatings and printing inks struggle with a common problem: conventional wax emulsions contain external emulsifiers that may hurt water resistance, introduce unwanted foaming, or compromise long-term film performance. When your finished coating or printed film sticks together after stacking, gets scratched easily during handling, or fails to reach target matte appearance, it is time to consider emulsifier-free polyethylene wax dispersion.
BATON BD-6040B is an emulsifier-free aqueous polyethylene wax dispersion, designed to upgrade surface properties of waterborne formulations without extra surfactant additives. Unlike traditional wax emulsions stabilized by emulsifiers, this grade directly disperses PE wax particles into water, minimizing negative impacts on film water resistance and formulation compatibility.
Core Performance Benefits in Formulation
When incorporated into your water-based system, BD-6040B brings multiple surface improvements:
- Enhanced scratch resistance: Protect coated surfaces from marring and mechanical scratches during processing and end-use.
- Higher abrasion resistance: Reduce rub damage for printed ink layers and furniture coating films.
- Controlled matting effect: Achieve matte or semi-matte finish without heavy loading of matting powder.
- Excellent anti-blocking performance: Prevent stacked coated sheets or printed substrates from sticking together under pressure.
- Improved water resistance: The emulsifier-free design helps maintain better hydrophobicity of the dry film.
Typical Application Fields
BD-6040B fits a wide range of waterborne industrial formulations:
- Aqueous coatings and printing inks
- Wood and furniture water-based coatings
- Overprint varnishes for printed packaging
- Water-based adhesive systems
Key Technical Parameters
The values shown below are typical properties and do not represent binding specification limits for commercial batches.
- Appearance: White dispersion
- Active ingredient: Polyethylene wax
- Solid content: 40 %
- Ionic character: Nonionic
- Wax melting point: 130℃
- pH value: 10
- Particle size (D50): 2.5 µm
The 2.5 µm D50 particle size balances surface migration and uniform distribution in resin systems. Its nonionic nature enables good compatibility with most waterborne acrylic and PU dispersions commonly used in coating and ink factories.
Formulation Tips for R&D Engineers
Recommended addition dosage usually falls between 1–3 wt% based on total formulation weight. It can be added under low-to-medium stirring at the late mixing stage. High shear mixing is not required. Before mass production, always run lab trials to test compatibility, film gloss, anti-blocking and water resistance in your specific resin system.
Why Emulsifier-Free Wax Dispersion Matters
Standard wax emulsions use surfactants to keep wax particles suspended. Those emulsifiers stay inside the dry coating film, which can weaken water resistance and create foaming risks during production. Emulsifier-free PE wax dispersion removes that risk, making it ideal for high-performance wood coatings and packaging overprint varnishes where surface durability is critical.
Conclusion
For R&D and procurement teams looking for a reliable wax additive to improve slip, scratch resistance, anti-blocking and matte effect for waterborne coatings, printing inks and overprint varnishes, BATON BD-6040B emulsifier-free polyethylene wax dispersion offers a stable, high-performance solution.
