Water-Based Coatings

 

 

Powder Coatings Table and ChairsCray Valley has a small, yet versatile, selection of CRAYVALLAC® surface modifiers specifically developed to enhance the surface lubricity of water-based coatings. These surface modifiers are available as both micronised powders and easy to handle aqueous dispersions. CRAYVALLAC® surface modifiers are suitable for use in a wide range of water-based coating systems, where they provide the formulator with the following surface enhancements:

  • Control of matting and silk effect.
  • Improved scratch, slip, rub and abrasion resistance.
  • Enhanced blocking and water repellency.
  • Greater solvent and heat resistance.
  • A smooth, silky-feel and appearance.

Due to their pre-wetted and pre-dispersed nature, CRAYVALLAC® aqueous dispersions are easier to incorporate into water-based coating systems. Compared to these, the CRAYVALLAC® micronised powders generally require the addition of a surfactant to facilitate the dispersion process.

CRAYVALLAC WN-1135: Extremely tough micronised polypropylene wax for soft-touch, lubricity and matting.
CRAYVALLAC WN-1495: Micronised polyethylene wax for enhanced scratch and slip.
CRAYVALLAC WN-2000: Micronised polyethylene wax for enhanced lubricity and heat resistance.
CRAYVALLAC WF-3200: Micronised polyethylene with PTFE for enhanced lubricity control.
CRAYVALLAC WW-1001: Polyethylene wax dispersion for enhanced scratch and slip.
CRAYVALLAC WW-1074: Oxidised polyethylene dispersion for control of lubricity.
CRAYVALLAC WW-1077: PTFE modified polyethylene dispersion for enhanced surface protection.
CRAYVALLAC WW-9500: Modified polypropylene dispersion for matting and to improve mar and rub resistance.
