VINNAPAS ® dispersions provide primers<br />
with the necessary properties for the<br />
next layer to function properly.<br />
General Benefits<br />
• Good impregnation due to high penetration<br />
into pores<br />
• Excellent barrier properties<br />
• Low and uniform absorbency<br />
• Good adhesion of emulsion paints and coatings<br />
even on critical substrates<br />
• High compatibility with different substrates<br />
• Good consolidation of construction surfaces<br />
• Bridging of small cracks<br />
Application Spectrum<br />
• Adhesion-promoting layer<br />
• Equalization of low absorption properties<br />
• Barrier layer for migration protection<br />
• Construction surface consolidation<br />
• Stain blocking/resistance<br />
Ideal for Many Applications<br />
Most buildings are built one layer upon the next.<br />
Primers are essential to ensure the long-term<br />
durability of each subsequent layer, either for<br />
interior or exterior applications. Under outdoor<br />
conditions, primers require high water repellency<br />
and good barrier properties, which is where<br />
hydrophobic dispersions such as VINNAPAS ® are<br />
24<br />
needed. Dispersions with small particles penetrate<br />
well into the surface and consolidate open-pore<br />
substrates such as concrete, cement and gypsum<br />
plasterboards and control the absorbency of the<br />
substrate.<br />
