[nanoPost] Anti-aging for facades with a silica / acrylate nanocomposite binder

Company Germany

Silica/acrylate nanocomposite dispersions are a new class of binders for waterbased coatings. Film formation of these nanocomposite dispersions takes place at the same temperatures as for acrylate dispersions having the same polymer composition, whereas film hardness and strength are strongly improved. The films are highly transparent, provide an excellent hardness/elasticity compromise, do not swell in water and show very low water whitening.
Further film properties are high heat resistance, water vapour permeability, solvent resistance, adhesion to mineral substrates and a favourable burning behaviour.

Silica/acrylate nanocomposite dispersions therefore are a highly promising approach for solvent-free coatings. Special application features for paints are low dirt pick-up and high blocking resistance.
