AERODISP®

Fumed Silica & Metal Oxide Dispersions

AERODISP® products incorporate a range of fumed silica and metal oxides into both aqueous and non-aqueous media. There are options available with regards to the solids content, pH and the surface charge of the dispersions. This allow for their use in a wide variety of coating systems.

Most grades have a low viscosity and don’t thicken systems like the powder AEROSIL® grades do. As a consequence, the formulator can achieve high solid levels whilst still maintaining a workable viscosity. This can give significant improvements in scratch resistance, anti-slip, anti-blocking and pigment/emulsion stability.

Cationic grades are very popular for high quality inkjet paper coatings as they are able to fix dyes and pigments, leading to improvements in colour gamut, print uniformity, print resolution and smudge/rub/water resistance.

There are also some speciality grades such as the AERODISP® G 1220 which is used as an anti-blocking agent in PET films. AERODISP® W 1244 is used in the intumescent, silicate-based, layer incorporated into fire-resistant glass.

Features

Fumed silica, aluminium oxide or titanium dioxide dispersions. Various solid loadings available.
Mostly based on aqueous media but there is also a product carried in glycol and one in MPA.
Different pH grades available for use in cationic or anionic systems.
A range of stabilisation salts available for improving compatibilty with your systems.
Most grades are low viscosity dispersions and don't lead to viscosity build (unlike AEROSIL® grades).

Benefits

Liquid nature of AERODISP® makes it easy to handle and work with i.e. no dust as is typical with fumed silica powder.
High ink absorptivity when formulated into photo inkjet paper sizing.
Can be used as a polishing agent. Increased hardness and scratch resistance.
Improves the mechanical properties of latex rubber and provides anti-blocking in PET film (AERODISP® G 1220).
Used as an anti-slip additive in some systems e.g. paper bags.
Enhances the colloidal stability of various different systems through a Pickering stabilisation effect.

Typical Applications

Used in the paper and textile industry to enhance anti-slip properties and create non-slip finishes.
Photo inkjet papers and coatings for pigment absorption/fixing; reducing water sensitivity and improving colour gamut.
Increases hardness and scratch resistance in paints.
Solid particle stabilisation e.g. pigments in aqueous inks.
Anti-blocking agent in PET films.
Polishing metal and metal oxide layers.
