Use of waxes
Today, there is a diverse range of waxes on the market. The most used waxes for
coatings and inks are based on Polyethylene, Polypropylene, Carnauba, Amid. Waxes
products based on Polytetrafluorethylene PTFE are also used as matting agents.
In contrast to silicas, waxes modify the surface properties of a paint film by floating
to the top of the surface. This phenomenon affects the following properties: the
degree of matt / gloss; slip and mar resistance; anti blocking and abrasion properties,
anti settling and surface tension.
Most of the products are delivered as micronized products, which are available in
a wide range of concentrates that are based on wax emulsions. Dispersions differ
according to particle size and particle size distribution.
