Arichemie at the European Coatings Show 2013

28.01.2013 | The specialist for pigment preparations will be presenting a multitude of aqueous, VOC-free or BIT-free pigment preparations. With the use of renewable raw materials, Arichemie is counting on improved environmental tolerability and individuality for the user – customer-specific for UV-applications.

EPPSTEIN. The demands on pigment preparations are increasing. A greater variety of different applications and the specialisation of users also demand a multitude of colouristic and applied technological specialty grades, in addition to assured reproducibility and availability. In the meantime greater importance has also been placed on the environmental compatibility of coatings and thus their constituents. Arichemie, with its multitude of different pigment preparations and solution-oriented advisory services and well-founded know-how, is optimally positioned to address these needs.

The aqueous pigment preparations of the Vocaflex series provide strong and brilliant colour accents with high quality organic and inorganic pigments. The very light-fast and good weathering stability of the pigments used is seen in the level of their stability, especially in the critical area of yellow, red and orange tones. The Vocaflex “classic” series has been in use for decades as an aqueous VOC-containing pigment preparation with adjusted colour intensity. Today, it is used preferably for printing inks.

Vocaflex has been increasingly adapted to meet the requirements of colouring pastes used in the building paints industry. This requires a new choice of raw materials which differ from the Vocaflex “classic” series by their adjusted colour strength and density.

Vocaflex-LF includes VOC-free and VOC-low aqueous pigment preparations with adjusted density, which are suitable for dosing and mixing systems. The main areas of application are dispersion paints for facades, interior rooms and plasters. In addition, they are also compatible with many different aqueous paint and lacquer systems. The pastes satisfy the requirements for paints complying with the requirements of RAL UZ 102 and the 2nd level of the EU-Decopaint Directive 2010.

The Vocaflex-EN series has been further extended to meet the technical requirements of the toy norm EN 71. This aqueous pigment paste without benzisothiazolone (BIT) is available in 20 colour indices and very well suited for uses such as children’s paints, window colours or silk paints.

Pigment preparations based on renewable raw materials
Arichemie is focusing on renewable raw materials in many resin-based pigment preparations. For example, in the case of Vocaplast-P, which contains the “green polyol” Sovermol - the pigment preparation was developed in collaboration with Cognis.
Vocaplast-L is a linseed oil-based paste which not only achieves excellent transparency in wood varnishes with various colour tones, but is also used in bio-plastics based on maize or potato starch.
Aricolor-N is the latest development from Arichemie, which is based on castor oil or rapeseed oil, or with a carrier specified by the customer for a particular application. It produces excellent processing results for solvent-containing lacquers, sports floors as well as thermoplastics.

The UV-curing pigment preparations of the Vocaplast-UV series are based on customer-specific resins. They are preferentially used in printing inks and surface coatings, and are based on free-radical or cationic-curing systems.

Optimally suited for each application
The most suitable pigment is selected according to the area of application. This is where the many years of experience and the extensive know-how of Arichemie GmbH, which is situated in the Hessian town of Eppstein, comes into play – the company has been specialising in the development of pigment preparations in the B2B area since 1956. For Arichemie GmbH, solution-oriented collaboration with the customer takes first priority. As a mid-sized company, it is able to react flexibly, specifically and individually to customer needs and find the optimum product for the respective application, together with the customer.
