Kynar® ADX 111: new adhesive PVDF grade for powder coatings

Published on 2006-05-17. Author : SpecialChem

Arkema has enhanced its Kynar® ADX range with Kynar® ADX 111, a new grade capable of adhering to metals without the need for an adhesion primer.

Kynar® ADX 111 offers a cost-effective solution which also makes life easier for processors.

Kynar® ADX 111 is the only coating entirely formulated from a fluorinated polymer requiring no adhesion primer. This coating process using Kynar® ADX 111 stands out by its straightforward application and its effectiveness: Kynar® ADX 111 may be applied by electrostatic dusting or by fluidised bed coating to produce highly adhesive coatings with a small thickness (under 200 microns) on substrates such as steel and aluminum.

In addition to its remarkable adhesive performance, the chemical nature of Kynar® ADX 111 also ensures outstanding chemical stability, therefore making it insensitive to corrosion, solvents and the decay caused by most chemicals.

Kynar® ADX 111 furthermore exhibits excellent mechanical properties as well as good thermal stability (up to 130°C).
Thanks to its specific characteristics and outstanding properties, the new Kynar® ADX 111 is therefore highly suitable both for the external anticorrosion coating of various parts and for the lining of hollow vessels designed to contain chemical agents.

Other technical solutions can also be used:

  • In the coextrusion process, the Kynar® ADX resin can be combined with most polymers (polyethylene, polyamide, polyester, etc.) to ensure optimum performance synergy, in particular in terms of mechanical, chemical and barrier properties.
  • In processes requiring solvents, the Kynar® ADX resin dissolves to be used on metals with or without additives, for example as an excellent adhesion primer or as a binder.

The Kynar® trademark belongs to Arkema Group companies.

A global chemical player, Arkema combines 3 related and integrated business segments: Vinyl Products, Industrial Chemicals, and Performance Products. Present in over 40 countries with 18400 employees, Arkema achieves sales of 5.7 billion euros (2005). It has research centers in France, the United States and Japan.
