COVENTYA SAS joins ADAL (Association for the Development of Anodized or Lacquered Aluminium)

aluminum wire2

After the acquisition of Politeknik Metal and the launch of the new ALUMAL range, COVENTYA SAS is strengthening its position in the aluminium building market and will join the ADAL on 1 January 2018.


ADAL brings together manufacturers of the surface treatment industry for aluminium: anodising lines, lacquerers, suppliers of chemical treatments and paints. The association aims to promote the use of anodized and lacquered aluminium, in particular through its Quality policy. In France and North Africa, for example, it awards QUALANOD labels for anodizing, as well as QUALICOAT and QUALIMARINE for lacquering. ADAL also manages the QUALIDECO label for decorative aspects (faux-wood type etc.).

COVENTYA announces the release of TRISTAR HP, an innovative decorative chrome process

Car Decorative reduced3

TRISTAR HP SYSTEM is COVENTYA’s latest technology for providing a High Performance Trivalent based Decorative Chrome deposit with Russian Mud corrosion and up to 60 hours CASS resistance on metal and plastic substrates.  The System is specifically designed to meet today’s requirements of automotive standards for interior and exterior Trichrome applications.

TRISTAR HP SYSTEM consists of several interacting layers (CUBRAC Acid Copper, CRITERION Sulfur-Free Nickel, CRYSTAL Bright Nickel, CRITERION Micro-Porous Nickel and TRISTAR 300/700 Series Trichrome) based upon electromotive potential that provide a barrier to corrosion.

No additional process steps are required, present process sequence for Hexavalent Chrome is utilized, providing low conversion and replenishment cost.

For applications that also require Neutral Salt Spray or Humidity protection, a complete line of Post Treatments are available to enhance the performance of the TRISTAR HP SYSTEM.

Tomorrow is Today, the TRISTAR HP SYSTEM does not depend upon Reach initiatives; it is ready for Market now!

COVENTYA helps to make fascinating fasteners

Fasteners C. Kaiser version WEB 4

There are many challenges in the life of a fastener.Enduring multi-functionality is a must.

Corrosion-induced malfunctions such as setting and wear as well as the unintentional loosening of a connection can be prevented by a multi-layer corrosion protection system. A first layer of zinc or zinc alloy provides the cathodic corrosion protection, a Cr (III) conversion layer and finally, the topcoat complement the system. Since the top-coat is the only layer in direct contact with the environment, it significantly influences the properties of the whole corrosion protection system. These include the resistance to chemicals and corrosion, the adaptation of the frictional force between the connecting element and the respective component, as well as other properties. The dynamic technical progress of the last 20 years in the automotive sector led to a higher quality requirement for the surface coating of connecting elements. The trends are weight reduction, higher corrosion protection and new material combinations. This has resulted in a harder materials, a higher thermal load and a more sophisticated control of the friction values, which can be tested with more advanced analytical methods. In parallel, demand for lasting decorative aspect is increasing.

It's not getting any easier for fasteners. However, with a new generation of specifically tailored top-coats for electro-coated fasteners, COVENTYA is ready to meet the future requirements of high performance automotive fasteners.

IMG3520komp reduced

At the end of June COVENTYA GmbH celebrated its 90th anniversary. Within the frame of the festivities, it was announced that Mr. Andreas Mühle will join the management team of Coventya GmbH as a managing director.

As Dr. Kühler has assumed the role of Executive Vice President Europe last year and is therefore responsible for the strategic and operational alignment of the European entities, Mr. Andreas Mühle was appointed to be managing director of COVENTYA GmbH as of 01.07.2017. He has been responsible for sales in the German-speaking countries since 2015 and has worked very successfully on the expansion of the sales organization in this time. In his new position, the successful development of sales will also be a main focus of his activity.

At the same time it was announced that Mr. Rainer Venz will leave the management of COVENTYA GmbH as of 01.10.2017. He will move to a position in the management of COVENTYA International GmbH in order to concentrate on the further development of the global KIM organization.                  


New EN offers highest selectivity for bi-injected parts in the field of Plating On Plastics

POP anouncement june 2 reduit6

Over the last decade, the demand for plated bi-injected parts has increased year after year.

Nearly every global automotive OEM, most notably in Europe and Asia, have such parts integrated in their interior design.  Examples of plated bi-injected parts are control knobs, push-buttons, ornamental frames for tachometers and many other parts too numerous to list

In addition to the increase demand for bi-injected parts, we have seen an increased need for high selectivity between the plateable and non plateable surfaces as well as a change in the material combinations.

A recent market study found significant differences in regards to selectivity between each plater and parts made in their moulding department. As a consequence, different platers use different processes and parameters in their plating line, often with a very narrow operating window.

COVENTYA offers a solution to this with our SILKEN METAL 701, a proven electroless nickel technology with the highest selectivity for various plastic combinations.

In addition to unrivalled selectivity, SILKEN METAL 701 has following advantages:

  • Broad operating window
  • Requires only one catalyst & accelerator for bi-injected parts standard parts
  • Ammonia free
  • Easily integrated into existing POP lines

One should not dismiss the importance of the ammonia free aspect of SILKEN METAL 701

Due to the high operating pH of ammonia based electroless nickel systems evolve very strong ammonia odors which require extreme ventilation.  Even under ideal circumstances, ammonia will be given off during pH adjustment and replenishment of the EN chemistry. Strong odor aside, ammonia fumes are significant irritants to humans and pose a serious safety risk.

SILKEN METAL 701 is completely odourless and operates under nearly the same parameters as the ammoniated versions currently in operation.  Immersion time, pH and temperature are all comparable with ammonia based electroless Nickel

In addition to the environmental benefits, SILKEN METAL 701 provides the highest selectivity on bi-injected parts, which are seen more and more in the interior of vehicles from most global automotive OEMs.

COVENTYA's SILKEN METAL 701 is installed in several major automatic POP platers across Europe and is delivering positive results for bi-injected parts all while creating a much more environmentally friendly workplace.
