Schlötter’s first virtual fair
has generated a strong interest

How to get close to your customers in times of social distancing: After the cancellation of the Surface Technology Germany in Stuttgart due to Corona, Dr.-Ing. Max Schlötter GmbH & Co. KG decided to organise a virtual trade fair instead from 16-18 June 2020 to inform its customers and sales partners about new products. During a tour of the virtual exhibition stand visitors could look at various digital exhibits which were just a mouse-click away. The exhibits included Copper SLOTOCOUP PRT 2200, a reverse pulse plating process, which was developed for through-hole plating of printed circuit boards with very high aspect ratios which are used, eg., for manufacturing server boards, Pickle Degreaser SLOTOCLEAN BEF 1790 which reduces the risk of production-related hydrogen embrittlement, and various processes for direct metallisation of plastics.

Schlötter’s plant engineering division exhibited a new high-power contact and an optimised zinc dissolving station (also filed for patent). For the first time, Schlötter also presented Schlötter Smart Services, the company’s new digital solution for the Internet of Things (IoT). Schlötter Smart Services consist of two main features: online plant monitoring and process monitoring via a web-based application. In doing this, important parameters such as the plant output or the temperature and pH value of the electrolytes being used can be monitored automatically.

The Italian company Italtecno, with whom Schlötter has recently concluded a cooperation agreement, was also present at the virtual trade fair.

Thomas Haberfellner, Head of Sales and Service at Schlötter, drew a positive conclusion: “Overall, we were very pleased with the attendance, as we were able to welcome many hundreds of visitors at our booth. Our webinar lectures, which were a first for Schlötter, were particularly popular. The webinars resulted in many interesting discussions and in-depth talks as well as appointments for individual webinars”.

Extensive webinar program
The virtual trade fair also included several webinars. Following webinars are also availabe in English:

  • On the verge of series production– SLOTOSIT KM 3000 – metallisation of special plastics
  • 3 in 1 – the solution for MSAP and SAP – SLOTOCOUP SF50
  • SLOTOCOUP PRT 2200 – high aspect ratios with the new Reverse Pulse Plating System for VCP and SVP systems
  • Pickle degreaser of the next generation – SLOTOCLEAN BEF 1790 – more process safety regarding hydrogen embrittlement during pickling
  • Time, energy and resources – Focus on economy and CO2 savings: High-performance plating of zinc-nickel in the alkaline barrel system SLOTOLOY ZN 210 VX
  • Boric acid-free acidic high-gloss zinc bath – SLOTANIT BSF 1660
  • Time, energy and resources – focus on economy and CO2 savings: KOH-based zinc system ZINCASLOT ZA 2390 – fast and with remarkable metal distribution
  • Schlötter Smart Services Digital solutions for electroplating
  • Time, energy and resources – focus on economy and CO2 savings: High Temperature Anodising Process. Anodising Additive WM 80 L – energy savings (lower voltage and less cooling)
  • Nickel free cold sealing for architectural and decorative applications and Superseal for automotive application

Schlötter is granted patent
for SLOTOLOY ZN VX technology

“Method for the galvanic deposition of zinf and zinc alloy layers from an alkaline coating bath with reduced degradation of organic bath additives” – this is the title of European patent EP 3481976, which was granted to Dr.-Ing. Max Schlötter GmbH & Co. KG on 15 April 2020.This somewhat lengthy title refers to Schlötter’s SLOTOLOY ZN VX technology, which was awarded the Innovation Prize of the state of Baden-Württemberg in 2018. The SLOTOLOY ZN VX technology is the basis for two zinc-nickel alloy baths SLOTOLOY ZN 80 VX (for rack applications) and SLOTOLOY ZN 210 VX (for barrel applications). Both electrolytes feature a significantly reduced formation of cyanides and a lower consumption of organic additives compared to conventional alkaline zinc-nickel electrolytes. At the same time, the bath voltage is significantly reduced and energy efficiency is significantly increased.

The VX systems offer  following advantages:

  • Efficient use of resources: The overall consumption of chemicals is lower, since significantly less organics are degraded. Due to the lower cyanide content of the electrolyte, a lower nickel concentraction is required. Less raw materials are required to operate the electrolyte, which has a positive effect on consumption costs. Due to the lower bath voltage and less needs forcooling, the overall power consumption is reduced by up to 30%.
  • Higher productivity: The current efficiency increases by 5-10% for barrel applications and by approx. 5-7% fro rack applications. Due to the higher current yield, the deposition rate is simultaneously increased by approx. 5-20%, thus the output of electroplating plants can be increased by up to 30% (for barrel applications).
  • Strengthening of environmental and climate protection: The significant energy savings in plating, the faster deposition rate and the savings in organic additives not only lead to an increase in productivity, but also to a significant reduction in cyanide and wastewater volume per plated parts and a reduction in energy and chemical consumption in wastewater treatment. The new process thus represents an active contribution to environmental and climate protection.

Meanwhile, both SLOTOLOY ZN VX 80 and SLOTOLOY ZN VX 210 have performed tremendously well in practice for about three years and are in use worldwide.

Schlötter announces cooperation with Italtecno srl.

In the future, Schlötter will cooperate with the Italian specialist Italtecno srl. in Modena in the field of surface treatment of aluminium and thus expand its competence in the field of surface treatment.

Italtecno was founded in 1974 and specialises in the research and development of surface treatment technologies for aluminium and its alloys. In the early 1980s Italtecno expanded its market for chemical products, machinery and systems outside Europe and in many different sectors (aluminium for use in the building and construction, automotive and aerospace industries, and for decorative, mechanical and other industrial purposes) and in 1983 sold an important licence for special anodising technologies to Lockheed, thus making its debut on the American market. Italtecno then opened subsidiaries in Brazil, India and the Far East, as well as offices for agencies, sales and technical service in 25 different countries worldwide. With internationally recognized experts and researchers, Italtecno is one of the key partners for all users in the industry. Italtecno, based in northern Italy, works in close contact with customers to develop tailor-made technological solutions and provide post-sales technical support wherever an Italtecno customer is located in the world. This philosophy perfectly matches the product and service philosophy of Schlötter and forms the basis for a good future partnership.

Schlötter will expand its portfolio of galvanic specialty chemicals by the anodising portfolio and the know-how of Italtecno and thus offer sales and service for processes for aluminium surface treatment in the future. Due to a very close cooperation also in the development area, tailor-made customer solutions for aluminium surface treatment can be offered in this way, as known from Schlötter’s electroplating area.

At the virtual trade fair, which took place in June, attendees got a comprehensive picture of the new product portfolio on the special galvanic processes of Schlötter and the new processes for aluminium surface treatment of Italtecno. During this period, our sales teams from the fields of technology and electroplating chemistry, as well as the specialists from the Research & Development department, were on hand to discuss and explain the various processes. We welcome your questions and suggestions.
