SURFACE Campus will offer around 75 different lectures in hall 4. Let the stories inspire you. Take master classes to put theory into practice. And present your issues to experts during one of the consultation moments. The congress hall is where you’ll be the first to hear about the latest developments. So be there, if you want to stay up-to-date.
AD Chemicals, together with steel construction company Hollandia Infra have been nominated for the ION Borghardt 2018 award.
The ION Borghardt Award is the acknowledgement for innovation and sustainability. Once every two years, the Ministry of Economic Affairs awards one company that shows how vital sustainability and innovation are in the surface treatment industry.
An independent jury, selected by Stichting Borghardt examines the entries and nominates the ten best ideas to be exhibited at the trade show. The winner will be announced on Tuesday, 13 November 2018. The award show marks the kick-off of SURFACE Campus.

Last week our AD Chemicals Business Unit Manager gave a speech at the Hendor Pumps Technical Conference 2018 about the importance of collaboration between partners in the supply chain for chemical metal surface treatment. The market standard can only be exceeded if applicator, suppliers and end customers join forces and have a common vision on quality. Interested in our approach? Chemicals@adinternationalbv.com
AD Chemicals has more than 40 years of experience in developing, manufacturing and worldwide supply of a wide range of metal surface pre-treatment chemicals. Pre-treatment is an essential process on metal products that are coated to provide a durable and attractive finish. AD Chemicals draws knowledge and expertise from across the range of AD International chemical disciplines to provide customers with the best possible advice from a leader in its field. This results in robust and reliable processes that are efficient and cost effective.
AD is known in the market for its innovative and market exceeding chromium(VI)-free conversion coatings that meet or outperform hexavalent based treatments. Products are marketed under the “PreCoat” brandname. Many surface treatment operations desire certification by industry organizations, especially when applied to new and technically driven products. Customers have come to rely on AD Chemicals to assist in or lead the certification process. All products meet or exceed current market standards such as GSB, Qualicoat, Qualisteelcoat and MIL.
Latest innovations:
PreCoat Z31: Cromium(VI)-free multi-metal conversion coating, tailored to the high demands for duplex coating applicators (powder coating over hot-dip galvanized steel). Only European alternative that performs equal to chromium(VI). Meets the Qualisteelcoat and GSB standard. Winner of 2016 Dutch Innovation Award for surface treatments. Also Qualicoat(A-119) approved for aluminium.
PreCoat TVL: Multi-metal (iron, steel, galvanized) passivation to upgrade the iron phosphating process, enables corrosion protection over 1000 hours NSS. Exceeds Qualisteelcoat standard and has a Qualicoat (A-095) approval for aluminum.
PreCoat A34: Based on a high-tech aerospace technology. Chromium(III) based conversion coating that enables bare metal corrosion protection in combination with excellent paint adhesion and corrosion resistance, Qualicoat (A-126) approved.
PreCoat CF: Complete chromium-free conversion coating for aluminium. GSB and Qualicoat (A-021) approved. No rinse system.

Following close cooperation with a leading chemicals supplier, Tata Steel has launched Prime Lubrication Treatment (PLT), a so-called booster lubricant, consisting of a thin coating that is applied in the galvanising line prior to applying the conventional oil layer.
The combination of PLT and oil is claimed to provide a superior lubrication system that improves processing of hot dip galvanised GI steels for exposed automotive panels. It induces a lower and more stable friction during pressing and is particularly suitable to support manufacturing of panels such as fenders, doors and body sides to a high surface quality. The new lubricant extends Tata Steel’s Serica and Full Finish premium offering for outer panels.
The unique formulation of PLT – developed in conjunction with Netherlands based Coil Coating Technologies (CCT), part of the AD International group – offers an improved press performance of GI steels when compared to those treated with standard conventional oil. It enables manufacturers to move away from electro-galvanised (EG) steels towards the more cost-effective GI-coating. When compared to the common process, PLT enables a smoother pressing operation with reduced maintenance costs and therefore a higher production yield and has been designed not to disturb subsequent manufacturing processes like resistance spot welding (RSW) and adhesive bonding.
Consisting of a very thin, organic layer, PLT induces a lower friction coefficient that stays more stable over subsequent press cycles in comparison to GI material treated with only a standard oil. PLT is completely removed in the cleaning bath towards the end of the process, leaving no residue behind. It is a harmless, environmentally friendly substance, and it is entirely sustainable. It will initially be available for products from 0.6mm to 1mm thick and from 900mm – 1,830mm wide, with plans in place to extend the width to 2,020mm.
“One of the main values of using PLT is its induced friction coefficient which is consistently low to reduce tool wear and pollution to acceptable low levels for efficient manufacturing processes. This brings the long-cherished wish of going to 100% hot dip galvanised material for the exposed car body panels a decisive step closer,” said Basjan Berkhout, marketing manager, body in white at Tata Steel.

Aluminium alloys are extensively used in space programs for both structural and non-structural applications. As well known, the corrosion resistance of these alloys is quite limited and anticorrosion treatment is needed.
The most used treatment currently used for improving the corrosion resistance of aluminium alloys are usually chromate (CrVI-based) conversion coatings (CCC). Due to the high environmental impact of these compounds, the REACH Regulation of the European Union decided to limit/restrict the use of hexavalent chromium. A sunset date of mid-2017 has been already set.
For the time being many chromate-free alternative products are available but they have found to be significantly inferior in terms of corrosion protection performances with respect to the chromate options. In this regard there is a great need to develop high performance hexavalent chromium-free anti-corrosion coatings with low environmental impact and conformity with the EU regulations.
The European Space Agency (ESA) is currently involved in a TRP contract with Instituto de Soldadura e Qualidade (ISQ) that is currently on-going. The objective of this study is to evaluate the anticorrosion behaviour of the different alternative pre-treatments applied to the most used aluminium. The outcome of this activity will be the identification and the optimization of the most promising anticorrosion pre-treatment.
Several commercial Cr(VI) free processes were applied onto aluminium alloys (2024-T3 and 2024-T81) used in the construction of ESA spacecraft, in order to investigate their anticorrosive properties compared with Alodine 1200, a widely used conventional CCC. One of these commercial processes (PreCoat A32) presented good anticorrosion performance, even better than Alodine 1200 and these results are presented in this paper.
Salt spray resistance is included in the testing program as well as metallurgical coating evaluation that include microscopy (SEM) observations before and after testing and electrochemical impedance spectroscopy (EIS), in order to evaluate surface and microstructural modifications due to degradation mechanisms. Further studies must be performed with the this promising alternative, modifying application parameters, in order to achieve improved corrosion protection efficiency.
