Most promising innovation for grit blasting ; Combining blasting and chemical pretreatment

One of the most important factors influencing paint adhesion and corrosion resistance is surface preparation. To ensure optimum performance and long-term environmental resistance, metal substrates must be free of organic and inorganic contaminants. To prepare a surface one can basically choose between 2 options, blasting or chemical pretreatment.

 

  1. Mechanical/Blasting – Abrasive particles (sand, grit or metal oxides) are projected against the surface with a stream of air. The character or quality of the treatment is affected by duration of the blast; shape and size of the blasting media; particle velocity; and the hardness, porosity and other substrate properties. A metal surface treatment of blasting ensures a uniformly cleaned surface and good paint adhesion but lacks corrosion resistance on the substrate.

 

  1. Chemical processes, on the other hand, utilize organic and inorganic chemicals to achieve two reactions: • Dissolve, suspend or eliminate soils and surface contaminants. • Convert metal surfaces from the essentially free metallic state into metallic compounds.New option: Combining the worlds of blasting and chemical processingCurrently, AD Chemicals, a subdivision of the Dutch AD, International launches a revolutionary new product on the global grit/sand blasting market. This product is called PreCoat F31/20 suitable for the treatment of substrate steel and PreCoat Z31/20 for the substrates aluminum and galvanized steel. PreCoat is a chemical treatment applied directly after grit/sand blasting or metallization (also referred to as metal spraying). This product portfolio is the result of an R&D trajectory of more than 8 years. PreCoat F31/20 and Z31/20 significantly improve the quality of sandblasted or metallized products.

It has two main benefits; by applying the product directly after grit/sand blasting, a conversion layer is created that substantially improves the adhesion of the painting system (suitable for wet painting and powder coating) and significantly enhances the corrosion-protection resistance properties of the paint system as a whole. The application procedure of PreCoat is very easy and can be easily integrated in every business processes.

The innovative aspect of these products is that it combines the worlds of grit/sand blasting and chemical pre-treatment.

PreCoat F31/20 and Z31/20 are based on PreCoat Z31, a product that won the Dutch Innovation Award for surface treatment, ION Borghardt Award 2016.

AD Chemicals is introducing this product on the worldwide market. The first user responses are very promising. A large blasting company in the Netherlands stated: “With this product I am able to improve to overall quality of my products and therefore offer my customers more value. It is a tool to distinguish myself in a competitive market place”

Besides that the responses from our agents in Spain and the UK are very promising.

As products are better protected against corrosion, the product lifetime increases and thereby lowers the ecological footprint. See below the pictures after 500 hours salt spray testing where the difference is demonstrated between the regular automated grit blasting process and the grit blasting process with PreCoat treatment.

Innovative chromium (VI)- free processes (AD Chemicals/Weert Group)

 

PreCoat Z31 for galvanized steel: First in Europe

AD Chemicals (chemical supplier) and Weert Group (galvanizer and powder coating applicator) are introducing an innovative chromium (VI)- free pretreatment system prior to powder coating on galvanized steel (Duplex-system). Weert Group is the first galvanizer in Europe to implement this new technology that complies with both the GSB and Qualicoat (Approval No. A-119) standard.

For making this innovation possible, there has been a joint research and development trajectory of more than 8 years. The uniqueness of the PreCoat Z31 pretreatment lies in the fact that it is a 1-on-1 replacement for chromium (VI), meaning that all the qualitative properties are sustained (corrosion protection, paint adhesion, passivation). This results in a corrosion protection and paint adhesion of more than 2000 hours of NSS, a performance to be proud of. The expectation of AD Chemicals and Weert Group is that this new system will become the (global) market standard in chromium (VI) free pretreatments on galvanized steel.

 

More innovations from AD Chemicals: PreCoat F31/20 and Z31/20 for grit blasting

AD Chemicals launches a revolutionary new product on the global grit/sand blasting market. Namely, PreCoat F31/20 suitable for treatment of steel and PreCoat Z31/20 for aluminum and galvanized steel. PreCoat is a chemical treatment applied directly after grit/sand blasting or metallization(also referred to as metal spraying). It has two main benefits; by applying the product directly after blasting, a conversion layer is created that substantially improves the adhesion of the painting system (suitable for wet painting and powder coating) and significantly enhances the corrosion-protection resistance properties of the paint system as a whole. The application procedure of PreCoat is very easy and can be integrated in every business process. Furthermore it is developed in compliancy with the Qualisteelcoat, Qualicoat and GSB quality standards. The innovative aspect is that it combines the worlds of mechanical and chemical pre-treatment, enabling a longer product lifetime.

AD Chemicals en Weert Groep winnen de ION Borghardt Award 2016

Tijdens de opening van Surface 2016, de vakbeurs voor oppervlaktetechniek, is de ION Borghardt Award 2016 uitgereikt aan AD Chemicals in partnership met Weert Groep. Ze hebben een innovatie geleverd op het gebied van chroom(VI)-vrije voorbehandeling op verzinkt staal voor poedercoaten en natlakken.

Deze innovatie won de prijs omdat zij volgens de jury over de gehele breedte van de gestelde criteria op het gebied van ‘people-planet-profit’ bijzonder hoog scoort. “Niet alleen marktbelang en ketenoptimalisatie, maar ook zaken als maatschappelijk verantwoord ondernemen, kostenreductie, arbeidshygiëne en ontzorgen van de klant zijn nadrukkelijk meegewogen in ons oordeel”, aldus Arjan Mol namens de jury.

Chroom(VI)-vrije voorbehandeling op verzinkt staal Weert Groep en AD Chemicals hebben de afgelopen zes jaar een intensief partnership opgebouwd om tot een chroom (VI)-vrije voorbehandeling voor poedercoating (Duplex systeem) te komen die qua eigenschappen op het vlak van corrosiebescherming en lakhechting vergelijkbaar is met het toxische chroom (VI). Uitgebreide laboratorium- en praktijktesten, zoals het machubad (versnelde corrosietest) en de zoutsproeitest geven minimaal dezelfde resultaten en zodoende worden alle goede eigenschappen behouden. De oplossing laat tevens zien dat intensieve ketensamenwerking leidt tot nieuwe innovaties.
