Safe, high-performance coatings for food contact

    IHI Ionbond obtained United States FDA food contact (TOR) approvals for Ionbond™ coatings after a strict evaluation which included tests of biocompatibility, migration, wear and dissolution in various environments.

    The Ionbond™ food contact coatings can be deposited by various technologies at temperatures ranging from 100°C to 950°C depending on coating choice and substrate temperature resistance. The coatings are used and recommended in food processing due to their outstanding mechanical and tribological properties:

    • Abrasion resistance, i.e. reduced wear
    • Anti-sticking, i.e. food tends to stick to the tools and machine components during processing. Pasta’s, dough, candy
    • Ideal for systems with poor, dry, lubrication, when not allowed to use oil. Often stainless steel is running against stainless steel, like in liquid pumps for beer and milk, transportation, etc

    The coating thickness can be adapted from 1 to 10 micrometer allowing our customers to have the most suitable coating specification for each application covering various substrate materials such as a broad range of steels among others. 

    Among the broad range of Ionbond coatings, the best performance and safest solution for your application have the following properties:

    Ionbond™ 01 TiN, probably the best known PVD/CVD coating, golden color, high hardness and high abrasion resistance, it remains a great value specially for food cutting tools.

    Ionbond™ 30 CrN, silver/metallic colour coating with high ductility and high hardness; It has a great resistance to deformation without cracking making it suitable for food contact components and flexible cutting blades.

    Ionbond™ 42 DLC, black color multilayer coating, low friction coefficient, high scratch resistance and load carrying capacity makes this multilayer DLC suitable for food contact applications under high mechanical pressure to avoid food surface-sticking even without lubrication.  

    Ionbond™ 43 ADLC, exhibits black color, smooth surface, with high hardness and high deformation capacity without cracking, it makes it especially suitable for anti-sticking applications even without lubrication as for example flexible cutting blades and food contact components.

    The coating thickness can be adapted from 1 to 10 micrometer allowing our customers to have the most suitable coating specification for each application covering various substrate materials such as a broad range of steels among others.
    In terms of application-benefits, the Ionbond™  coatings increase productivity in food processing by substantial increase in surface performance of components and tools for:
