MNI Selects VICOTE™ Coatings

Published on 2006-05-18. Author : SpecialChem

Thornton Cleveleys, England -- Metallisation Nord Industrie (MNI), based in Lille, France, has selected VICOTE™ Coating as a key element of its new formulation named SkidCoat. An innovative polymer-ceramic wear resistant coating, SkidCoat is designed to meet specific requirements of the food processing industry.

SkidCoat is a polymer-ceramic compound that can be thermally sprayed onto a pre-treated substrate to provide a hard layer of 1300 Vickers combined with excellent friction and non-stick properties. VICOTE Coatings provides SkidCoat with excellent high temperature performance, wear-resistance, and excellent durability.

The key properties that VICOTE Coating provides SkidCoat are: continuous use at temperatures up to 260°C and retention of mechanical properties at elevated temperatures; exceptional wear and abrasion resistance; chemical resistance to hydrocarbons and aggressive cleaning agents; good electrical performance, as well as FDA compliance for food contact. The new VICOTE Coating product range is based on VICTREX® PEEK™, the linear, aromatic, semi-crystalline polymer widely regarded as one of the highest performing thermoplastics in the world.

The main challenge for MNI was to mix and spray the VICOTE Coating with carbides or ceramics without degrading the characteristics of the product when exposing it to high temperatures employed in thermal spraying.

“The SkidCoat formulation allows coating layers with thicknesses of several hundreds of microns combining hardness, impact and wear resistance, with excellent friction and non-stick properties,” said Patrick Giffard, Founder and Managing director of MNI. “With a flexural strength above 325 MPa, SkidCoat can replace the existing composites coatings commonly used in these applications, delivering much higher impact and flexural strength.”

SkidCoat is totally hydrophobic and is particularly suitable for butterfly valves, transfer rollers for paper, cardboard and plastics, calendering rollers for sheet metal and all types of food industry equipment.

Equipped with very large robotically controlled thermal spraying equipment, MNI is able to treat parts of few centimeters up to large rollers of 6 meters length. This process for the surface treatment of tools and tool-machines has already been successful applied in numerous applications.
