Anti-adhesive handles

CIDETEC have been working with EGOKI HANDLES on developing new anti-adhesive finishes for metal parts for a number of different applications.

The aim of the project has been to achieve product enhancement, specifically to add a transparent and anti-adhesive protective coating to the TIRADORES EGOKI (EGOKI HANDLES) company range of decorative finishes for their metal.
From a technical perspective, two alternatives were initially put forward for obtaining organic protective coatings for zamac (Zn+Al+Mg+Cu alloy) handles: firstly, organic coatings by means of electropolymerisation and secondly, the application of a protective varnish with anti-adhesive characteristics, the latter being precisely the one which gave the desired results.

The key aspects worked on were the optimum adhesion of the varnish to the handle, getting good end properties for the coating and devising a method for the application which was useable on an industrial scale. To this end, new families of products were studied and which were based on special organic-inorganic hybrid varnishes with anti-adhesive properties, and which have recently appeared on the German market.

Apart from this joint work, CIDETEC is researching this line of work using self-assembly methods for coating with nanolayers and its application in surface modification of metals, providing them with both anti-adhesive properties as well as other surface properties of interest: coatings that promote adhesion or protection against corrosion, with antibacterian or bioactive properties.
