Fastener Applications – Holding Things Together
Fasteners, nuts, bolts, screws, clamps, etc. – they hold things together and their finishes are critical to this function. Fasteners are coated to protect against corrosion or to achieve special properties. Industries such as automotive, construction or electronics have specific requirements for fasteners and it is Atotech's challenge to match all those specific needs. To make sure that individual friction values are met, Atotech offers lubricants, integrated within a sealer or as a separate step.
The automotive industry is the largest fastener consumer. Automotive fasteners are a very sophisticated application for corrosion protection coatings and have to meet specifications. Atotech offers a full range of products for electrolytic deposition as well as for dip spin applications meeting global OEM requirements –
Coatings applied in the construction industry have to be Cr(VI)-free, resistant to different wood preservatives and have to offer high lubrication performance for high speed screwing or self-drilling properties. Modern designs require also an attractive appearance. Atotech's innovative base and top coats, available in many colors, meet these needs. To match the requirements of the electronic industry, Atotech provides – in compliance with the WEEE and RoHS Directives – Cr(VI)-free passivates.
