Exera® Bondable Coatings
Bondable coatings can be applied to bare wire or as a second coat over the top of any of the insulations that are offered. The amount of coating applied can be standard NEMA or JIS build or thinner amounts as required.
If a special coating or insulation is required Sandvik will work with you to develop a process for its use. Sandvik has, for example, developed low out-gassing, high-temperature, self-bondable coatings specifically designed for the hard disk drive industry to reduce contamination and deliver good resonance performance.

Metallic coatings
Sandvik provides several types of metallic coatings such as anodizing, electroplating and electropolishing. As a standard, Sandvik offers gold-plated wire, nickel-plated wire and silver-plated wire, but also other types of electroplating can be manufactured on request. Additionally, Sandvik works with cladding and cladded alloys.
