Geomet 321 Description GEOMET® 321 alone or in combination with our range of topcoats passes the most severe corrosion cyclic tests. It protects parts from rust even after mechanical damage, such as stone chipping, thanks to its self-healing property. Benefits: Static friction coefficient > 0.20 Conductive and offers perfect galvanic properties to avoid bi-metallic corrosion in most of industrial assemblies (cast iron, carbon steel, and aluminum alloys). Excellent surface conditions for paints or additional coatings. Implemented via non-electrolytic application processes. This avoids the hydrogen embrittlement phenomenon that causes the cracking of metals. get a quote
