At 3RM, we stand for maximum precision and reliability when it comes to chromating and passivating metal surfaces. Our processes, including Bonderite M-NT 400 (formerly Alodine) and surtec 650are specially designed to give components made of aluminum and other metals maximum corrosion protection, electrical conductivity and optimum adhesion properties.
As a partner to the metalworking industry, we know that surface treatments must not only protect, but also precisely fulfill functional requirements. Our focus is on process reliability, consistently high quality and on-time delivery.
Stronger together: Our connection with Diener & Rapp
Together with Diener & Rapp, we form a group of companies specializing in the coating of aluminium. While chromating and passivation carried out by 3RM primarily cover technical functions such as corrosion protection and electrical conductivity, anodizing by Diener & Rapp also focuses on decorative design.
Thanks to our close partnership, we as a group offer a wide range of surface solutions: from functional-technical coatings to high-quality, colored anodized coatings. This puts us in an ideal position to meet the high demands of our customers in the metalworking industry.
