Latest Patents

Van Der Aar holds a patent for a method of rubber to metal bonding using silane coupling agents. This patent details how the adhesion of rubber to metals such as aluminum, stainless steel, mild steel, and brass can be effectively achieved. The process involves applying an organofunctional silane and a non-organofunctional silane to the metal surface. The preferred organofunctional silane is a vinyltrialkoxysilane, while the non-organofunctional silane is typically an alkoxylated substituted alkyl silane. These silanes are partially hydrolyzed and provided in an ethanol/water solution. The bonded joints formed through this method can withstand fuel degradation tests, making them suitable for applications where metal and rubber surfaces are exposed to fuels, oils, and organic solvents.
