Chemetall, the surface treatment supplier that is now a business unit of BASF’s Coatings division, has introduced Jurblami application nozzles for high-quality, fast and reproducible sealing operations.The nozzles allow manufacturers to significantly reduce the time required to apply the sealant to the rivets on aircraft fuel tanks and fuselages. The specially shaped nozzles are suited for the application of Chemetall’s Naftoseal polysulfide sealants. The Naftoseal portfolio offers a wide range of medium and low-density, chrome-free, fast-curing, multi-purpose aircraft sealants. With their bell-shaped heads, the Jurblami application nozzles encapsulate the rivets and nuts, creating an effective mold for the sealant coating. This provides high corrosion protection for those parts exposed to water, corrosive oils or sudden temperature changes. As the exclusive global distributor for the Jurblami products, Chemetall can offer the application nozzles in different sizes to fit various dimensions of nuts and rivets, enabling fast and efficient sealing operations. In addition to rivet sealing, the application nozzles can also be used for the sealing of drilling holes and fillets.
