U-Seal 550FC

High thixotropy, fast curing one-part polyurethane elastic adhesive and sealant, which is PVC-free and odorless

U-Seal 550 FC is a one-part, very fast curing, polyurethane elastic adhesive and sealant designed for industrial assembly and car body construction and repair. Thanks to its thixotropy and outstanding body meets most demanding requirements in sealing and bonding industrial applications. Thanks to its special formulation, it is completely odorless. The product can be easily brushed and tooled in order to match the original mark and give first equipment appearance to the seam. Areas of application U-Seal 550 FC is suitable for seam sealing like welded seams, lap panels in all internal vehicle bodywork and painted sheet metals which includes the reproduction of original brush marks, simple and demanding bonding as well as for vibration reduction and sound deadening measures in car body repair and car body construction. Suitable substrates are metals, metal primers and paint coatings (2-c systems), painted plastics.
