Sikaflex®-298
Slightly thixotropic bedding compound for marine applications
Sikaflex®-298 is a slightly thixotropic 1-component polyurethane adhesive which cures on exposure to atmospheric humidity. It is used for Teak deck bedding. Sikaflex®-298 meets the regulations set out by the International Maritime Organization (IMO).
- Long open time
- Slightly thixotropic
- Sound deadening properties
Areas of Application
Sikaflex®-298 is suitable for bonding deck covering materials made from synthetic resins (except polyethylene and polypropylene), and for bedding-in of teak plank decking laid on top of the sub deck surface. Suitable substrates include GRP, marine plywood, steel, aluminum sealed with an anti-corrosion coating (epoxy or polyurethane-acrylic based) and stainless steel. Sikaflex®-298 has a longer skinning time as the Sikaflex®-298 FC version and might be used where elevated temperature and/or higher humidity are expected. Sikaflex®-298 is suitable for experienced professional users only. Test with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.
