SIKAFLEX 298 BLACK - DRUM 10 L
Sikaflex 298 is a slightly thixo-tropic 1-c polyurethane adhesive and sealant which cures on exposure to atmospheric humidity to form a durable elastomer.
Characteristics
- 1-C formulation
- Slightly thixotropic
- Elastic behaviour
- Contains no highly inflammable solvents
- Sound deadening
- Long open time
Application
- Suitable for bonding deck covering materials made from synthetic resins (except polyethylene and polypropylene), and for bedding-in and sealing of teak plank decking laid on top of the subdeck surface
- Suitable substrates include GRP, marine plywood, steel, aluminum sealed with an anti-corrosion coating (epoxy or polyurethane-acrylic based) and stainless steel
