What SIKA TRANSFLOOR MARINE 352 is and why choose it
SIKA TRANSFLOOR MARINE 352 is a solvent-free, two-component polyurethane levelling system designed for marine decks. It is available in three versions: SikaTransfloor-352 ST (slightly thixotropic), SikaTransfloor-352 SL (self-levelling) and SikaTransfloor-352 VSL (highly self-levelling, very fluid). These systems are formulated to fill and level irregular metal or GRP substrates, creating smooth internal or external ship decks ready to receive an elastic adhesive finishing layer such as Sikaflex-298.
The product family combines low density, excellent workability, no shrinkage and easy sanding. All three versions are solvent-free and manufactured under ISO 9001 / 14001 quality systems and comply with International Maritime Organization (IMO) requirements, making them suitable for demanding marine applications.
Main features
- Two-component polyurethane system: bicomponent base for controlled curing and reliable mechanical performance.
- Solvent-free formulation: improves occupational hygiene and reduces emissions during installation.
- Three rheologies for different needs:
- SikaTransfloor-352 ST: slightly thixotropic for areas requiring limited flow.
- SikaTransfloor-352 SL: self-levelling for general deck levelling.
- SikaTransfloor-352 VSL: highly self-levelling, very fluid, easy to spread.
- Excellent working characteristics: easy to mix, apply and level.
- Low density: reduced weight contribution to the vessel structure.
- No shrinkage: stable layer thickness after curing.
- Easy to sand: allows fine adjustment of the finished surface where required.
- For interior and exterior decks: suitable for both internal and external marine applications.
- IMO compliant: products meet International Maritime Organization regulations for marine use.
