What SIKA TRANSFLOOR MARINE 352 is and why choose it
SIKA TRANSFLOOR MARINE 352 is a two-component polyurethane levelling system designed for internal and external marine deck applications. It is available in three versions: slightly thixotropic (SikaTransfloor-352 ST), self-levelling (SikaTransfloor-352 SL) and highly self-levelling with very high flow (SikaTransfloor-352 VSL). All three systems are solvent-free fillers and levelling compounds developed to correct irregularities on metal and GRP decks in a single operation, providing a smooth, low-density substrate ready to receive elastic adhesive layers.
The product is manufactured under ISO 9001 / 14001 quality assurance systems and complies with International Maritime Organization (IMO) regulations, making it suitable for demanding shipbuilding environments.
