Adhesive for Expanded Polystyrene Tytan EOS 750 ml – foam board glue, construction adhesive

Tytan EOS 750 ml is a construction adhesive designed for bonding expanded polystyrene (EPS) and foam insulation boards. Supplied in a 750 ml cartridge, this adhesive is formulated to provide secure adhesion to common substrates used in external and internal insulation systems, and for fixing decorative polystyrene elements. The product is intended for use in building applications where foam-to-surface bonding is required, offering a practical solution for thermal insulation installation and lightweight panel attachment.

Advantages

The adhesive offers reliable bonding strength for expanded polystyrene and similar foam materials while remaining easy to apply from a standard cartridge gun. Its formulation provides good initial tack and enough open time to position insulation boards before the bond develops. Because it is developed specifically for foam boards, it minimises material damage or melting that can occur with solvent-based adhesives and supports a clean installation process on vertical and horizontal surfaces.

Suitable for

• Fixing expanded polystyrene (EPS) insulation boards to masonry, concrete and render.
• Installing foam insulation in internal and external wall systems.
• Bonding decorative polystyrene mouldings and lightweight foam panels.
• General foam-to-surface bonding where a cartridge-applied adhesive is required.

When it may not be suitable

This adhesive is formulated specifically for expanded polystyrene and similar foam products; it may not provide optimal performance on non-porous, highly flexible or extremely heavy substrates where mechanical fixing is required. It is not intended as a structural adhesive for load-bearing connections or for bonding materials that are sensitive to the adhesive chemistry without prior compatibility testing.

Key specifications

• Form: cartridge-applied construction adhesive, 750 ml cartridge.
• Compatible materials: expanded polystyrene and similar rigid foam insulation boards.
• Application method: manual or pneumatic cartridge gun.
• Typical uses: external and internal insulation systems, decorative foam elements.
• Working conditions: suitable for application on common building substrates such as masonry, concrete and rendered surfaces.

How to use

Prepare substrates by ensuring they are clean, dry and free of dust, grease or loose particles. Cut the cartridge tip and attach a suitable nozzle, then apply the adhesive in beads or dots according to the insulation board manufacturer’s recommendations. Press the EPS board firmly against the substrate and align within the adhesive open time. For larger panels or higher wind loads, combine adhesive dots or beads with mechanical fasteners as required. Allow the bond to cure before applying finishes or mechanical loads, following standard curing times and site conditions.

What to consider before purchase

• Confirm compatibility with the type of foam insulation you plan to use (rigid EPS or similar).
• Check substrate condition and whether additional mechanical fixing will be necessary for heavy or exposed installations.
• Ensure you have the correct application gun and nozzle for a 750 ml cartridge.
• Verify required working temperature range and ventilation for the application area.

Usage recommendations

For best results, follow the insulation producer’s layout for adhesive pattern and allow sufficient curing time before applying render or other finishes. When installing external insulation at heights or in windy locations, use combined adhesive and mechanical fixings to meet local building regulations and ensure long-term stability.
