Polyurethane Sealant Adhesive Tytan PU 40 FC 300 ml — grey

Tytan PU 40 FC 300 ml is a grey polyurethane-based sealant and adhesive designed for joint sealing and bonding in construction and repair applications. Supplied in a standard 300 ml cartridge, this product combines elastic joint filling with dependable adhesion to a variety of common building substrates. Its formulation is intended to withstand outdoor exposure and typical weathering, making it suitable for tasks such as window and door installation, façade repair and general sealing operations where a flexible, durable joint is required.

Advantages

The polyurethane composition provides good adhesion to concrete, brick, wood, metal and many plastics without the need for a primer in some applications. Elasticity of the cured sealant allows for movement accommodation in joints and prevents cracks under thermal or mechanical stress. The grey color integrates with neutral building finishes and helps achieve a discreet finish for visible joints. The cartridge format is compatible with standard caulking guns for controlled application.

Suitable for

• Sealing and bonding around windows and doors
• Façade repairs and filling expansion joints
• General indoor and outdoor sealing where elasticity is required
• Bonding of building materials such as concrete, brick, wood and metals

When it may not be suitable

This polyurethane adhesive-sealant may not be suitable for applications requiring paintability with certain water-based or specific high-gloss coatings without prior testing, as some polyurethanes can affect paint adhesion. It is not intended for use on surfaces that will be continuously submerged or for sealing potable water systems unless the product documentation explicitly states such approvals. Surfaces contaminated with oil, grease or loose particles will reduce bond performance and require proper cleaning before application.

Key specifications

• Formulation: polyurethane-based adhesive and sealant
• Packaging: 300 ml cartridge for use with standard caulking guns
• Color: grey
• Curing behaviour: elastic after curing to accommodate joint movement
• Application: suitable for indoor and outdoor use; adheres to common building substrates such as concrete, brick, wood and metals

How to use

Prepare the joint by removing dust, loose material, oil and grease. Cut the cartridge tip to the required bead size and attach the nozzle; load into a compatible caulking gun. Apply the sealant evenly into the joint under steady pressure to ensure full contact with the substrate. Tool the bead within the product's skin formation time to achieve the required profile and adhesion. Allow the sealant to cure undisturbed according to ambient temperature and humidity; ensure adequate ventilation during curing. Follow any safety instructions on the packaging and dispose of empty cartridges according to local regulations.

What to consider before purchase

• Verify compatibility with the specific substrates and any paint or coating systems to be used
• Confirm required joint width and depth to ensure one cartridge covers the planned work
• Check temperature and humidity conditions for storage and application
• Determine whether a primer is needed for certain porous or difficult substrates

Usage recommendations

For best results, apply at recommended temperatures, clean and dry substrates thoroughly, and tool the sealant to ensure full contact. Test adhesion and paintability on a small area if the joint will be painted or finished. Use personal protective equipment when handling cartridges and observe ventilation requirements during application and curing.
