Tytan polyurethane adhesive-sealant PU 40 FC 600 ml — gray, multifunctional construction sealant

Tytan PU 40 FC 600 ml is a gray polyurethane adhesive-sealant designed for a wide range of construction and repair tasks. It combines adhesive strength with elastic sealing performance, allowing it to bond and seal joints, gaps and cracks on commonly used building substrates. The product is suitable for both indoor and outdoor applications where a durable, weather-resistant and load-bearing seal is required.

Advantages

The formulation provides strong adhesion to many materials while maintaining elasticity after curing, which helps accommodate movement in joints and prevents cracking. Weather resistance and durability make it suitable for exterior use, and the cartridge format supports application with a standard caulking gun for controlled dispensing. The gray color offers a neutral finish that is compatible with various construction elements.

Suitable for

• Sealing expansion and connection joints in facades and claddings
• Bonding and sealing window and door frames to surrounding structures
• Filling gaps and cracks in concrete, masonry and some building boards
• Indoor sealing tasks where a durable, elastic joint is required

When it may not be suitable

The polyurethane adhesive-sealant may not be suitable for continuous immersion in water or for applications requiring immediate paintability with all paint types; some paints may require a primer or a fully cured surface. It can react with certain plastics or bituminous surfaces—compatibility testing on small areas is recommended before full application.

Key specifications

• Base: polyurethane
• Color: gray
• Volume: 600 ml cartridge
• Function: adhesive and elastic sealant for bonding and joint sealing
• Suitable for: indoor and outdoor use
• Application method: cartridge for use with a caulking gun
• Properties: weather-resistant, load-bearing after curing, elastic

How to use

Ensure surfaces are clean, dry and free of dust, grease or loose particles. Cut the cartridge tip to the required bead size and use a standard caulking gun to apply the sealant evenly into the joint or gap. Tool the joint within the working time to obtain a smooth finish and ensure contact with both sides of the joint. Allow the sealant to cure according to ambient temperature and humidity; curing time depends on joint depth and environmental conditions. Remove uncured product with an appropriate solvent; cured material must be removed mechanically.

What to consider before purchase

• Confirm substrate compatibility, especially with plastics, bitumen and coated surfaces
• Assess joint dimensions to determine required volume and joint backing if necessary
• Verify whether subsequent painting is needed and test paint adhesion after curing
• Consider temperature and humidity at the time of application and during curing

Usage recommendations

For best results, store cartridges in a cool, dry place before use, apply within the recommended temperature range, and use appropriate joint backing or tape to control sealant depth. Test adhesion on unfamiliar substrates and allow full curing before subjecting joints to heavy loads or continuous moisture.
