Polyurethane Sealant-Adhesive Tytan PU 40 FC 300 ml — black

Tytan PU 40 FC 300 ml is a black polyurethane sealant‑adhesive formulated for flexible, durable joints and bonds in building and renovation work. The product combines adhesive strength with elasticity, making it suitable for sealing gaps, connecting different construction materials and creating weather‑resistant seals both indoors and outdoors. Packaged in a 300 ml cartridge, it is intended for application with a standard caulking gun and cures to a resilient polyurethane elastomer that resists moisture and moderate mechanical stress.

Advantages

The polyurethane composition provides strong adhesion to a variety of substrates while maintaining elasticity after curing, reducing the risk of joint failure from movement. It offers good weather and moisture resistance, useful for exterior applications, and forms a durable, paintable surface once fully cured. Supplied in a 300 ml cartridge, the product is compatible with common dispensing tools for controlled application.

Suitable for

• Sealing expansion and connection joints in façades and cladding
• Bonding construction materials such as concrete, wood, metal and some plastics
• Interior sealing where flexible, durable joints are required
• Exterior sealing and repairs exposed to weather and moisture

When it may not be suitable

This polyurethane sealant is not intended for continuous water immersion or as a primary structural adhesive for load‑bearing connections. It may not adhere well to certain low‑surface‑energy plastics (for example polyethylene or polypropylene) without appropriate surface treatment or primer. Surfaces contaminated with oil, dust or loose particles will reduce adhesion and should be properly prepared before application.

Key specifications

• Color: black
• Base chemistry: polyurethane
• Package volume: 300 ml cartridge
• Cure behaviour: forms an elastomeric seal after curing
• Application method: manual or pneumatic caulking gun
• Suitable for indoor and outdoor use

How to use

Ensure substrates are clean, dry and free of grease, dust and loose particles. Cut the cartridge nozzle to the desired bead size, fit into a compatible caulking gun, and apply continuous beads into joints or onto surfaces to be bonded. Tool the sealant shortly after application to achieve the required finish and contact with joint sides. Allow the sealant to cure undisturbed; curing time depends on bead thickness, temperature and humidity. Follow local ventilation and safety guidance during application.

What to consider before purchase

• Confirm color black matches the application area or finish requirements
• Verify compatibility with the specific substrates to be bonded or sealed
• Check whether a primer is needed for low‑energy surfaces
• Ensure a 300 ml cartridge volume is appropriate for the intended scope of work

Usage recommendations

For best results, prepare joints by removing old sealant and cleaning surfaces; apply at recommended temperatures and tool the bead within the open time. Store cartridges in a cool, dry place and use personal protective equipment to avoid skin contact during application.
