Use PU-50FC Polyurethane Sealant for: Structural bonding, anti-pick applications, pavement joints, and vehicular/marine manufacturing, providing a tough and durable seal.
Adheseal PU-50FC is a versatile polyurethane sealant designed for high-performance applications. Its single-component, moisture-curing formula ensures ease of use and rapid curing. This sealant offers excellent adhesion to a wide range of substrates, including concrete, metal, wood, and plastics, making it ideal for construction, industrial, and marine applications. Its high Shore A hardness provides anti-pick properties, suitable for public buildings and high-traffic areas. PU-50FC's permanent elasticity and high bond strength make it perfect for dynamic joints subject to movement and vibration.

Frequently Asked Questions About PU-50FC Polyurethane Sealant
Q: Can PU-50FC be used in underwater applications?
A: Yes, once cured, PU-50FC is suitable for below waterline applications. However, avoid internal swimming pool applications and exposure to high chlorine levels.
Q: Is priming required before applying PU-50FC?
A: Priming is often not required due to its high bond strength. However, for porous substrates or critical applications, use Everflex Supaprime. For non-porous substrates, use Adheseal 50A.
Q: What is the cure time for PU-50FC?
A: PU-50FC cures at a rate of 4mm per 24 hours at 25°C and 50% humidity. Cure times may vary depending on atmospheric conditions and substrate porosity.
Q: Can PU-50FC be painted?
A: Yes, PU-50FC is paintable with acrylic, oil, and rubber-based paints. Confirm adhesion and note that non-flexible paints may crack.
Q: How do I clean up PU-50FC?
A: While wet, clean tools and spills with Xylene. Cured product can be removed mechanically. Use Adheseal Hand Wipes for skin cleaning.
Q: What is the movement capability of PU-50FC?
A: PU-50FC has a movement capability of 25%, making it suitable for joints subject to movement and vibration.
Q: Is PU-50FC suitable for anti-pick applications?
A: Yes, its high Shore A hardness makes it suitable for anti-pick applications in public buildings, schools, and prisons.

How to apply PU-50FC Polyurethane Sealant:
- Prepare the surface: Clean and dry the substrate, mask joint edges if needed.
- Prime if necessary: Apply Everflex Supaprime for porous surfaces or Adheseal 50A for non-porous surfaces.
- Apply the sealant: Cut the nozzle at a 45° angle for sealing, or a 90° angle for adhesive applications.
- Tool the sealant: Smooth with a moistened spatula before skin formation.
- Clean up: Remove excess sealant with Xylene while wet.
PU-50FC Polyurethane Sealant limitations:
- Not suitable for aquariums or internal swimming pool applications with high chlorine levels.
- Not recommended for adhering mirrors or structural glazing.
- May discolour copper and brass.
- Not suitable for bituminous, natural rubber, or EPDM rubber surfaces.
- White colour may yellow slightly when exposed to UV.
- Requires atmospheric humidity to cure, not suitable for totally confined spaces.
Safety precautions when using PU-50FC Polyurethane Sealant:
- Personal Protective Equipment: Wear gloves, safety glasses, and respirator.
- Ventilation: Ensure adequate ventilation during application.
- Handling: Avoid skin and eye contact. Wash hands after use.
- First Aid: For skin contact, wash with soap and water. For eye contact, flush with water. If ingested, seek medical advice.
