Technical Overview

Adheseal PU-15 is a low modulus, moisture-curing polyurethane sealant designed for movement and connection joints. Its formulation ensures high elasticity and durability, making it suitable for a wide range of applications. The sealant cures to form a permanently elastic and dustproof seal, accommodating movement up to 30%.

Chemical Properties: Polyurethane-based sealant with excellent resistance to water, detergents, and dilute chemicals. Its low modulus formulation ensures flexibility and durability.

Application Temperature Range: +5°C to +40°C (41°F to 104°F). This range allows for application in various Australian climates, ensuring the sealant remains workable in both warm and cool conditions.

Application Information

  • Required Tools: Caulking gun, smoothing spatula, masking tape, and cleaning solvents (Xylene).
  • Trade-Specific Tips: For builders, ensure proper joint design and use backing rod for optimal performance. Glaziers should ensure clean surfaces and use appropriate primers for non-porous substrates.
  • Common Issues and Solutions: Avoid application in totally confined spaces due to moisture curing requirements. Ensure proper surface preparation and priming for optimal adhesion.

Common Questions  

Frequently Asked Questions About Adheseal PU-15

Q: What is the best way to apply Adheseal PU-15 for a clean finish?

A: For a clean finish, use masking tape along the joint edges and remove it while the sealant is still wet. Apply the sealant with a caulking gun at a 45-degree angle, ensuring it fills the joint completely. Tool the sealant with a moistened spatula before it skins over.

Q: How does Adheseal PU-15 perform in extreme weather conditions?

A: Adheseal PU-15 is designed to withstand a range of weather conditions, including UV exposure and temperature variations. Its high elasticity and weather resistance ensure a durable seal, preventing cracks and maintaining integrity over time.

Q: Can Adheseal PU-15 be used on different types of building materials?

A: Yes, Adheseal PU-15 has excellent adhesion to various substrates, including concrete, metal, timber, and plastics. However, for optimal adhesion, especially on non-porous surfaces, use Adheseal 50A surface prep. For porous surfaces, use Everflex Supaprime.

Q: What are the technical properties that make Adheseal PU-15 suitable for movement joints?

A: Adheseal PU-15 has a low modulus and high elasticity, allowing it to accommodate joint movement up to ±25%. This flexibility prevents stress transfer to the substrates, ensuring long-term durability and preventing cracks in dynamic structures.

Q: What safety precautions should I take when using Adheseal PU-15?

A: Use in a well-ventilated area. Wear gloves, safety glasses, and, if necessary, a respirator. Clean any spills immediately with Xylene. If the product comes into contact with skin or eyes, wash thoroughly with water. Consult the SDS for detailed safety information.

Q: Can Adheseal PU-15 be used below the waterline?

A: Yes, once fully cured, Adheseal PU-15 is suitable for below waterline applications. This makes it versatile for marine environments and other applications where water immersion is a factor.

Q: How long does Adheseal PU-15 take to cure?

A: Adheseal PU-15 has a skin time of approximately 10 minutes and cures at a rate of 2mm per 24 hours at 25°C and 50% humidity. Cure times can vary based on temperature and humidity.

  • May discolour copper and brass.
  • Not for use on bituminous surfaces.
  • Avoid application when moisture-vapor-transmission is emanating from the substrate or if air-entrapment can occur, as this may cause bubbling.

Safety precautions when using Adheseal PU-15:

  • Personal Protective Equipment: Wear gloves, safety glasses, and a respirator if ventilation is inadequate.
  • Ventilation: Ensure adequate ventilation during application to avoid inhalation of vapors.
  • Handling: Wash hands thoroughly after handling and before eating or smoking. Clean spills immediately with Xylene.
