Description

Use Adheseal PU-15 for: Sealing movement and connection joints, window perimeters, expansion joints, and metal cladding.

Adheseal PU-15 is a high-performance, low modulus polyurethane sealant designed for a wide range of construction applications. Its superior elasticity allows it to accommodate movement up to ±25% of the original joint width, making it ideal for dynamic joints. This sealant is particularly favoured for window fixing and perimeter sealing, offering excellent adhesion to common building materials like concrete, metal, and wood. It cures to form a permanently elastic, dustproof, and waterproof seal, ensuring long-term durability and resistance to mould and mildew.

Key Features of Adheseal PU-15

High Flexibility: Accommodates joint movement up to ±25%, preventing cracks and maintaining a durable seal in dynamic structures like expansion joints and curtain walls.
Excellent Adhesion: Bonds strongly to a variety of substrates, including masonry, metal, timber, and plastics, reducing the need for extensive priming and ensuring a reliable seal.
Weather and Mould Resistant: Withstands harsh environmental conditions, including UV exposure and high humidity, making it suitable for both interior and exterior applications.
Paintable: Can be painted with acrylic, oil, and rubber-based paints, allowing for seamless integration with the surrounding finishes (preliminary adhesion tests recommended).
Low VOC: Meets "green star" environmental criteria, minimizing harmful emissions and contributing to healthier indoor air quality.
Submersible when cured: Once fully cured, the sealant is suitable for below waterline applications.

Technical Overview

Adheseal PU-15 is formulated to provide a durable and flexible seal, capable of withstanding significant movement and environmental stress. Its low modulus ensures that the sealant can elongate and compress without transferring excessive stress to the substrates. This is particularly beneficial in applications like precast panel joints and metal cladding, where thermal expansion and contraction are common.

Chemical Properties: Polyurethane-based, moisture-curing sealant that provides excellent resistance to water, detergent solutions, and moderate diluted acids and alkalis.

Application Temperature Range: +5°C to +40°C (41°F to 104°F). Ensure surfaces are dry and clean before application. Avoid applying in extreme temperatures to ensure proper curing and adhesion.

Application Information

Required Tools: Caulking gun, spatula, masking tape, Xylene (for cleaning), Adheseal 50A surface prep (for non-porous substrates), Everflex Supaprime (for porous substrates), backer rod.
Trade-Specific Tips: Use a 2:1 width-to-depth ratio for optimal joint performance. For deeper joints, use a backer rod to control sealant depth and prevent three-sided adhesion. Always perform adhesion tests on critical applications and use masking tape for neat finishes.
Common Issues and Solutions: Bubbling can occur from entrapped air; ensure proper tooling and avoid overworking the sealant. Poor adhesion can be prevented by thorough surface preparation and using the appropriate primer.

Storage and Shelf Life

Storage Requirements: Store in a cool, dry place between 10°C and 35°C (50°F and 95°F).
Shelf Life Information: 12 months from the date of production when stored in original, unopened packaging.
Temperature Considerations: Avoid storing in extreme temperatures or direct sunlight to maintain product integrity.

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.

How To Apply

How to apply Adheseal PU-15 Polyurethane Sealant:

Prepare the surfaces: Ensure surfaces are clean, dry, and free from contaminants.
Prime if necessary: Use appropriate primer for porous or non-porous substrates.
Install backing rod: Use an open-cell foam backing rod for joints deeper than 10mm.

Tool the sealant: Smooth the surface with a moistened spatula before skin formation.
Clean up: Remove excess sealant and masking tape while wet.

Limitations and Safety Info

Adheseal PU-15 limitations:

Not suitable for internal swimming pool applications or prolonged exposure to high chlorine levels (max 5ppm).
Not for use in totally confined spaces as it requires atmospheric moisture to cure.
Avoid use on aquariums, mirrors (use Hi-Power/MS609), and structural glazing (use N-80 or N-60 silicone).
Not recommended for composite panels (use Hi-Flex Construction), natural rubber, EPDM rubber, or materials that leach oils, plasticisers, or solvents.
May discolour copper and brass.
