FOAM SEALANT

Key Product Features

Excellent Gap-Filling Performance

The expanding foam conforms to irregular spaces and fills cavities that may be difficult to reach with conventional sealants. This helps create a more complete fill when the correct application method and expansion rate are used.

Strong Adhesion to Compatible Materials

The product is designed to adhere to a range of common construction substrates, such as concrete, masonry, wood, and selected metals and plastics. Actual adhesion depends on the surface condition, substrate type, and product formulation.

Thermal and Acoustic Insulation

The cured cellular structure can provide supplementary thermal and sound insulation by reducing air movement through installation gaps. Insulation performance depends on the foam density, thickness, installation quality, and surrounding structure.

Convenient Application

Depending on the packaging, the product can be dispensed using an attached straw or a compatible professional foam gun. This allows controlled application in gaps, corners, cavities, and other hard-to-reach areas.

Multiple Construction Applications

PU Foam Adhesive can support a variety of installation and renovation tasks, including filling openings, sealing frame-to-wall gaps, and bonding compatible insulation materials when the relevant product grade is designed for that purpose.

Typical Applications

Door and Window Installation

Used to fill suitable gaps between door or window frames and surrounding walls, helping reduce air leakage and providing supplementary insulation.

Pipe and Cable Penetrations

Can be used to fill suitable gaps around pipes and cable openings, provided the installation complies with relevant building and fire-safety requirements.

Insulation Board Installation

Purpose-formulated PU foam adhesives can be used to bond compatible insulation boards and construction panels to approved substrates.

Building Renovation

Useful for filling and repairing selected voids around frames, corners, wall openings, and other non-structural construction areas.

General Installation and Maintenance

Suitable for professional installers, contractors, maintenance teams, and construction-material distributors requiring practical gap-filling solutions.

Application and Installation Guide

Step 1: Prepare the Surface

Remove dust, loose particles, grease, and other contaminants from the application area. Ensure that the surface condition meets the product instructions. Protect adjacent finished surfaces before application.

Step 2: Prepare the Product

Check the product label and instructions before use. If the product is supplied in an aerosol can, shake it as directed. Attach the appropriate applicator or foam gun according to the packaging design.

Step 3: Apply the Foam

Dispense the foam gradually into the target gap. Avoid filling the entire cavity with uncured foam, because the material may expand after application. Follow the recommended filling ratio and application technique for the specific product.

Step 4: Allow the Foam to Cure

Leave the foam undisturbed for the recommended curing period. Tack-free time, cutting time, and full curing time are different measurements and should not be treated as interchangeable.

Step 5: Trim and Finish

After the foam has cured sufficiently, trim excess material with a suitable cutting tool. Where required, cover the exposed foam with a compatible finishing material to protect it from ultraviolet radiation and environmental exposure.

Important Installation Precautions

• Wear appropriate gloves and eye protection during application.

• Work in a well-ventilated area and avoid inhaling vapors or spray.

• Keep uncured foam away from skin, eyes, and unsuitable surfaces.

• Do not overfill cavities; expansion varies according to the product and environmental conditions.

• Do not expose uncured foam to ignition sources. Aerosol products may be highly flammable.

• Do not cut or load the material before it has reached the required stage of curing.

• Test compatibility with unfamiliar substrates before large-scale application.

• Follow the label, TDS, and Safety Data Sheet (SDS) for storage, handling, cleaning, and disposal.
