Koelner RPS Polyurethane Foam with Applicator Tube 750ml

The Koelner RPS Polyurethane Foam is a professional-grade, one-component mounting and sealing solution designed for versatile construction applications. This 750ml aerosol canister comes equipped with a dedicated applicator tube, allowing for controlled and precise manual dispensing. The foam is engineered to expand and cure upon contact with atmospheric moisture, creating a stable, durable, and weather-resistant seal that effectively fills voids and gaps in various building structures.

Advantages

This polyurethane foam offers exceptional adhesion to a wide range of standard construction materials, including concrete, brick, wood, metal, and rigid PVC. Its high expansion rate ensures that gaps are filled completely, providing reliable thermal and acoustic insulation. The cured foam is resistant to moisture and aging, maintaining its structural integrity over time. Furthermore, the included applicator tube facilitates easy handling, making it an efficient choice for both small-scale repairs and larger installation projects without the need for specialized dispensing guns.

Suitable for

• Filling gaps and voids in walls and partitions
• Installing and sealing window and door frames
• Thermal insulation of pipe penetrations
• Sealing joints in roof structures
• Bonding and insulating construction elements

When it may not be suitable

This product is not intended for use on surfaces made of polyethylene, polypropylene, silicone, or Teflon, as it will not adhere to these materials. It is also not suitable for applications requiring structural load-bearing capabilities or for use in areas with constant water submersion.

Key specifications

• Volume: 750ml
• Type: One-component polyurethane foam
• Application method: Manual with applicator tube
• Curing mechanism: Moisture-curing
• Adhesion: Excellent on concrete, brick, wood, and metal

How to use

Before application, ensure that the surfaces are clean, free of dust, grease, and loose debris. For optimal results, slightly dampen the substrate with water to accelerate the curing process. Shake the canister vigorously for at least 30 seconds before attaching the applicator tube. Hold the canister upside down during application and fill the gap to approximately 50-60% of its volume, as the foam will expand significantly. Once cured, excess foam can be trimmed with a knife or sanded.

What to consider before purchase

• Check the compatibility of the foam with your specific building materials
• Ensure the ambient temperature is within the manufacturer's recommended range for application
• Consider the expansion rate to avoid overfilling gaps
• Use appropriate personal protective equipment, such as gloves and safety glasses

Usage recommendations

Store the canister in an upright position in a cool, dry place. Always use the product in well-ventilated areas and avoid exposure to direct sunlight or temperatures exceeding 50°C.
