Sika Boom® AP – High-Expansion Polyurethane Insulating Foam

Efficient One-Component Polyurethane Foam

Sika Boom® AP is a ready-to-use, one-component expanding polyurethane foam that simplifies sealing tasks around doors, windows, pipes, ducts, and joints. Pre-pressurized for ease of application, it expands significantly after dispensing, making it ideal for quickly filling gaps and voids with minimal effort.

Outstanding Insulation and Acoustic Performance

Extending over twice its initial volume, this foam fills cavities completely. After curing, it transforms into a semi-rigid mass with a closed-cell structure—offering excellent thermal and acoustic insulation. This ensures enhanced comfort and energy conservation for internal spaces in Bangalore’s climate.

Rapid Curing for On-Site Efficiency

Optimized for productivity, Sika Boom® AP is tack-free in approximately 10 minutes and cures fully within 24 hours. This quick turnaround supports fast project progression and allows prompt sanding or finishing without prolonged wait times.

Durable, Stable, and Long-Lasting

Once cured, the foam remains stable and resilient, tolerating temperature extremes from –40 °C to +90 °C without degradation. It adheres well to substrates like bricks, concrete, wood, metal, and most plastic types, ensuring dependable long-term performance in diverse conditions.

Safe, User-Friendly Application

The product is designed for clean and safe handling—easy-to-use with low vapor emission, minimizing hazards during application. Its controlled expansion reduces overfill and waste, making it suitable for both DIY consumers and professional contractors alike.

Optimized Packaging & Storage

Available in various sizes (e.g., 500 ml, 750 ml, and 850 ml), Sika Boom® AP maximizes yield and value. When stored upright in cool, dry conditions, it maintains effectiveness for up to 12 months. The user-friendly canister design ensures efficient use and minimal product loss.
