Fire-resistant acrylic sealant is a single-component gun-grade sealant formulated with fire-resistant acrylic emulsions. Designed to be partially flexible, it serves the specific purpose of fire sealing applications. This sealant is meticulously crafted with special additives and chemicals, ensuring fire resistance, ease of application, and effective joint sealing between construction parts under moderate stress. ASMACRYL-55 expands efficiently, providing a reliable seal against fire, smoke, and gas. Its properties above +120°C make it an ideal choice for achieving up to 4 hours of fire-resistant sealing in filled joints.
AREAS OF APPLICATION:
- Sealing around doors and window frames.
- Sealing should also be applied around ventilation grills.
- Joints between ceilings and wall joints in block work, where low movement is expected.
- Sealing duct holes and similar openings is also a common practice.
- Fire retardant applications.
- This product is ideal for areas with a potential fire risk due to its self-extinguishing nature.
ADVANTAGES:
- Excellent weatherability ensures durability under various environmental conditions.
- The tooling characteristics are excellent for professional use, facilitating precise application.
- Non-corrosive to metals, ensuring compatibility with metal substrates.
- It is suitable for alkaline substrates like concrete, mortar, and fibrous cement, offering versatility in its application.
- Matt finished, contributing to a visually appealing aesthetic.
- Excellent adhesion on most substrates without primer, enhancing convenience and efficiency.
- Solvent-free, resulting in low volume shrinkage during vulcanisation, ensuring a durable and reliable seal.
- Almost odourless, minimising discomfort during application.
- Non-sag, maintaining its shape and integrity when applied vertically or overhead, ensuring consistent performance.
