The 66533 Rectorseal Biostop BF 150 is a high-quality water-based intumescent firestopping sealant. This product is designed to provide superior fire protection for penetrations and openings in fire-rated walls, floors, and ceilings.
The Biostop BF 150 is a two-component system that consists of a resin and a hardener. Once mixed, it forms a flexible, non-shrinking sealant that expands up to 500% when exposed to heat, creating an effective fire barrier. This expansion capability helps to maintain the integrity of the fire-rated assembly, ensuring that it continues to perform its intended function in the event of a fire.
The product is available in a 10.3 fl oz (300 ml) cartridge, making it easy to use and apply. It is designed to be compatible with a wide range of materials, including steel, concrete, gypsum, and other common building materials. The Biostop BF 150 is also easy to apply, with a low viscosity that allows for smooth, even coating.
One of the key benefits of the Biostop BF 150 is its water-based formula. This makes it environmentally friendly, as it is free from harmful solvents and other volatile organic compounds (VOCs). It is also easy to clean up, as it can be removed with water.
The product is also resistant to mold and mildew, thanks to its biocidal properties. This means that it can help to prevent the growth of harmful bacteria and fungi, which can cause damage to building materials and pose health risks to occupants.
Overall, the 66533 Rectorseal Biostop BF 150 is a high-performance firestopping sealant that offers superior protection against fire, as well as resistance to mold and mildew. Its easy-to-use formula and environmentally friendly properties make it a popular choice for contractors and building professionals.
