In recent years, due to environmental changes and increased safety awareness, fire safety has received widespread attention. Fireproof sealants have emerged as an important sealing material in the public eye. So what are fire rated sealants and what are their specific applications?
1. What are fire rated sealants?
Fireproof sealant is a fireproof sealing material with dual properties of sealing and fireproofing. It is available for filling cracks, gaps, or holes in building structures. It is also suitable for fireproofing applications such as fireproofing isolation of buildings, pipeline sealing, and cable penetration through walls. And it can effectively prevent the penetration of flames, smoke, and toxic gases.
2. Uses of fireproof sealants
- Sealing construction/expansion joints
- Top-of-wall joints
- Metal pipes
- Cable bundles
- HVAC penetrations
3. Common types of fireproof sealants
(1) Firestop acrylic sealant
Fire Rated Acrylic Sealant is a single-component, non-sag, fireproof water-based sealant.
What we show here is Tengyu TA103 Firestop Acrylic Sealant
It is an acrylic-based sealing compound, specifically for sealing low-movement interior joints in masonry and plasterboard, and it will provide a fire barrier for up to 4 hours.
Special Characteristics
- More than 4 hours of fire resistance without using backfilling materials in certain conditions.
- Good unprimed adhesion to most common construction substrates.
- No-slump.
- Paintable over using water-based paints.
- Easy to apply.
(2) Silicone fireproof sealant
Fireproof silicone sealant is a one-part, neutral cure, fire-rated product. It is suitable for the sealing of construction joints and around pipe penetrations.
What we show here is Tengyu TNS784 Fireproofing Silicone Sealant
It is fire rated for up to 4 hours and offers excellent adhesion to many common building substrates. It has outstanding resistance to UV and temperature extremes.
Special Characteristics
- Fire rating up to 4 hours.
- Excellent adhesion to many common building substrates.
- Long service life.
- Excellent weathering characteristics, including resistance to ozone, UV radiation, and temperature extremes.
(3) MS polymer fire rated caulk
What we show here is Tengyu TM513 Fire Barrier MS Sealant
It is non-hazardous, will not emit halogenated by-products under fire conditions, and contains no raw materials known to have an excellent effect on the environment. The sealant offers excellent levels of adhesion to most construction substrates and can be over-painted with oil, polyurethane, or latex paints.
Special Characteristics
- Fire rating up to 4 hours.
- Excellent adhesion to many common building substrates.
- Long service life.
- Excellent weathering characteristics, including resistance to ozone, UV radiation, and temperature extremes.
- Paintable
