In modern buildings, fire safety is particularly important, especially at the locations where pipes pass through walls and line seals. The use of high-quality intumescent fireproof sealants can effectively prevent the spread of fire and protect personal safety. How to choose the right intumescent fireproof sealant will become an important issue of concern to builders.
1. How to Choose the Right Intumescent Fire Sealant?
1. High temperature resistance
Intumescent fire caulk can maintain a stable structure at high temperatures and will not produce toxic gases, greatly slowing down the spread of fire. It can resist fire and insulate for more than 4 hours
2. Expansion
Intumescent mastic sealants will expand at high temperatures, filling building gaps to block flames, so the expansion ratio is particularly important. The expansion ratio of Tengyu TA104 intumescent acrylic sealant is 5~6 times, which is suitable for sealing metal pipes and fireproof expansion joints, and can effectively prevent the spread of flames and heat.
3. Good adhesion and sealing
Fireproof sealants have excellent adhesion to most common building substrates, Thus forming a seamless whole to prevent the spread of smoke.
4. Anti-aging and stability
Even if exposed to outdoor environment for a long time, it can still ensure the stability of the structure without powdering or cracking.
5. Wide application
It is suitable for ductwork, joints in compartment walls and floors, fire-sealing expansion joints, sealing metal pipes, bundled cables, lightweight partitions, fire-rated doors, and service penetration seals where the integrity of fire walls or partitions needs to be maintained.
Choosing the right intumescent fire sealant is crucial to building safety. When choosing fireproof sealant, we must first understand the relevant performance parameters of the product and evaluate it according to actual needs.
