PRODUCT DETAILS
Product Introduction
DJ-A2-CD07 fireproof sealant is a flame-retardant and limb-swelling fireproof sealant. It is characterized by excellent flame retardancy and a volume expansion of more than five times (unrestricted) when exposed to fire, which can effectively prevent the transfer of flames and heat. DJ-A2-CD07 is a water-based fireproof sealant that is resistant to nuclear radiation. Resistant to LOCA Resistance to detergents and radioactive decontamination performance Long-lasting performance of over 40 years; Free of toxic components such as halogens and sulfur; Water-tight, smoke-airtight Non-corrosive, safe and environmentally friendly; The flue gas is non-toxic. High-efficiency flame retardancy The volume expands by more than five times when exposed to fire. Convenient for construction.
Application Scope
Vertical shafts, tray cabinets, cables passing through walls;
Gaps at the penetration points of steel pipes and copper pipes with insulation layers;
The gap at the penetration point of the cable bundle
The gap at the penetration point of plastic pipelines (≤50mm); The gap at the penetration point of the HVAC air duct.

Fire resistance and heat insulation | At 2.00 hours, the maximum single-point temperature rise on the backfire side of the specimen was 104.9°C, the maximum surface temperature rise at the backfire end of the penetration object 25mm away from the sealing material was 157.2°C, and the maximum temperature rise at any point on the frame surface of the backfire side was 74.1° C. The specimen did not lose its heat insulation property. |
Installation instructions
1. Clean the opening. The surface to be coated with DJ-A2-CD07 should be free of scattered debris, dust, oil stains, frost and wax, and kept dry.
2. Fill the backing material (such as mineral wool) in accordance with the test report requirements of relevant standards to the minimum thickness requirement, and leave sufficient thickness for coating DJ-A2-CD07 to achieve the corresponding fire resistance duration.
3. Application of fireproof sealant: To achieve the desired fireproof effect, apply the specified thickness and ensure that DJ-A2-CD07 all come into contact with the surface of the pipe base material to obtain the maximum adhesion.
4. Smooth out the fireproof sealant: For better results, please smooth out the surface immediately. For excessive mortar, it can be removed with a tool dipped in water before it hardens.
5. Please keep the interface undisturbed for 48 hours after the construction is completed to allow it to complete the curing process.
6. If necessary, install identification stickers in prominent positions beside the fireproof sealing areas to serve as identification marks for later maintenance.
7. The valid storage period of the product is 6 months.
