Product Introduction:

DJ-A3-BH-III fire sealant is a flame-retardant and expandable fire sealant that meets the relevant provisions of the national standard GB23864-2009. Its characteristic is good flame retardancy, and when exposed to fire, its volume expands by more than 5 times (unconstrained), effectively preventing flames and heat transfer. DJ-A3-BH-III fire sealant is a water-based fire sealant that is resistant to nuclear radiation; Resistant to LOCA; Resistant to cleaning agents and radioactive cleaning performance; Fire resistance stability; Does not contain toxic components such as halogens and sulfur; Water tightness and smoke tightness; Non corrosive, safe and environmentally friendly; Smoke is non-toxic; Efficient flame retardant; Convenient construction. DJ-A3-BH-III fire sealant is suitable for gaps in steel pipes and copper pipes with insulation layers that pass through vertical shafts, cabinets, cable walls, cable bundles, plastic pipelines (≤ 50mm), and HVAC ducts. [System Advantages] 1. Suitable for various types of fire sealing that can penetrate through 2. Easy construction 3. Subsequent supplementation of new cables can be carried out 4. Subsequent painting can be carried out 5. Easy to use for cleaning (before solidification) [Product Features] 1. Free from halogens, asbestos, and free silicon 2. Does not contain volatile organic solvents 3. Has good tightness, airtightness, and water tightness 4. Good sound insulation performance 5. Anti riot pressure of 100KPA 6. Good insulation, body resistance coefficient: 194 * 10 Ω. cm

Construction method:

Opening: Clean the opening. The surface to be coated with sealant should be cleaned of scattered debris, dust, oil stains, frost, and wax, and kept dry. Construction of fire prevention system: 1. According to the testing report requirements of relevant standards, fill the backing material (such as mineral wool) to the minimum thickness requirement and leave enough thickness for applying sealant to achieve a considerable fire resistance time. 2. Application of fireproof sealant: In order to achieve the desired fireproof effect, please apply the specified thickness to ensure that the sealant is in contact with the surface of the pipe substrate, in order to obtain maximum adhesion 3. Smooth the fireproof sealant: For better results, please immediately smooth the surface. For excessive adhesive, tools can be used to remove it with water before it hardens. 4. Please keep the interface intact for 48 hours after construction to complete the curing process. 5. If necessary, install identification stickers in a prominent location next to the fireproof sealing area as identification marks for later maintenance. 【 Precautions for Certification 】 When using sealant for fire sealing, please select the corresponding test report according to the relevant testing standards, and choose different dosages based on different fire resistance times. 【 Usage suggestion 】 Collaborate with the following backing materials for fire sealing: 1. Non combustible material mineral wool (density>100kg/m3); 2. Or fireproof foam.

Packaging and Transportation:

1. DJ-A3-BH-III fire sealant is packaged in cardboard boxes/plastic drums and is a safe and plastic solid substance that is non flammable, non explosive, non-toxic, odorless, and non corrosive. It is suitable for storage in a cool, dry, and ventilated place. 2. During product transportation, avoid exposure to sunlight and rain, and avoid damage during handling.
