DJ-A3-MF889F-25 fire sealing rubber
DJ-A3-MF889F-25 is suitable for all kinds of fire doors and windows, the flame retardant seal, especially the gap between the glass curtain wall and its peripheral fire-separated member, and the slit between the edge of the entity wall Fire prevention, waterproof, moisture-proof, decoration, etc. of public places, etc.
Product Description
Features and advantages
Important flame retardant performance, fire prevention time long
High elasticity, low modulus, use silicone fire flame retardant structural sealing glue with ETAG 002 standard, can provide 25-year quality assurance
Excellent high, low temperature performance and climate aging resistance neutral curing, no corrosion of the viscous surface
For most building materials and components, there is no need to use the primer to achieve good bonding, ideal sealing materials for stretch, connection, peripheral seal and fire blockage.
Easy to use, using general split guns can be extruded at any time
No pollution to the environment
Excellent adhesion to a wide range of substrates including coated, enamelled and reflective glasses, anodised and polyester paint coated aluminium and stainless steel.
Excellent temperature stability: - 60°C t 1ao0c.
High level of mechanical properties.
High elasticity and high modulus.
Resistant to ozone.

Application
DJ-A3-MF889F-25 is suitable for all kinds of fire doors and windows bond seals, and the wall engineering is flame retardant, especially the gap between the glass curtain wall and its peripheral fire separator components, and the gap between the floor or the outer edge of the partition. Fire prevention, waterproof, moisture-proof, decoration, etc., etc., waterproof, moisture-proof, decoration and other flame retardant seals in the gap between the edge of the entity wall.
Product Description
DJ-A3-MF889F-25 is a single component, high-elastic, low-modulus (LM), is used in a variety of forms of buildings, especially high-rise build-up structural complex architectural forms of fire prevention seals. Blouse. It can be easily extruded at most external ambient temperatures, and solidifying silicone sealing gums in which persistent weathering is formed by means of moisture in the air. DJ-A3-MF889F-25 can reach 100 / 50LM and have good flame retardant and blocked; within its displacement capacity, it can meet the high and low temperature alternating transformation ability, which can meet the construction of construction industry standard JG / T475 or European standard ETAG 002 standard silicone fire flame retardant structure sealing glue supporting, providing 25 years of quality assurance.
Colour
In addition to black, gray, white, can also be negotiated according to special colors required by customers
Standard
DJ-A3-MF889F-25 meets or exceeds the following standard specification:
GB / T 22083 G, F 100/50
GB / T 24267 SR
GB / T 14683 G, FISO 11600 G, FGB 23864

Application method
Surface cleanup
Clear all impurities and contaminants such as grease, dust, water stains, frost, surface dirt, dust, water stains, frost, surface dirt, residual sealing gum, glass assembly accessories and protective coatings.
injection
Install the backing material, isolate the block, hover barrier and tape, etc. The area connected to the seam should be shielded to ensure the neat and beautiful sealing sealing line.
For non-porous materials, there is usually no good adhesion, but for some porous materials, it may be necessary to apply paint to ensure good adhesion, it is recommended to do before the project starts. Adhesive test.
Continuously squeeze the DJ-A3-MF889F-25 and filled the seam (the sealing glue can be used for construction using a pneumatic glue gun and other globes). When using a pneumatic gun, adjust the operating pressure to prevent bubbles when globling.
When the surface of the sealant is not yet fed, the sealed adhesive is pressed flat on the backing material and the surface of the sealing surface, and the sealing surface is metapy. After the whole flat, the shield tape is torn off immediately. Do not help with liquids such as water, soapy water, alcohol.
Operation precautions
If you accidentally enter your eyes, you should rinse it immediately with a lot of water.
Do not touch the skin for a long time, avoid children's contact
