  Precautions and precautions
  The initial 20g of mixed glue may be insufficiently mixed and is not recommended.
  The glue mixed at room temperature should be used during the application period.
  Avoid contact with skin and eyes. If inadvertently, rinse immediately with plenty of water and consult a doctor if necessary;
  avoid contact with children; do not contaminate food, medicine or cosmetics.
  The heavy workpiece to be bonded should be avoided to move before it is completely cured, and measures should be taken to fix it when it is necessary to move.
  Recommended use conditions: temperature 15 ~ 35C, relative humidity 40% ~ 80%; if the temperature and humidity are lower than the recommended lower limit, the horn glue will cure more slowly, and if it is higher than the recommended upper limit, the construction time will be shortened.

   

  

  

  

Features and advantages
Excellent fire and flame retardant performance
High elasticity, high modulus
Neutral curing, no corrosion to the adhered surface
Excellent weathering resistance and good temperature resistance
It has good adhesion to most building materials without primer
No pollution to the environment

composition
One-component, neutral, room temperature moisture curing silicone sealant.

application
Structural applications, including assembly with glass and metal materials assembled in factories or construction sites. After being fully cured, the sealant layer forms a durable and elastic waterproof interface.
Used for structural assembly of building curtain walls, bonding and sealing of various fireproof doors and windows, flame-retardant sealing of all layers of curtain wall engineering, and flame-retardant sealing of waterproof, moisture-proof and decorative in public places.

product manual
DJ-A3-MF899F is used for structural assembly of building curtain walls, bonding and sealing of various fire doors and windows, flame-retardant sealing of all layers of curtain wall engineering, and flame-retardant sealing of waterproof, moisture-proof, decoration in public places. MF899F has the dual functions of fire retardant and structural bonding assembly. It has excellent weathering resistance and good bonding properties.
DJ-A3-MF899F is actually not affected by sunlight, rain, wind and snow, and extreme high and low temperatures. Its unique weather resistance allows it to remain essentially unchanged even if it is exposed to severe weather conditions if fully cured. The original design performance of the joint will not change significantly due to aging or exposure to the atmosphere, and the sealant still has water and weather resistance properties. The cured sealant remains elastic in the low temperature range of -60C to high temperature range of 180°C, and will not be embrittled, cracked or torn.
DJ-A3-MF899F is compatible with most substrates.

Adopt standard
GB 16776
GB/T 2408
JG/T475 and ETAG002 aging performance
GB 23864.
The width of structural adhesive should not be less than 6 mm.
The depth of structural adhesive shall not be less than 6 mm.
The width of the structural adhesive must be equal to or greater than the depth of the structural adhesive.
The formula for calculating the minimum width of structural adhesive (see Figure 1).
The joints of the structural glue must be able to fill the glue with the general standard construction method.
The joints of the structural adhesive must not move during curing.
The joint design must allow the structural adhesive to contact with air to facilitate curing.
When silicone structural sealant is used to support permanent load, its permanent load design strength is 1000kg/m2
Note: Other special systems may have different design guidelines. This kind of system
The most suitable criterion depends on the specific design. The above suggestions are the same as general industrial operations.

Application method
Surface cleaning
Remove all the grease, dust, water stains, frost, surface dirt, old sealant, assembly accessories and protective coatings and other impurities and contaminants left in the joints and assembly parts.
Metal, glass and plastic must be cleaned with solvents such as absolute ethanol, acetone, methyl ethyl ketone, isopropanol, etc. according to the "double-cloth wiping method". In all cases, the solvent must be wiped with a clean, lint-free white cloth. Do not use detergent or soapy water.

Use primer
The use of DJ-A3-MF899F generally does not require primer. If the adhesion test indicates that primer is needed, apply the primer thinly on the joint surface with a clean, lint-free cloth and let it dry before injecting glue. Corresponding tests must be done before glue injection to determine if primer is needed.
Padding material
Open-cell polyurethane foam, closed-cell polyethylene foam or non-venting polyolefin materials are recommended cushioning materials. As for shallow seams that cannot accommodate foam rods, polyethylene tape can be used instead.
Masking and correction
The area near the seam needs to be shielded to ensure a perfect appearance of the sealed area. Never let the masking tape touch the surface of the substrate to be injected. After finishing the work, the masking tape should be removed immediately.
Glue injection
As shown in Figure 1, install the cushion material, spacer spacer and masking tape. Continuously squeeze DJ-A3-MF899F into and fill the joints. Flatten the sealant on the gasket material and the surface of the joint with an appropriate force. The finishing process must be done at one go after the injection is completed and the surface is not skinned.It is recommended to use convex tools to trim the rubber surface into a concave shape, and soapy water should not be used as an auxiliary material for trimming. After the trimming is completed, immediately tear off the masking tape. On the glass assembly, the sealant injected on the bottom seam must be trimmed to a bevel to prevent water accumulation. Uncured sealant is never allowed to come in contact with non-grindable surfaces, such as polished marble, metal or glass surfaces, because excess sealant cannot be completely removed with organic or chlorinated solvents. Therefore, these surfaces must be covered, or extra care must be taken when injecting glue to prevent the sealant from contacting these surfaces. Once the uncured sealant touches these surfaces, it will leave a film on the surface, which will affect the unique aesthetics of the substrate.

Operation precautions
If it gets into the eyes accidentally, rinse immediately with plenty of water
D should not be in contact with the skin for a long time, avoid contact with children

Technical Services
Adhesion test
Our company will pass the standard laboratory test to evaluate the bonding performance of this product and the materials selected for the project (such as glass, metal and masonry, etc.), and submit the test results, product recommendations and surface cleaning methods in written form client.
Compatibility test
The incompatibility of materials will cause the silicone glue to discolor and even lose its adhesion. In order to avoid this kind of problem and ensure the compatibility of the material with the silicone glue, our company will also use the auxiliary materials provided by the customer for assembly (Such as cushion rods, layering strips and double-sided tapes, etc.) and our silicone rubber products are tested for compatibility.
The materials used in the project or the samples of I must be provided to our company for
Adhesion and compatibility test.

Structural assembly seam design
