.APPLICATION FIELD
- One component, solvent free, non-fogging, permanently plastic butyl sealant, formulated for primary sealing of insulating glass units.
- It can keep its plastic and sealing properties in a wide temperature range.
- Excellent adhesion properties on glass, aluminum alloy, galvanized steel and stainless steel.
- Minimum moisture vapour and gas permeation.
- Excellent temperature stability: - 30°C to 80°C.
♦ TECHNICAL DATA - TYPICAL PROPERTIES
MF322 two-component polyurethane corner glue
Mainly used for bonding and sealing between aluminum alloy corners and profile cavities in aluminum alloy door and window structures; suitable for bonding wooden doors, windows and doors; for processed different materials, such as wood, building materials, ceramics and metals It has good adhesion.
How to use instructions
Remove dirt, dust, oil, frost, etc. on the surface of the substrate; place the plastic nozzle on the open bottle mouth and tighten it, and use a dedicated 1:1 double bottle glue gun to inject glue. Uncured glue can be cleaned with special cleaning agents (or other solvents such as alcohol).
Packaging
Packaging
1:1 double plastic bottle packaging: 600 ml per group; 9 groups per carton
Transport transmission
This product is non-hazardous and can be transported by train, car, ship and plane
Store
Can be stored for 6 months in a cool, ventilated and dry place.
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
1. Low modulus, high-displacement capability with 100/50, is used with a structural sealing glue that satisfies ETAG 002, can provide 25-year quality assurance.
2. Neutral curing, no corrosion of the viscous surface, suitable for coating glass, float glass, wood material, aluminum profile, galvanized steel plate, brick and other materials.
3. Excellent high, low temperature performance and weather resistance, in its displacement capability, with high and low temperature interchangeance repeatedly definitive deformation, the performance of the sealant itself is extremely small.
4. Ideal sealing material for stretching, connection, peripheral seal, and other mobile seams.
5. Good bonding can be achieved for most building materials and components.
6. Easy to use, using a general split gun to extrude the application at any time.
7. Excellent anti-drooping performance.
8. No pollution to the environment.
Composition
Single component, neutral, room temperature water gas curing silicone sealant.
Application
MF889-25 Silicone weather resistant sealing adhesive is suitable for weather-resistant waterproof seals such as building curtain walls such as glass curtain walls in buildings.
Product Description
MF889-25 silicone weather resistant sealing glue is a single component, highly elastic, low modulus (LM) silicone weather resistant sealed adhesive, used in various forms of curtain wall buildings, especially high-rise building curtain walls and structural complex buildings form. 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. Due to its displacement capacity, it can provide 25-year quality assurance with the structural adhesive supporting of the construction industry standard JG / T 475 or European standard ETAG 002, which can be used in its displacement capability.
Colour
In addition to black, gray, white, can also be negotiated according to special colors required by customers
Standard
MF889-25 Silicone weather resistant sealing adhesive meets or even transcends the following standards:
.GB / T 22083 G, F 100/50
.JC / T 8821
.GB / T 14683 G, F
.Iso 11600 g, f
.ASTM C 920 S, NS type, 100/50, suitable for NT, G, Class A applications
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.
Glue
1. Install the backing material, isolate the block, hip bar, and tape, followed. The area connected to the seam should be shielded to ensure the clean and beautiful choice of the sealed Kiwai Gui.
2. For non-porous material surfaces, there is usually no need to coat the lacquer, but for some porous material surfaces, it may be necessary to apply paint to ensure good bonding, it is recommended to start construction. Do bonding.
3. Continuously squeeze the MF889-25 silicone weather resistant seal and filled the seam (sealing glue can be used for construction using pneumatic glue guns and other globes). When using a pneumatic gun, adjust the operating pressure to generate air bubbles when it is used.
4. When the surface of the sealing glue has not been fed, the sealed adhesive is pressed flat on the backing material and the surface of the sealing surface with appropriate strength, and the sealing surface is formed.
5. After the whole level is completed, the shield tape is torn off immediately. Do not help with liquids such as water, soapy water, alcohol.
Operation precautions
1. If you accidentally enter your eyes, you should rinse it immediately with a lot of water.
2. can not contact the skin for a long time, avoid children's contact
3. non-pollutable food, drug or cosmetics
4. Please use the adhesive test before use and refer to the technical information and safety data sheet of this company to learn about the safety use, hazards of the product. If the security matters not involved in this product, please follow the requirements of JGJ 102.
