MF890 silicone sealant
MF890 silicone sealing gum is a high modulus, a single component elastic sealant, designed for waterproof seams that require a clean glass and metal doors and windows. It is cured after contacting the water in the atmosphere, forming the elastic sealant, has durable, weather resistant sealing performance, can form good bonding with most building materials, can provide excellent weathering on various building doors and windows Sealing performance.
Product Description
Color
In addition to black, gray, white, can also be negotiated according to special colors required by customers
Standard Adopt Standard
MF890 silicone sealant meets or even surpasses the following standard specification: GB / T 14683G, F
Application method 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.
On the surface of the backing material and the seam, the sealing surface is formed.
After the whole flat, the shield tape is torn off immediately. Do not help with liquids such as water, soapy water, alcohol.
Operational 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
Storage and validity Storage and Expiration Date
Packing the goods, in a cool, ventilated, dry, can be stored in 12 months, using the "validity" of the product packaging
Packaging package
Plastic tube: 300ml per piece, 25 soft packages per box: 592ml each, 20

Use restrictions use restriction
This product is not allowed to be used as a structural glue, nor is it tested or stated as suitable for medical or medicinal.
This product is not suitable for:
The seam in the groundwater or excessive friction is immersed in the water.
It is possible to seep over oil, plasticizer, solvent, or some vulcanized rubber gasket or tape frost or humid surface
Fully contact with the air in the air during solidification (sealed adhesive needs moisture)
Application of sealing glue surface paint (general paint cannot attach in silica gel surface) Direct contact with food or other food grade surface applications
Glue
The shadow tape is applied according to the area where the seam is connected to ensure the neat and beautiful sealing sealing line.
For non-porous materials, there is usually no good adhesion, but for certain porous materials surface, it may be necessary to apply paint to ensure good bonding, it is recommended to be sticky before the project starts. Test test.
The MF890 silicone sealing glue continuously squeezes and fills the seam (the sealing glue can be used for construction using the 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 sealing glue has not been fed, the sealed adhesive is pressed flat with an appropriate force.

♦ 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.
