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

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

Packaging package
Plastic tube: 300ml per piece, 25 soft packages per box: 592ml each, 20
500ml of each box, 300ml per box, 35 per box
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.
