Product Description
Features and advantages
excellent fire flame retardancy
Neutral curing, no corrosion of the viscous surface, suitable for co-plating glass, float glass, wood material, aluminum profile, galvanized steel plate, brick and other materials
2% of the original seam width can be stretched / compressed 20%
excellent weather resistance and good temperature resistance, sunshine, rain, ice and snow, ozone or extreme temperatures will not cause adverse effects
Do not need to use a primer to achieve good bonding without using the primer
It is an ideal sealing material for stretching, connection, peripheral seal, and other mobile seams. It is used in general split guns to extrud out at any time.
excellent anti-drooping performance
No pollution to the environment
Composition
Single component, neutral, room temperature water gas curing silicone sealant.
Application
DJ-A3-MF889F is suitable for all kinds of fire doors and windows bonding seals, wall engineering, flame retardant seals, waterproof, moisture-proof, decoration, etc. of public places.
Product Description
DJ-A3-MF889F is a single component, no drooping, room temperature curing sealant, double function with fire flame retardant and weather resistant bonding seal. It can be easily extruded at most external ambient temperatures, and solidifying a hot flame retardant silicone sealing glue with a reaction to reacting with moisture in the air.
Colour
In addition to black, gray, white, can also be negotiated according to special colors required by customers
Standard
DJ-A3-MF889F meets or exceeds the following standard specification:
GB / T 24267 SR20HM
GB / T 14683 G, F 20hm
ASTMC 920 S, NS type, 20, for NT, G, Class A application
ISO 11600 F, G 20HM
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 spacer, hover spacer 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 bonding, it is recommended to do before the project starts. Adhesive test.
Continuously squeeze the DJ-A3-MF889f into and filled with 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 prevent bubbles when globling.
When the surface of the sealant is not yet fell, the sealed adhesive is flattened on the surface of the backing material and the surface of the sealing glue.
After the entire 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 immediately use a lot of water, you will not contact the skin for a long time, avoid children to contact non-pollutable food, drugs or cosmetics
