composition
One-component, neutral, room temperature moisture curing silicone sealant.
application
DJ-A3-MF889F is suitable for bonding and sealing of all kinds of fireproof doors and windows, flame-retardant sealing of all layers of curtain wall engineering, and flame-retardant sealing of public places such as waterproof, moisture-proof and decoration.
product manual
DJ-A3-MF889F is a one-component, non-sagging, room temperature curing sealant, which has the dual functions of fire-retardant and weather-resistant bonding and sealing. It can be easily squeezed out under most of the ambient temperature, and can be cured by reacting with the moisture in the air to form a weather-resistant, fire-retardant silicone sealant.
colour
In addition to black, gray and white, it can also be produced in consultation according to the special colors required by customers
Adopt standard
DJ-A3-MF889F meets or exceeds the following standards and specifications:
GB/T 24267 SR 20HM

Application method
Surface cleaning
Remove all the grease, dust, water stains, frost, surface dirt, residual sealant, glass assembly accessories, protective coatings and other impurities and contaminants left in the joints and assembly parts.
Glue injection
Install backing materials, spacers, spacers and tapes as required. Masking tape should be used in the area connected to the seam to ensure a neat and beautiful sealant line.
For the surface of non-porous materials, there is usually no need to coat the primer to have good adhesion, but for some porous material surfaces, it may be necessary to coat the surface to ensure good adhesion. It is recommended to do the adhesion before the project starts. Result test.
Continuously squeeze DJ-A3-MF889F into and fill up the joints (sealant can be applied with pneumatic glue gun and other glue injection equipment). When using a pneumatic gun, the operating pressure should be adjusted to prevent bubbles from being generated during glue injection.
When the surface of the sealant is not yet skinned, flatten the sealant with appropriate strength
On the backing material and the surface of the joint, and smooth the surface of the sealant.
After leveling, remove the masking tape immediately. Do not use liquids such as water, soapy water, or alcohol to help level it.
