SHELF LIFE AND STORAGE
12 months from the date of production below 30°C.
The well-packaged product can be stored for 12 months in a cool, ventilated, and dry place, and used before the "expiry date" of the outer packaging of the product
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 the surface of some porous materials, primer may be required to ensure good adhesion. It is recommended to do it before the start of the project Adhesion test.
Continuously squeeze DJ-A3-MF899F-25 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 skinned, press the sealant on the backing material and the joint surface with appropriate strength, 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.
