DJ-A3-MF881F-25 fireproof sealant
Ready to work
Remove dirt on the surface of the substrate, such as: grease, dust, water, frost, old sealant, glass compound, protective coating, etc. Metal, glass and plastic surfaces should be cleaned by mechanical methods or solvents. The solvent should be wiped on the substrate with a clean, lint-free white cloth, and then wipe it with a clean, lint-free white cloth.
Primer
Use DJ-A3-MF881F-generally do not need to use primer. Compatibility before use
The test will determine whether to use the primer through the compatibility and adhesion test results.
Protection and construction
To ensure beauty and cleanliness, the area near the joints should be covered with protective tape during construction. The protective tape is not allowed to touch the glued surface, which is the area where the silicone sealant will adhere. The protective tape should be removed immediately after the gluing process is completed.
Equipment cleaning
After gluing is completed, the pipes of the gluing machine must be flushed with base glue or cleaned with solvent. If the cured sealant already exists inside the equipment, a suitable solvent should be used to clean it immediately to ensure that the surface of the pipe is clean after cleaning.
Repair
If the sealant is found to be damaged, use a clean knife to cut or scratch the surface of the cured sealant, and then re-gluing.
Precautions
Before construction, please read the product manual, safety data sheet, packaging label carefully to obtain information on safe use and health hazards.
Storage and validity period
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.
