Tetrabromoether has fire prevention effect and is suitable for fire prevention treatment of walls, floors and finishes. In order to give full play to the use requirements of tetrabromoether, strict requirements must be put forward for the environment when using it to make it known to the public. The details can be learned through the following introduction.

2. When using, first consider the use environment, and first clean the surface to ensure flatness and integrity.
3. If the temperature is too high to add, sagging, cracking, discoloration and other phenomena may occur. Try to avoid direct sunlight to prevent accidents.
4. In addition to the temperature problem, the tetrabromoether state may also be affected by low temperature in a low temperature environment, becoming thick and stiff, and difficult to paint.
