Why is the glass glue on the back of the mirror, after a period of time, there are mottling or glue marks on the mirror surface

Mirrors on the market usually have three different back coatings: Mercury, sterling silver and copper. Common mirrors have mottling after sizing for a period of time. In this case, most users use acid glass glue, and acid glass glue usually occurs with the above materials. The reaction caused the speckles on the mirror surface, so we emphasized that neutral glue should be used, and the neutral glue will be classified according to the purpose.

This phenomenon will not appear if the special glue for the champion mirror. The above are the improper selection of materials due to the diversity of substrates. Therefore, it is recommended that users use glue before Do a compatibility test to see if the glue is compatible with the material, and then use the appropriate glass glue product to avoid unnecessary losses.
