The treatment method of rubber carpet back release agent

Release agent is mixed with alkaline water and will turn white on the back of the carpet. At that time, white vinegar and ink were mixed and wiped clean, but it reappeared after two days. This was mainly due to the poor compatibility between alkali and rubber, and the alkaline substances kept leaking out. There is a professional term called spraying frost.

There are many types of release agents for the back of rubber carpets, including organic silicon surfactants, ionic surfactants, and non-ionic surfactants. I suggest you switch to a mold release agent that is more compatible with rubber and has no color even when sprayed with frost.
