Japanese paper will not burn (it will not catch fire and will not spread).

Japanese paper flame retardant

Since soufa is an aqueous solution, it can only be painted with a brush and dried.

The evaporation rate after application is the same as water. There is no toxicity, so it is easy to handle.

Painted on newspaper, it looks like this. This also just burns and does not burn.
Unlike Japanese paper, the flame retardancy is inferior because it is thin.

Even tissue does not burn.
I cut Japanese paper into small pieces. I can achieve ul94 v0.

Achieving v0 with paper may be interesting.
