What is the cause of yellowing of ceramic fiber board

Ceramic fiber board is suitable for high temperature fields where products require steel strength, but sometimes some yellowing may occur, which actually has a certain impact on our use. It not only affects aesthetics, but also has a certain influence on its use effect. So, what is the reason why it turns yellow? Below, we will mainly introduce its reasons.

1. The yellowing of ceramic fiberboard is mainly caused by the crosslinking agent and tackifier inside the neutral adhesive. The reason is that these two kinds of raw materials contain amino groups, which are easy to turn yellow. Many imported brand-name glass adhesives also appear yellowing.

2. If used with acidic glass glue, it may cause the neutral glue to turn yellow after curing.

3. It may be due to the prolonged storage time of the adhesive or the reaction between the adhesive and the substrate.

The yellowing of the ceramic fiber board may be due to the raw materials in the neutral binder, or due to improper use and storage. But, in the end, whatever it is, we need to keep it safe and deal with it in a timely manner.
