When using neutral glue, it is inevitable to encounter some problems. Below, and 995 neutral silicone glue sales company Xiaobian together to look at these two situations!

Neutral glue after dry glue, the surface has a powdery thing, what is the reason? In general, there are several cases:

1, the powder phenomenon of rubber strip is the selection of raw materials of rubber itself has defects;

2. Uneven mixing of raw materials;

3, may be due to the impact of the construction environment, more dust is easy to adsorption on the rubber surface and this situation.

Why neutral adhesive bonding some aluminum plastic board, plastic steel doors and Windows effect is not good or stick?

This phenomenon generally occurs in alcohol-type neutral adhesive, because the miscibility of the material on the aluminum plastic plate and the plastic steel door window is not good with alcohol-type silicone adhesive, which affects the bonding quality.

In this case, it is recommended that users choose ketone oxime type neutral glue, which will greatly reduce the occurrence of this situation; If the user chooses alcohol neutral rubber, should first use acetone or xylene wipe the surface of the substrate, to be completely dry after the substrate surface sizing; The scrubbed substrate should be constructed within one hour.

Therefore, we repeatedly emphasize that due to the diversity of substrate materials, users should test the compatibility between glue and substrate before use according to their own needs, so as to observe whether the compatibility meets the use needs.
