·POSITION:ApplicationCommon Question → Why do bulges and blisters appear during the application of alkoxy sealant? How to reduce and avoid this phenomenon?

Why is the storage stability of alkoxy sealant relatively poor?

There are many reasons for the poor storage stability of alkoxy sealant, but there are two main reasons:

1. The methanol produced during the storage of sealant will cause alkoxy end-capping of OH Polymer, which will eventually cause OH Polymer to lose its reactivity.

2. Due to its high reactivity, titanium complexes are prone to reaction or hydrolysis and lose catalytic activity during storage.
