8. FAQ

Q: What’s the difference between Neutral silicone sealant and Acetic silicone sealant?

A. Neutral silicone sealant can be used both indoor or outdoor, but acetic silicone sealant just can be used indoor.

Q: What’s the impact of silicone sealant with bubble?

A. No bubble on the silicone sealant surface is a common performance for a good quality PU foam; if the silicone sealant has bubble, the silicone rubber is easy to break after curing.
