7. FAQ

Q: What’s the reason that after used Neutral silicone sealant, there are some bubble on the surface?

A: When use the silicone sealant into the gap, the gap is damp, after the sunlight contact, it will make the steam effect the un-cured silicone sealant. That’s the reason why there are some bubble on the silicone surface.

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.
