💡 Why does closed cell structure matter for silicone bonding performance?
Closed cell structure acts as a barrier against moisture and debris accumulation.
- Prevents moisture absorption which keeps sealants durable against weather exposure
- Maintains elasticity allowing joints to move without breaking adhesive bonds
- Reduces sealant consumption by filling gaps efficiently before application starts
- Improves job quality with firm backing that supports optimal bead formation
