Smooth-On - Rebound 25 Silcone

Rebound 25 Silcone

Create flexible molds that capture intricate undercuts without sagging

Vertical surfaces demand a mold-making material that stays exactly where you place it. Rebound 25's self-thickening formula maintains position on upright models without sagging or running, letting you build uniform layers across complex forms. This platinum-cure silicone brushes or spatulas onto surfaces with the consistency needed for controlled application, then cures with negligible shrinkage to capture every detail accurately.

The 1A:1B volume ratio eliminates scaling complications, measure equal amounts, mix thoroughly, and apply. Cured rubber delivers the flexibility essential for demolding pieces with deep undercuts; the material stretches around complex geometry without tearing, then returns to shape for repeated casting. This resilience makes it particularly effective for glove molds that need to invert and release cleanly.

Platinum-cure chemistry provides the stability and performance that production work requires. Whether you're molding sculpture with severe undercuts or creating reusable glove molds for small production runs, this silicone maintains dimensional accuracy across multiple castings while handling the mechanical demands of repeated demolding.
