Product Features & Advantages
High-elongation stretch formula, stretches smoothly to separate from deep undercut master patterns;
Full deep curing without thickness limit, uniform elasticity for thick complex undercut molds;
Smooth fluid liquid silicone fully fills narrow undercut gaps to restore complete tiny textures;
Extra high tear strength, no crack or fragment during stretch demolding cycles;
Better undercut demolding performance than rigid ordinary industrial Mold Silicone rubber;
Customizable stretch strength, softness and color for all complex undercut molding projects.
Step-by-Step Operation Guide
Mix stretch release silicone A and B evenly at 1:1 ratio for 2-3 minutes;
Vacuum defoam mixture for 2-5 mins to eliminate bubbles trapped in undercut cavities;
Pour liquid RTV mold silicone slowly into molds with deep undercut structures;
Choose proper curing mode based on production line arrangement;
Stretch silicone mold gently to release finished pieces without sharp pulling;
Seal unused silicone tightly and store indoors away from long-term heavy compression.
