Easy Operation & Customization: 1:1 mix ratio, dual curing options; shrinkage control, hardness, operating time can be tailored to diverse mold needs.
How to Use (Step-by-Step)
1. Mix Part A and Part B of the low shrinkage mold silicone in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes until uniform and bubble-free (critical for maintaining low shrinkage and dimensional stability).
2. Vacuum degas the mixture for 2~5 minutes (time varies by viscosity) to eliminate bubbles that affect mold quality and dimensional accuracy.
3. Slowly pour the degassed silicone into the master mold, leveraging its excellent fluidity to ensure full coverage of all intricate details.
4. Cure at room temperature (4~5 hours) or heat at 80~120℃ for accelerated curing, fitting batch production timelines.
5. Gently demold the cured silicone mold, clean before reuse; store unused silicone sealed indoors, away from sunlight and rain to preserve its low shrinkage performance.
Application Scenarios
This low shrinkage mold silicone is widely used in batch and high-stability mold making scenarios, including industrial mold silicone rubber production, resin casting molds, cultural stone and concrete molds, precision handboards, metal craft molds, and large-scale mold manufacturing.
