How to Use (Step-by-Step)
1. Mix Part A and Part B of the durable silicone rubber in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes until uniform and bubble-free—this is critical for ensuring mold durability and precision.
2. Vacuum degas the mixed silicone for 2~5 minutes; adjust the time according to silicone viscosity, weight, and vacuum pressure to eliminate bubbles that affect mold quality.
3. Slowly pour the degassed silicone into the master mold, leveraging its excellent fluidity to fully cover all intricate details and cavities.
4. Cure at room temperature (4~5 hours) or heat at 80~120℃ for accelerated curing, fitting different mold making efficiency requirements.
5. Gently demold the cured silicone mold, clean it thoroughly before reuse; store unused silicone rubber in a sealed container indoors, away from sunlight and rain to preserve its durability.
Application Scenarios
This durable silicone rubber is widely used in various mold making scenarios, including industrial Mold Silicone rubber production, rapid prototyping silicone molds, high-precision handboards, metal craft molds, Food grade mold silicone production, and concrete/cultural stone molds. It brings tangible value: extending mold service life by 50%+, reducing replacement costs by 35%+, improving production efficiency, and helping mold manufacturers meet the diverse demands of global customers for long-lasting, high-quality molds.
