Formula Upgrade Improves Low-Shrinkage and Anti-Aging Performance for Specialized GRC Condensation Silicone

This optimized silicone is specially adapted to the heavy-load pouring environment of GRC and GFRC materials. It can withstand the pressure of concrete slurry and frequent demolding operations, effectively extending mold service life. In addition, the new formula improves anti-aging and weather resistance, adapting to high-temperature and high-humidity workshop environments in tropical and subtropical regions. Field tests show that the upgraded GRC mold silicone can increase the repeated casting times of European-style decorative components by more than 30%, greatly reducing mold replacement frequency for GRC manufacturers.
