Product Features & Advantages
This liquid silicone excels in high temperature and deformation resistance, keeping stable shape and size during concrete pouring and curing, no warping or distortion. It has strong tensile and tear strength, withstands wear and tear from repeated use, greatly prolonging mold service life and reducing replacement expenses. With outstanding fluidity, it flows smoothly into large mold cavities and covers every detail fully, ensuring high-precision molding. It also has excellent acid and alkali resistance, compatible with concrete and various resin materials, and good elongation makes demolding quick and effortless.
How to Use the Product
Step 1: Clean the concrete sound wall prototype thoroughly, wipe off dust, grease and impurities, and keep the surface dry to ensure molding quality.
Step 2: Pick the right hardness silicone (Shore 5A-40A) – opt for higher hardness for large concrete molds, lower hardness for detailed craft molds.
Step 3: Weigh the base silicone and matching curing agent strictly as per the ratio, stir slowly and evenly to avoid excess air bubbles.
Step 4: Pour or brush the mixed silicone onto the prototype, make sure all edges and details are fully covered, especially for large-area molds.
Step 5: Leave the silicone to cure fully at room temperature, then demold gently to get a durable, high-precision mold ready for concrete casting.
Application Scenarios
This liquid silicone is primarily used for fabricating large-scale concrete sound walls molds, core for road, railway and building sound insulation engineering.
