Product Features & Advantages
Two curing systems are provided to meet diverse production needs: addition curing silicone for high transparency and quick curing, and condensation curing silicone for flexible application scenarios, ideal for Rapid prototyping silicone projects and large-volume resin art production. It has superior compatibility with common casting resins, urethane, and concrete, preventing mold corrosion and ensuring long service life for poly resin arts casting and industrial molding. With nil shrinkage and high dimensional stability, it precisely replicates intricate details of sculptures, architectural elements, and furniture molds, avoiding warping and size inconsistencies. High tear strength and enhanced durability support hundreds of repeated molding cycles, reducing material waste and lowering long-term production costs. Its good heat resistance and high elongation adapt to high-temperature casting environments and complex mold designs, suitable for tire molding, low melting alloys, and ceramic mold making. FDA-compliant food-safe variants are available for candle mold making and food-related craft uses.
Core Operation Steps
Step 1: Thoroughly clean the master model and molding tools to remove contaminants that could cause cure inhibition, particularly for addition curing silicone variants. Step 2: Accurately weigh Part A (silicone base) and Part B (curing agent) per the recommended ratio, then stir slowly and evenly to avoid air bubbles and ensure thorough mixing. Step 3: Conduct vacuum defoaming for 2-3 minutes to eliminate trapped air; if no vacuum equipment is available, pour the mixture slowly along the mold frame edge to reduce bubbles. Step 4: Enclose the master model in a mold frame and apply a release agent to facilitate easy demolding. Step 5: Pour the de-aired silicone into the mold frame, cure at room temperature or with heat for faster results, and the mold is ready for poly resin arts casting once fully cured.
Application Scenarios
Core applications include poly resin arts casting, resin crafts molding, and sculpture/wax casting. It is also widely applied in architectural restoration, concrete/GRC casting, gypsum and plaster decoration, furniture molding, tire molding, low melting alloys casting, ceramic mold making, candle mold making, and general plastic casting. This product delivers flawless detail replication, reduces production costs via long mold service life, and supports diverse industrial and artistic casting requirements, making it a cost-effective solution for B2B buyers in the resin art, manufacturing, and prototyping sectors.
Certifications and Compliance
Our RTV Silicone for Poly Resin Arts Casting complies with ISO 9001 quality management system standards and international industrial safety norms. Food-safe variants meet FDA regulations, ensuring suitability for global buyers in food-contact and artistic applications. As a high-quality industrial mold silicone rubber, it undergoes strict quality control during production to guarantee consistent, reliable performance in all casting situations.
Customization Options
Customers can select between addition curing silicone (for high transparency and fast curing) and condensation curing silicone based on project requirements. Silicone hardness can be customized to suit soft or rigid mold needs. Packaging is flexible: Part A is available in 1Kg to 200Kg containers, and Part B in 50g to 200Kg containers, suitable for small-batch prototyping or large-scale production. We can also adjust fluidity, curing speed, or release properties to match poly resin, urethane, or concrete casting workflows.
