Product Features & Advantages
It offers two curing systems to fit different production needs: addition curing silicone for high clarity and fast curing, and condensation curing silicone for flexible application scenarios, ideal for Rapid prototyping silicone projects and large-scale 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 can accurately replicate intricate details of sculptures, architectural elements, and furniture molds, avoiding warping and size errors. High tear strength and enhanced durability allow hundreds of repeated molding cycles, reducing material waste and cutting long-term production costs. Excellent heat resistance and high elongation enable it to adapt to high-temperature casting environments and complex mold designs, suitable for tire molding, low melting alloys, and ceramic mold making. Food-safe variants are available, complying with FDA standards for candle mold making and food-related craft applications.
Core Operation Steps
Step 1: Prepare the master model and molding tools, cleaning them thoroughly to remove any contaminants that might cause cure inhibition, especially for addition curing silicone variants. Step 2: Accurately weigh Part A (silicone base) and Part B (curing agent) according to the recommended ratio, then stir slowly and evenly to avoid air bubbles and ensure full mixing. Step 3: Perform 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 minimize bubbles. Step 4: Enclose the master model in a mold frame and apply a release agent to make demolding easier. Step 5: Pour the de-aired silicone into the mold frame, cure it at room temperature or with heat for faster results, and the finished mold is ready for poly resin arts casting once fully cured.
Application Scenarios
Core applications include poly resin arts casting, resin crafts molding, sculpture and wax casting. It is also widely used 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 through long mold service life, and supports diverse industrial and artistic casting needs, making it a cost-effective choice for B2B buyers in resin art, manufacturing, and prototyping industries.
Certifications and Compliance
Our RTV Silicone for Poly Resin Arts Casting meets ISO 9001 quality management system standards and international industrial safety requirements. Food-safe variants comply with FDA regulations, ensuring they are suitable 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 ensure consistent and reliable performance in all casting scenarios.
Customization Options
Customers can choose between addition curing silicone (for high transparency and fast curing) and condensation curing silicone based on project requirements. Silicone hardness can be customized to meet the needs of soft or rigid molds. Packaging options are 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.
