HONG YE SILICONE Silicone for Marble Resin Arts Molding is a professional-grade RTV 2 Silicone Rubber, specifically designed to meet the demands of marble resin art crafting, GRC casting, and food-grade mold production. As a two-component liquid silicone, it delivers outstanding transparency, minimal shrinkage, and strong tear resistance, and has obtained FDA approval to ensure safe contact with food. Its adjustable hardness and excellent chemical resistance make it suitable for rapid prototyping and durable art mold fabrication, providing precise detail replication and stable performance for artists and manufacturing clients worldwide.
Product Overview
This industrial Mold Making Silicone is made up of two components: part A is a free-flowing liquid, and part B is a curing agent. It offers two curing system choices—platinum cure (Q-series) and condensation cure—to meet different production needs. Specifically tailored for marble resin arts molding, it excels in capturing intricate textures, fine details, and architectural features of various artworks and castings. Its key advantages include high dimensional stability and non-deformability, which ensure consistent and accurate results for resin art, concrete, and PU castings. The food-safe and odorless formula enables its use in both artistic and food-related applications, making it a versatile Industrial mold silicone rubber for diverse B2B customers.

Product Features & Advantages
Our Q-series platinum cure silicone cures quickly and cleanly with high transparency, making it ideal for high-clarity marble resin molds and precision prototyping. Its minimal shrinkage and excellent dimensional stability allow for accurate reproduction of delicate details in marble art, GRC, and concrete, avoiding warping and size inconsistencies. Strong tear strength resists wear and shear, enabling hundreds of repeated molding cycles to reduce material costs and improve production efficiency. It has excellent chemical resistance, capable of withstanding erosion from aggressive resin components, PU, and concrete, serving as a versatile Mold Silicone for various casting materials. Fully FDA approved, it is odorless and non-toxic, suitable for food-grade mold making. It operates stably between -60°C and 200°C, adapting to high-temperature casting and long-term aging conditions.
Core Operation Steps
Step 1: Prepare the model. Thoroughly clean the master model and molding tools to prevent cure inhibition, which is crucial when using platinum cure silicone. Avoid contact with tin cure silicone, sulfur, sulfides, amine compounds, and pewter flux.
Step 2: Weigh and mix. Accurately measure part A and part B at a ratio of 1:1 or 10:1, stirring slowly and evenly to avoid air bubbles.
Step 3: Defoam. Vacuum the mixture for 2-3 minutes to remove trapped air. If no vacuum equipment is available, pour the mixture slowly along the edge of the mold frame.
Step 4: Prepare the mold. Enclose the model with plastic or wooden plates, and apply a release agent (such as detergent or soapy water) to facilitate demolding.
Step 5: Pour and cure. Pour the defoamed silicone into the mold frame, and allow it to cure completely at room temperature to get an FDA-approved mold.
Application Scenarios
Core applications include marble resin arts molding, GRC and concrete casting, PU resin art creation, and high-precision rapid prototyping (including urethane casting and vacuum casting). Food-grade applications: safe for making food molds, such as chocolate, candy, and other food crafts. Industrial applications: prototyping for toys, shoe molds, and architectural decorations, as well as the production of durable art molds for resin artists. This product achieves precise detail replication, reduces waste through its long mold service life, and meets food safety standards, making it a cost-effective solution for B2B buyers in the art, manufacturing, and food sectors.
Certifications and Compliance
Our silicone for marble resin arts molding holds FDA certification for food-grade safety, complies with ISO 9001 quality management system standards, and meets international environmental regulations. As a Platinum cured mold silicone, it adheres to strict industrial safety and performance benchmarks, ensuring reliability and compliance for global purchasers.
Customization Options
Curing system: Customers can select either platinum cure (Q-series, high transparency) or condensation cure silicone based on their production requirements. Hardness adjustment: Hardness can be modified by adding a moderate amount of silicone oil to create soft or rigid molds (excessive addition is not recommended). Packaging: Flexible options range from 1kg trial drums to 200kg bulk drums, suitable for both small artisans and large manufacturers. Additives: Fluidity, curing speed, or release performance can be adjusted to match the specific needs of resin art or prototyping processes.
FAQ
Q1: Is this silicone safe for contact with food?
A1: Yes, our product is FDA approved, non-toxic, and odorless, making it ideal for food-grade mold production.
Q2: Why is thorough model cleaning necessary?
A2: Platinum cure silicone (Q-series) is prone to cure inhibition. Contact with tin silicone, sulfur, amines, or pewter flux will prevent proper curing, so a clean model surface is essential.
Q3: Can the silicone’s hardness be adjusted?
A3: Yes, hardness can be adjusted by adding silicone oil. However, excessive addition will reduce the silicone’s strength and durability.
Q4: What is the product’s shelf life?
A4: When stored unopened in a cool, dry place below 32°C, the shelf life is 12 months.
Q5: Is this silicone suitable for rapid prototyping?
A5: Yes, its high transparency, precise replication capability, and fast curing speed make it well-suited for rapid prototyping, urethane casting, and silicone tooling applications.
