HONG YE SILICONE RTV2 Silicone for Molds Replication is a premium two-component RTV 2 Silicone Rubber, available in Platinum cured mold silicone (mix ratio 1:1/10:1) and tin-based Condensation Curing Silicone Mold Rubber (mix ratio 100:3). As core Mold Making Silicone , it features exceptional fluidity, room-temperature curing (2-4 hours), low shrinkage, and high tensile/tear strength. Suitable for pouring and brushing molding, it’s FDA-certified Food grade mold silicone, ideal for concrete stones, resin, gypsum, food molds, and prototyping. It ensures high duplication times and easy demolding, reducing costs for global B2B buyers.
Product Overview
This professional liquid silicone is engineered for high-precision mold replication, belonging to our Industrial mold silicone rubber lineup. It consists of two flowable components (Part A: liquid silicone, Part B: curing agent) with two tailored formulations: platinum cured Mold Silicone (popular 1:1 ratio, eco-friendly) and tin-based condensation curing silicone mold rubber (100:3 ratio, cost-effective). With outstanding operability and fluidity, it cures at room temperature without extra equipment, ensuring tight detail replication and easy demolding. It solves core pain points like shrinkage and low durability, making it a reliable choice for manufacturers in decoration, craft, food, and rapid prototyping industries.

Product Features & Advantages
It boasts exceptional fluidity for effortless pouring/brushing, ensuring full coverage of complex details. Room-temperature curing (2-4 hours) boosts production efficiency without heating equipment. Ultra-low shrinkage (≤0.1%) guarantees dimensional stability and high replication accuracy. High tensile and tear strength extend mold service life, supporting multiple duplication cycles. Platinum variant is FDA-certified food grade, non-toxic odorless, suitable for food contact. Easy demolding reduces product damage and labor costs. Compared to single-formula silicone, it offers dual options (platinum/tin) for different budget and application needs.
How to Use
Step 1: Select platinum or tin-based silicone, prepare Part A and B in the specified mix ratio.
Step 2: Stir the two components evenly to avoid air bubbles and ensure uniform curing.
Step 3: Perform vacuum defoaming (optional) for bubble-free molds, especially for food or delicate crafts.
Step 4: Apply via pouring (simple shapes) or brushing (complex details) onto the master model.
Step 5: Allow curing at room temperature for 2-4 hours (avoid disturbance during curing).
Step 6: Demold gently after full curing; the mold is ready for repeated use.
Application Scenarios
Widely used for making elastic molds for concrete stones, wax, PU, resin, gypsum casting, candle molding, and FDA-compliant food molds (chocolate, candy). It also applies to Rapid prototyping silicone, Prototype silicone , Toy mold silicone , and craft mold production. It helps buyers improve mold precision, reduce replacement frequency, cut labor costs, and enhance product consistency for mass production.
Certifications and Compliance
The product holds ISO 9001 quality management system certification, CE safety certification, and FDA certification (platinum variant as food grade mold silicone). It complies with international industrial and food safety standards, ensuring smooth global procurement and customs clearance.
Customization Options
We offer OEM customization services, including adjustable hardness (10-30 Shore A), viscosity, curing speed, and color. We also support formula optimization for specific applications (e.g., high-temperature resistance) and mix ratio adjustments, catering to small-batch prototyping and large-scale production needs.
Production Process
Manufactured with high-purity Silicone raw materials, the product undergoes precise formula blending, closed vacuum mixing, multi-index performance testing (tensile strength, shrinkage), and standardized filling. Each batch is inspected before shipment, supported by mature production lines and strict quality control, ensuring stable performance for bulk orders.
