HONG YE SILICONE Sculpture Molding Silicone Rubber is a professional two-component RTV 2 Silicone Rubber, available in Condensation Curing Silicone Mold Rubber and Addition Curing Silicone. As premium Mold Making Silicone and liquid silicone , it features 10–30 Shore A hardness, exceptional fluidity and good operability, curing at room temperature. With high tensile/tear strength, outstanding bubble releasing and multiple duplication cycles, it perfectly replicates fine textures of sculptures and crafts. Suitable for resin buddha, garden sculptures, fiberglass animal and cultural relic replication, it supports pouring molding and reduces mold replacement costs, improving production efficiency for global buyers.
Product Overview
This specialized Industrial mold silicone rubber is engineered for sculpture and craft molding, designed to capture intricate surface details and adapt to large-size artworks. It is a two-part room-temperature vulcanization product (Part A: flowable liquid silicone, Part B: curing agent/catalyst), covering two mature systems to meet different production needs. The 10–30 Shore A soft hardness balances flexibility and structural strength, ensuring easy demolding without damaging delicate sculptures. Its excellent fluidity enables full filling of complex mold cavities, making it a best-selling solution for resin crafts, toys, decorations and cultural relic replication manufacturers.

Product Features & Advantages
Exceptional fluidity ensures easy pouring and full coverage of fine patterns on sculpture surfaces. Dual curing systems (condensation/addition) provide flexible options for cost-sensitive or high-performance needs. High tensile and tear strength extend mold service life and support repeated duplication cycles. Room-temperature curing saves energy and simplifies production without special equipment. Good flexibility enables damage-free demolding, even for complex-shaped sculptures. Outstanding bubble releasing property ensures smooth mold surfaces and high-quality castings. 10–30 Shore A hardness is optimized for sculpture molding, balancing detail capture and structural stability.
How to Use the Product
Step 1: Prepare the sculpture prototype and molding frame, fix the prototype firmly. Apply a release agent if the prototype is glass or ceramic to prevent sticking.
Step 2: Select condensation or addition curing silicone, weigh Part A and Part B according to the recommended ratio, and stir evenly.
Step 3: Perform vacuum defoaming for 1–3 minutes to eliminate air bubbles, then pour the mixed silicone into the frame.
Step 4: Allow room-temperature curing until fully solidified (demoldable after 3–6 hours, full curing in 24 hours).
Step 5: Demold gently and use the mold for sculpture replication (resin, fiberglass, polyurethane, etc.).
Application Scenarios
Widely used for making molds for polyester arts and crafts, polyurethane statuary, resin buddha, clay figurine, garden sculptures, fiberglass animal models, mud toys, candles, soap, pottery, terracotta arts, cultural relic replication, rockery, artificial coral and more. Ideal for resin crafts manufacturers, toy factories, decoration suppliers, cultural relic restoration institutions and garden landscape enterprises. It helps buyers improve sculpture replication precision, reduce defective products, shorten production cycles and lower mold replacement costs, enhancing market competitiveness.
Certifications and Compliance
The product complies with ISO 9001 quality management system and CE industrial standards, ensuring stable quality and international market access. Addition curing silicone (platinum-based) meets eco-friendly requirements, and Food grade mold silicone options are available for soap/candle molding. All formulas conform to international chemical transportation and import regulations, supporting smooth cross-border B2B bulk procurement.
Customization Options
Support customization of hardness (10–30 Shore A), viscosity (adapt to different sculpture sizes and details), curing speed (match production efficiency) and mixing ratios. Provide formula optimization for extra-large garden sculptures or high-precision cultural relic replication. Customize packaging specifications (small sample jars to industrial drums) and vacuum packing solutions according to buyer storage and transportation needs.
Production Process
Adopt high-purity Silicone raw materials, go through precise proportioning, closed vacuum mixing (to ensure fluidity and bubble-free performance), multi-index performance testing (hardness, tear strength, curing speed), automatic filling and sealed packaging. Each production link is strictly quality-controlled, with mature production lines ensuring consistent batch quality. Sufficient inventory and efficient supply chain guarantee on-time delivery of large orders.
FAQ
Q1: What hardness is suitable for detailed sculpture molds?
A1: 10–25 Shore A is ideal for intricate patterns, while 25–30 Shore A suits simple-shaped or large sculptures.
Q2: Do I need a release agent for all prototypes?
A2: Only for smooth, non-porous materials (glass/ceramic); porous prototypes (clay, terracotta) do not require it.
Q3: How many times can one mold be reused?
A3: With high tear strength, it can be reused dozens to hundreds of times depending on use and maintenance.
Q4: Can it be used for large garden sculptures?
A4: Yes, we can customize viscosity and hardness to adapt to large-size mold making and ensure stable performance.
Q5: What’s the difference between condensation and addition curing types?
A5: Condensation type is cost-effective for industrial mass production; addition type (platinum-based) offers better fluidity and eco-friendliness for high-precision or food-contact (soap/candle) applications.
