HONG YE SILICONE Ornamental Concrete Relief Molding Silicone is a premium two-component RTV 2 Silicone Rubber, available in Condensation Curing Silicone Mold Rubber (tin-catalyzed) and Addition Curing Silicone (platinum-catalyzed). As core Mold Making Silicone, it features 30-40 Shore A suitable hardness, room-temperature curing (25℃, 3-6 hours) or heating curing, and excellent tear/tensile strength. With good fluidity, easy demolding, and high duplication times without deformation, it’s ideal for concrete relief, GRC/GFRC products, and garden decorations. Shelf life 12 months (25℃ sealed), compliant with global standards, it helps B2B buyers reduce mold replacement costs and ensure precise relief replication.
Product Overview
This professional Industrial mold silicone rubber is tailored for ornamental concrete relief molding, composed of flowable liquid Part A (silicone) and Part B (curing agent). It offers two optimized formulations: condensation curing silicone mold rubber (mix ratio 100:2-5, 10:1 for EU/US standards) and Platinum cured mold silicone (mix ratio 1:1/10:1/9:1). Designed to solve core pain points like mold deformation, difficult demolding, and low durability in concrete relief production, this liquid silicone supports both pouring and brushing operations, fitting simple and delicate patterns alike, making it a reliable choice for global construction decoration and garden product manufacturers.

Product Features & Advantages
Our product outperforms ordinary silicone with:
1. High duplication times and no deformation, ensuring consistent relief pattern precision for mass production.
2. Excellent mechanical properties, especially tear/tensile strength, extending mold service life.
3. Good fluidity and operability, supporting both pouring (simple patterns) and brushing (delicate patterns) operations.
4. Excellent flexibility for easy demolding, reducing relief product damage.
5. Room-temperature curing (25℃, 3-6 hours) or optional heating curing, adapting to different production rhythms.
6. 30-40 Shore A suitable hardness, balancing flexibility and support for concrete molding.
7. Dual formulations to match different regional (EU/US) and budget needs.
How to Use
Step 1: Prepare the master model, weigh silicone (Part A) and curing agent (Part B) per recommended ratio, stir evenly (uneven stirring causes partial curing and short mold life).
Step 2: Vacuum pump for less than 10 minutes (avoid cross-linking reaction).
Step 3: Choose operation mode – pouring (simple patterns, light viscosity for smooth flow) or brushing (delicate patterns, high viscosity to avoid flowing).
Step 4: Demold after 3-5 hours (best after 24 hours); set the mold for another 24 hours before mass production for optimal performance.
Application Scenarios
Primarily used for ornamental concrete relief mold making. Extended applications: cement, concrete stone, GRC/GFRC products (flower pots, fountains, polyurethane wood imitations, fiberglass products), garden decorations, and other construction decoration industries. It helps buyers improve relief pattern replication accuracy, shorten production cycles, reduce mold failure rates, and lower long-term manufacturing costs.
Certifications and Compliance
The product holds ISO 9001 quality management system certification and CE certification, complying with international industrial silicone norms and construction material safety standards. All formulations meet non-dangerous goods transport requirements, ensuring smooth global B2B procurement and customs clearance.
Customization Options
We offer OEM customization services: adjustable hardness (30-40 Shore A), viscosity (for pouring/brushing), curing speed (via catalyst type), and mixing ratios (adapting to EU/US standards). We also optimize formulas for enhanced concrete resistance, catering to Rapid prototyping silicone needs and large-scale relief production.
Production Process
Manufactured with high-purity Silicone raw materials, the process includes precise formula blending, closed vacuum mixing, multi-index testing (tear strength, curing speed, hardness), and standardized filling. Each batch undergoes strict pre-shipment inspection, supported by a professional R&D team and mature production lines, ensuring stable quality for bulk orders.
FAQ
1. What affects curing speed? Temperature and humidity – higher temperature/humidity accelerates curing.
2. Can I add silicone oil? Not recommended; 5%-10% can be added for softer molds or delicate patterns to ease demolding.
3. Which operation mode is better for delicate reliefs? Brushing operation, which replicates patterns exactly.
4. How long should I set the mold after demolding? 24 hours before mass production for optimal durability.
5. What’s the shelf life? 12 months when stored 25℃ in sealed original packages.
