HONG YE SILICONE Ornamental Concrete Relief Molding Silicone is a premium two-component RTV 2 Silicone Rubber, available in Condensation Curing Silicone Mold Rubber (mix ratio 100:2~5, 10:1 for EU/US) and Addition Curing Silicone (1:1/10:1/9:1). As core Mold Making Silicone and liquid silicone , it features 30-40 Shore A adjustable hardness, high duplication times, excellent tensile/tear strength, and room-temperature curing (3-6 hours). Suitable for pouring/brushing, it ensures precise pattern replication and easy demolding for concrete/cement reliefs, garden decorations, etc. Certified and durable, it reduces mold replacement costs and boosts production efficiency for global B2B buyers.
Product Overview
This professional Industrial mold silicone rubber is tailored for ornamental concrete relief molding, composed of flowable liquid silicone (Part A) and curing agent (Part B). It offers two optimized formulations: tin-catalyzed condensation curing silicone mold rubber and platinum-catalyzed addition curing silicone (Platinum cured mold silicone), both curing at 25℃ (room temperature) or via heating. Engineered for concrete, cement, GRC/GFRC products, it solves core pain points like mold deformation, difficult demolding, and short service life in relief production. With balanced fluidity and mechanical strength, it’s ideal for both simple and intricate relief patterns, trusted by decoration and construction material manufacturers worldwide.

Product Features & Advantages
High duplication times and zero deformation ensure consistent relief pattern replication. Excellent tensile and tear strength withstands concrete/cement casting stress, extending mold life. Good fluidity and operability support both pouring (simple patterns) and brushing (intricate details) methods. Outstanding flexibility enables easy demolding without damaging relief edges. Room-temperature curing (3-6 hours) saves energy and equipment costs. 30-40 Shore A hardness balances rigidity and flexibility for concrete applications. Compared to general silicone, it’s optimized for concrete/cement corrosion resistance, reducing mold failure rates.
How to Use
Step 1: Prepare the master model, weigh liquid silicone (Part A) and curing agent (Part B) per recommended ratio, stir evenly to avoid partial curing.
Step 2: Conduct vacuum pumping for less than 10 minutes to remove bubbles (prevents cross-linking issues).
Step 3: Choose pouring (simple patterns, low viscosity) or brushing (intricate details, high viscosity) to apply the mixture.
Step 4: Cure at 25℃ for 3-5 hours (demold after 24h for best results).
Step 5: Set the mold for another 24h before mass production to ensure stability.
Application Scenarios
Widely used for concrete/cement relief mold making, GRC/GFRC products, flower pots, fountains, polyurethane wood imitations, fiberglass products, garden decorations, and architectural ornaments. It also fits reinforced plastic and construction decoration mold production. It helps buyers achieve precise pattern replication, reduce mold replacement frequency, shorten production cycles, and lower long-term manufacturing costs.
Certifications and Compliance
The product holds ISO 9001 quality management system certification and CE industrial safety certification, complying with international silicone material standards for construction and decoration industries. It meets import requirements of global markets, ensuring smooth B2B procurement and customs clearance.
Customization Options
We offer OEM customization services, including adjustable hardness (30-40 Shore A), viscosity (for pouring/brushing), curing speed (via catalyst type), and packaging specifications. We also optimize formulas for specific applications (e.g., complex relief patterns, extreme temperature resistance) to fit Prototype silicone testing and large-scale production.
Production Process
Manufactured with high-purity Silicone raw materials, the product undergoes precise formula blending, closed vacuum mixing, multi-index testing (tensile/tear strength, curing speed), and standardized filling. Each batch is strictly inspected before shipment, supported by mature production lines and professional QC teams, ensuring stable quality for bulk orders.
FAQ
1. How to adjust curing speed? Increase curing agent dosage (up to 4%) for faster curing, reduce (to 1%) for longer working time.
2. Can I add silicone oil? Not recommended, but 5%-10% is allowed for softer molds or complex patterns to ease demolding.
3. When is the best demolding time? 3-5 hours for initial demolding, 24 hours for full curing; set 24h post-demolding before mass use.
4. What’s the storage condition? 12 months at ≤25℃ in sealed, dry cool places.
5. Which application method fits intricate reliefs? Brushing method (high viscosity) for exact pattern replication; pouring for simple patterns.
