HONG YE SILICONE Two Part Silicone Rubber for Molding is a premium Condensation Curing Silicone Mold Rubber, belonging to RTV 2 Silicone Rubber and core Mold Making Silicone. Composed of flowable liquid Part A and curing agent Part B, it features a flexible mixing ratio of 100:2 to 100:5, enabling adjustable hardness. Suitable for both pouring and brushing molding, it boasts high-precision replication, no deformation, excellent tensile/tear strength and easy demolding. Ideal for garden and architectural decoration mold making, it offers good weather, temperature and acid resistance, supporting repeated use. It helps global B2B buyers reduce mold replacement costs and improve production efficiency, adapting to both manual design and batch production.
Product Overview
This professional Industrial mold silicone rubber is a two-component condensed room-temperature curing liquid silicone, tailored for high-quality mold making. As core mold making silicone and liquid silicone, it consists of Part A (base silicone) and Part B (curing agent), with a wide mixing ratio range (100:2-100:5) to meet diverse hardness, viscosity and curing time requirements of different users. It supports both pouring and brushing molding methods, perfectly solving pain points like mold deformation, difficult demolding and low replication precision in decoration mold production. It is a reliable choice for manufacturers engaged in garden decorations, architectural decorations and manual mold design.

Product Features & Advantages
High-precision replication with no deformation ensures consistent pattern and dimensional stability of molds. Excellent tensile and tear strength plus low shrinkage extend mold service life and support repeated use. Easy operation and demolding reduce labor costs and avoid mold damage during demolding. Non-stick and non-oily surface simplifies post-mold cleaning. Dual applicable molding methods (pouring/brushing) fit both simple and intricate pattern molds. Good resistance to weather, temperature, aging and acid ensures stable performance in indoor and outdoor environments. Compared to ordinary silicone, its wide mixing ratio range allows flexible adjustment of hardness/viscosity, adapting to more usage scenarios.
How to Use the Product
Step 1: Prepare the master model. Clean the model thoroughly (use detergent, soapy water or Vaseline as release agent). Weigh 100g base silicone and 2-5g curing agent strictly, then stir evenly. Ensure tools and workbench are clean to avoid curing failure.
Step 2: Conduct vacuum pumping for about 5 minutes (no more than 10 minutes) to remove bubbles; over-pumping will cause cross-linking reaction.
Step 3: Choose molding method: Pouring (for simple patterns, low viscosity, easy flowing/de-airing) or brushing (for delicate patterns/large-size molds, high viscosity, no flowing). Adjust curing agent dosage as needed (more for faster curing/demolding, less for slower).
Step 4: Demold. Demold after proper curing (24 hours is optimal). Curing time and temperature can be adjusted according to on-site conditions.
Application Scenarios
Widely used for garden decoration and indoor/outdoor architectural decoration mold making, including culture stone, artificial stone, concrete block, ornamental concrete/plaster, cement constructions, GRC/GFRC building decorations, GRP/GFRC products, paving stone, fountain, flower pot and other manual mold designs (simple or intricate patterns). It helps buyers improve mold precision and product consistency, reduce mold replacement frequency and shorten production cycles, enhancing overall manufacturing efficiency and cost-effectiveness.
Certifications and Compliance
The product holds ISO 9001 quality management system certification and CE industrial safety certification, complying with international silicone material standards for decoration and construction industries. It meets import requirements of global markets, ensuring smooth customs clearance for B2B procurement.
Customization Options
We offer OEM customization services, including adjustable hardness, viscosity and curing time (via mixing ratio optimization) to fit specific molding needs. Packaging specifications (1kg-200kg) can be customized, and formulas can be optimized for extreme environment resistance, adapting to small-batch manual design and large-scale batch production.
Production Process
Manufactured with high-purity Silicone raw materials, the product undergoes precise formula blending, closed vacuum mixing, multi-index performance testing (tensile/tear strength, curing speed, shrinkage), standardized filling and batch inspection. Each production link is strictly controlled by professional quality teams to ensure stable product performance and consistent quality for bulk orders.
FAQ
1. Can I adjust the mixing ratio freely? Yes, the ratio 100:2-100:5 is adjustable to control hardness and curing speed, but we recommend following the recommended ratio for best performance.
2. What’s the best demolding time? 24 hours after molding is optimal, ensuring full curing and mold durability.
3. Is silicone oil addition allowed? Not recommended, as it may cause oil residue problems on molds.
4. How to store unused silicone? Store at 25℃ in sealed, dry and cool places, with a shelf life of 12 months.
5. Is it suitable for large-size or intricate pattern molds? Yes, brushing method fits delicate/large-size molds, pouring method for simple patterns, meeting diverse needs.
