Product Features & Advantages
Ultra-low shrinkage (≤2‰) guarantees high mold precision, ensuring consistent replication of plaster decorations. High tensile and tear strength enhances durability, allowing multiple reuses and reducing mold replacement costs. High temperature and chemical resistance ensure stable performance in various industrial and craft environments. Dual curing options (platinum/tin cure) cater to different budget ranges and precision requirements. Excellent fluidity and operational flexibility make molding and demolding easy, even for complex patterns. Curing speed is adjustable via 2-5% curing agent ratio, adapting to diverse production schedules. Compared to competitors, it offers lower shrinkage, higher reusability and better plaster mold adaptability.
How to Use the Product
Step 1: Select the right hardness: high-hardness RTV mold silicone for large products or molds; low-hardness silicone for fine, precision-pattern molds.
Step 2: Add 2-5% curing agent (Part B) to Part A, adjusting the ratio based on production needs (1%: 2.5h operation time, 6-8h demolding; 2%: 50min-1h operation, 2-3h demolding; 3%: 28-30min operation, 1.5-2h demolding; 4%: 10-15min operation, 1-1.5h demolding).
Step 3: Mix Part A and Part B thoroughly to achieve uniform consistency.
Step 4: Pour or brush the mixed silicone onto the original mold, ensuring full coverage of all details.
Step 5: Demold after the specified time, then use the mold for plaster product duplication.
Application Scenarios
Widely applied for mold duplication of ornamental plaster products and decorations, such as plaster cornice, plaster ceilings, plaster ceiling rose, ceiling rings and more. It is also suitable for manufacturing precision molds. As high-quality Industrial mold silicone rubber, it serves craft workshops, plaster decoration factories, mold manufacturers and gift production enterprises. It helps buyers improve mold precision, reduce material waste, extend mold service life and boost overall production efficiency.
Certifications and Compliance
Complies with ISO 9001 quality management system and CE industrial standards, ensuring stable performance and safe operation. Meets international chemical transportation and import regulations, with vacuum packaging supporting smooth cross-border bulk procurement. All formulas are non-toxic and environmentally friendly, suitable for long-term industrial and craft applications.
Customization Options
Offers hardness customization (high/low) to fit large products or precision-pattern molds. Adjusts curing speed through curing agent ratio to match specific production rhythms. Provides two curing system options (platinum/tin cure) for different budget and precision needs. Delivers flexible packaging specifications (1kg to 200kg) for small test orders or large bulk purchases. Vacuum packaging customization is also available.
Production Process
Uses high-purity Silicone raw materials, undergoes precise proportioning of Part A and Part B, closed-loop mixing, multi-index performance testing (shrinkage, tensile strength, fluidity) and vacuum-sealed packaging. Each batch is strictly inspected to ensure ultra-low shrinkage and stable performance, with mature production lines guaranteeing on-time delivery for both small-batch and bulk orders.
