HONG YE SILICONE Concrete Stamp Silicone Rubber is a professional Industrial mold silicone rubber designed for concrete embossing and stamping. As premium Mold Making Silicone and liquid silicone, it features excellent fluidity, high temperature resistance, acid-alkali resistance and low shrinkage. With strong tensile and tear strength, it supports repeated turnover, ensuring concrete stamps retain clear patterns. Ideal for municipal engineering, residential areas and commercial spaces, it helps global B2B buyers reduce costs, improve construction efficiency and create high-quality embossed concrete surfaces.
Product Overview
This specialized RTV 2 Silicone Rubber is tailor-made for concrete stamping and embossing, engineered to replicate natural surfaces (cobblestones, brickwork, flagstones, wood) with high precision. As a two-component flowable liquid silicone, it combines easy operability with long service life, resisting aging, high temperatures and chemical corrosion. Its ultra-low shrinkage ensures concrete stamp molds do not expand or deform, maintaining pattern integrity through repeated use. It is the ideal choice for contractors, municipal engineering companies and building material suppliers seeking cost-effective, durable concrete stamping solutions.

Product Features & Advantages
High fluidity ensures easy operation, fully filling mold details for clear, realistic concrete patterns. Excellent high temperature, acid and alkali resistance adapts to outdoor construction environments, resisting aging and extending service life. Strong tensile and tear strength supports multiple turnover uses, reducing mold replacement costs. Ultra-low shrinkage prevents mold expansion and deformation, ensuring consistent pattern replication. Compared to competitors, it has better durability and pattern retention, suitable for long-term outdoor use. Economical alternative to natural stone paving, cutting construction time and costs while maintaining high-quality appearance.
How to Use the Product
Step 2: Mix Part A and Part B at 1:1 weight ratio, stir evenly for 2-3 minutes.
Step 3: Conduct vacuum defoaming for 1-2 minutes to eliminate air bubbles.
Step 4: Pour the mixed silicone into the concrete stamp prototype, fully covering all pattern details.
Step 5: Cure at 25℃ for 4-6 hours, or heat to accelerate curing; demold gently after full curing.
Step 6: Test the mold with concrete to verify pattern clarity before formal construction.
Application Scenarios
Widely used in over 60 scenarios, including municipal engineering, scenic spots, amusement parks, schools, residential quarters, villas, courtyards, commercial pedestrian streets, hotels, resorts and squares. Used to produce embossed floors, concrete stamps, pavement embossing and cement embossed floors, adding unique flair to driveways, pool decks, patios, walkways and walls. It replicates patterns like aged cobblestones, brickwork, flagstones, slate tile, marble, granite and wood. Ideal for contractors, municipal engineering companies, building material suppliers and landscape design firms, helping reduce construction costs by 30%+ and improve efficiency.
Certifications and Compliance
Complies with ISO 9001 quality management system and CE industrial standards. Meets international building material safety regulations, resistant to outdoor harsh environments. All formulas conform to international chemical transportation and import regulations, supporting smooth cross-border B2B bulk procurement.
Customization Options
Supports pattern customization to replicate any natural surface (cobblestones, wood, marble). Provides hardness adjustment (25-40 Shore A) for different concrete types. Optimizes curing speed to match construction schedules. Offers formula modification for enhanced acid-alkali resistance or high-temperature tolerance. Customizes packaging from small test jars to industrial bulk drums.
Production Process
Adopts high-purity Silicone raw materials and anti-aging additives, undergoes precise proportioning, closed-loop vacuum mixing, multi-index testing (fluidity, shrinkage, tensile strength), automatic filling and sealed packaging. Each batch is tested with concrete samples to ensure pattern replication accuracy, with mature production lines guaranteeing on-time delivery for small-batch and bulk orders.
