Product Features & Advantages
High fluidity enables easy operation, ensuring the silicone fully fills mold details to create clear, lifelike concrete patterns. Excellent high temperature, acid and alkali resistance makes it adaptable to harsh outdoor construction environments, resisting aging and prolonging mold service life. Strong tensile and tear strength supports multiple repeated uses, reducing mold replacement frequency and lowering costs. Ultra-low shrinkage prevents mold expansion and deformation, ensuring consistent pattern replication for each stamping. Compared with competitors, our product has better durability and pattern retention, suitable for long-term outdoor application. It is an economical alternative to natural stone paving, reducing construction time and material costs while achieving the same high-end appearance as natural stone.
How to Use the Product
Step 2: Mix Part A (silicone base) and Part B (curing agent) at a 1:1 weight ratio, stirring evenly for 2-3 minutes to ensure full integration.
Step 3: Perform vacuum defoaming for 1-2 minutes to eliminate air bubbles, ensuring the mold surface is smooth and pattern details are complete.
Step 4: Slowly pour the mixed silicone into the concrete stamp prototype, fully covering all pattern details without omissions.
Step 5: Cure at 25℃ room temperature for 4-6 hours, or use heating curing to accelerate the process; demold gently after full curing to avoid damaging the mold.
Step 6: Conduct a concrete test stamping to verify pattern clarity and mold usability before formal large-scale construction.
Application Scenarios
It is widely applied in more than 60 scenarios, including municipal engineering, scenic spots, amusement parks, schools, residential quarters, villas, courtyards, commercial pedestrian streets, hotels, resorts, squares, museums and gymnasiums. It is used to produce embossed floors, concrete stamps, pavement embossing and cement embossed floors, adding unique aesthetic appeal to driveways, pool decks, patios, walkways and walls. It can replicate various natural patterns such as aged cobblestones, brickwork, flagstones, slate tile, marble, granite and wood. Ideal for contractors, municipal engineering companies, building material suppliers and landscape design firms, it helps reduce construction costs by more than 30% and improve construction efficiency significantly.
Certifications and Compliance
The product complies with ISO 9001 quality management system and CE industrial standards, ensuring stable and reliable quality. It meets international building material safety regulations, with strong resistance to outdoor harsh environments such as sunlight, rain and temperature changes. All formulas conform to international chemical transportation and import regulations, supporting smooth cross-border B2B bulk procurement and long-term supply cooperation.
Customization Options
We support pattern customization to accurately replicate any natural surface, including cobblestones, wood, marble, slate tile and brickwork. Provide hardness adjustment (25-40 Shore A) to adapt to different concrete types and stamping requirements. Optimize curing speed according to customer construction schedules to improve work efficiency. Offer formula modification to enhance acid-alkali resistance or high-temperature tolerance for special construction environments. Customize packaging specifications from small test jars (1kg) to industrial bulk drums (200kg) based on order volume.
Production Process
Adopting high-purity Silicone raw materials and high-quality anti-aging additives, the product undergoes precise proportioning, closed-loop vacuum mixing (to ensure fluidity and avoid air bubbles), multi-index performance testing (including fluidity, shrinkage rate, tensile strength and acid-alkali resistance), automatic filling and sealed packaging. Each batch of products is tested with concrete samples to ensure pattern replication accuracy and stable performance. Mature production lines and sufficient inventory guarantee on-time delivery for both small-batch test orders and large-scale bulk orders.
FAQ
Q1: How many times can the concrete stamp mold be reused?
A1: With proper maintenance (cleaning and sealed storage after use), it can be reused 100-150 times, thanks to its strong tensile and tear strength.
Q2: Is this silicone suitable for outdoor concrete paving projects?
A2: Yes, it has excellent anti-aging, acid-alkali resistance and weatherproof performance, perfectly adapting to outdoor long-term use.
Q3: Can it replicate complex and delicate natural stone patterns?
A3: Yes, its high fluidity can fully fill the fine details of the prototype, realizing accurate replication of complex natural patterns.
Q4: How to adjust the curing time in cold weather?
