HONG YE SILICONE RTV2 Silicone for Molds Replication is a two-component Liquid Mold Silicone, also known as RTV 2 Silicone Rubber, including Platinum cured mold silicone and Condensation Curing Silicone Mold Rubber. It features exceptional fluidity and simple operability, cures rapidly at room temperature, with low shrinkage and excellent tear resistance. Supporting pouring and brushing molding processes, it is widely used for industrial craft molds and food-safe mold making, enabling high repeat replication times and stable, high-precision molding results for global buyers.
Product Overview
This RTV2 silicone is a professional Mold Making Silicone dedicated to efficient molds replication, divided into two high-practicality curing systems to meet diverse production needs. The platinum Addition Curing Silicone adopts 1:1/10:1 mixing ratio, suitable for high-detail molds and food-grade applications; the tin-cured type uses 100:3 ratio, perfect for cost-efficient industrial mold production. With great fluidity and easy demolding performance, this liquid silicone is ideal for rapid prototyping and batch molding, covering various casting and replication scenarios.

Product Features & Advantages
This RTV2 mold silicone is made of flowable Liquid silicone rubber with matched curing agent, ensuring smooth and easy operation for both pouring and brushing molding, and effortless demolding without damaging master models or molds. It cures completely at room temperature within 2-4 hours, shortening production cycles and improving work efficiency. Featuring high tensile and tear strength and ultra-low shrinkage, it perfectly reproduces fine details of masters, supports high replication times to reduce mold costs. The food-grade version is non-toxic, odorless and FDA compliant, safe for making food molds.
How to Use the Product
Step 1: Choose platinum cure or tin cure RTV2 silicone based on production needs and mold precision requirements, clean the master model thoroughly to remove dust, oil and impurities.
Step 2: Weigh component A and component B accurately according to the specified mixing ratio, stir fully and evenly to remove bubbles and stratification.
Step 3: Apply the well-mixed silicone to the master model by pouring or brushing, ensuring full and even coverage of the model surface.
Step 4: Place the mold at room temperature and let it stand for 2-4 hours until it is fully cured and forms a stable elastomer.
Step 5: Demold carefully to obtain a high-precision replica mold, which can be used for subsequent casting and production.
Application Scenarios
This RTV2 silicone is mainly used for making elastic molds for molds replication, widely applied to concrete stones, wax molds, PU molds, resin crafts, gypsum casting, candle molding and other industrial fields.
