HONGYE SILICONE’s liquid silicone for culture stone molds is a professional industrial-grade Addition Curing Silicone, specially developed for manufacturing high-fidelity culture stone molds. As a national high-tech enterprise with standardized production and one-stop solutions, this Mold Making Silicone features excellent fluidity, high tensile strength, and extreme temperature resistance (-60℃~250℃). It precisely replicates natural stone textures, supports multiple mold turns, and is easy to operate, helping global building materials and mold manufacturers reduce costs, improve production efficiency, and produce high-quality, realistic culture stone products for construction and decoration markets.
Product Overview
Our liquid silicone for culture stone molds is a two-component RTV 2 Silicone Rubber, composed of flowable Part A and Part B, designed exclusively for culture stone mold production. This Industrial mold silicone rubber is easy to operate, supporting both room-temperature and heat curing, making it suitable for mass production of various culture stones (natural stone, artificial stone, decorative stone). Unlike ordinary silicone, it enables deep curing without being limited by mold thickness, ensuring uniform hardness and durability. It is widely used in concrete, epoxy resin, and polyester resin culture stone mold manufacturing, and also applies to precision Prototype silicone and large cement component mold making, providing a versatile solution for global buyers.

Product Features & Advantages
1. High Fidelity Replication: Superior fluidity penetrates every detail of natural stone textures (grain, texture, uneven surface), perfectly reproducing realistic culture stone appearances, meeting high-end decoration needs.
2. Excellent Durability: High tensile and tear resistance, molds made from this Liquid Mold Silicone support 60~90 mold turns, reducing replacement costs and improving production efficiency. 3. Flexible Operation: 1:1 mix ratio, room/heat curing options, and customizable operating/curing time, adapting to different production scales and mold sizes.
4. Strong Adaptability: Resists high and low temperatures, moisture, and corrosion, suitable for indoor and outdoor culture stone production, and compatible with concrete, epoxy resin, polyester resin materials.
5. Deep Curing Performance: No limitation by mold thickness, ensuring uniform curing and stable performance of large-sized culture stone molds.
6. Customizable Formulation: Tailor hardness, color, and curing parameters to match different culture stone styles and production requirements.
How to Use (Step-by-Step)
1. Mix Components: Combine Part A and Part B in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes until the mixture is uniform and free of streaks or air bubbles.
2. Vacuum Degassing: Perform vacuum degassing on the mixed silicone for 2~5 minutes; adjust time according to silicone viscosity, weight, and vacuum strength to eliminate all bubbles (critical for texture replication).
3. Pour & Fill: Slowly pour the degassed silicone into the culture stone master mold, ensuring full coverage of all textures and contours.
4. Cure: Cure at room temperature (4~5 hours) or heat at 80~120℃ for accelerated curing (tens of minutes) until fully set.
5. Demold & Store: Gently demold the silicone mold, clean it for reuse; store unused silicone sealed indoors, away from sunlight and rain.
