HONG YE SILICONE Self Leveling Silicone Rubber is a versatile RTV 2 Silicone Rubber and industrial Liquid Mold Silicone, engineered for hassle-free casting mold production. This two-component room temperature vulcanizing silicone cures at ambient temperature or with gentle heat, boasting great self-leveling ability, low viscosity for easy flow and fast bubble release. With balanced moderate hardness, strong tear resistance and long reusable life, it works perfectly for resin crafts, gypsum, concrete and GRC mold making, supporting both pouring and brushing applications. Available in multiple practical packaging sizes with a 12-month shelf life, it is our top-selling Mold Making Silicone for global small workshops and large manufacturers.
Product Overview
This self leveling silicone is a user-friendly two-part molding silicone rubber, designed as a reliable RTV mold silicone for everyday casting needs. It features a flowable base component and a matched curing agent, requiring no complicated tools for room temperature curing, while heated curing is optional to speed up production for tight deadlines. Built specifically for medium-sized patterned products, it levels out automatically to create smooth mold surfaces without manual adjustment, and can be modified with additives for brushing fine details, making it a go-to choice for resin craft and gypsum decoration producers worldwide.

Product Features & Advantages
This self leveling silicone eliminates the need for manual leveling thanks to its automatic spreading formula, cutting down operation time and ensuring flawless, smooth mold surfaces. Its thin, smooth fluidity fills every fine pattern gap completely, while strong bubble release properties prevent air pockets and defective molds. It has a balanced moderate hardness that is flexible enough for easy demolding and tough enough for repeated use, with high tensile and tear strength to extend mold lifespan. Dual curing options and two operation methods make it adaptable to all common casting projects, reducing material waste and boosting production efficiency.
How to Use the Product
Step 1: Prepare your clean, intact master pattern, secure it firmly to a flat board, and build a tight frame around it to contain the liquid silicone and prevent spills. Step 2: Weigh Part A and Part B precisely with an electronic scale following the recommended ratio, stir slowly and thoroughly in one direction to ensure full mixing — uneven mixing causes partial curing and shortens mold life. Step 3: Vacuum the mixed silicone for under 10 minutes to remove trapped air, avoid over-vacuuming to stop premature curing. Step 4: Use pouring for simple designs, brushing for intricate details; after demolding, let the mold cure for an extra 12 hours before starting mass production.
Application Scenarios
This liquid mold silicone is widely used to make casting molds for concrete stone, GRC, gypsum decorations, plaster ornaments, fiberglass, polyester crafts, unsaturated resin, polyresin, polyurethane, bronze, wax and candle products. It is specially optimized for medium-sized decorative items with clear patterns, and is highly popular among resin craft factories and gypsum decoration manufacturers. It helps businesses achieve precise pattern replication, maintain consistent product quality, lower mold replacement costs, and run efficient batch production with minimal operational issues.
Certifications and Compliance
Our self leveling silicone rubber meets ISO 9001 quality standards and holds CE certification, being non-toxic, odorless and eco-friendly. It complies with international industrial molding safety requirements, is classified as non-hazardous, and follows all global chemical import, export and shipping rules, making it suitable for bulk procurement by international craft, building material and decoration manufacturers.
Customization Options
We offer hardness customization to fit different product sizes, pattern details and production needs. Provide additive adjustments to convert the silicone for brushing applications, optimizing viscosity to prevent runoff. Supply flexible packaging from 1kg sample bottles for testing to 200kg bulk drums for large-scale production, and can adjust curing speed to match room or heated curing workflows.
Production & Customer Support
We use high-purity Silicone raw materials and precise formula blending, with strict batch quality checks to guarantee consistent fluidity, hardness and curing performance. We offer free sample testing so customers can verify product suitability before placing bulk orders, reducing procurement risks. Our technical team provides full operation guidance to help users avoid common mistakes and get the longest life from each mold.
FAQ
Q1: Does this silicone need heat to cure fully?
A1: No, it cures completely at room temperature; heat is only used to speed up curing for urgent orders.
Q2: Can I use this silicone for both pouring and brushing?
A2: Yes, it works for pouring directly, and can be adjusted with additives for brushing delicate patterns.
Q3: What happens if I mix the ratio wrong?
A3: Incorrect mixing ratio leads to fast/slow curing, uneven solidification, short mold life and wasted silicone.
Q4: How should I store this silicone?
A4: Keep it sealed in its original package, in a cool, dry place below 25℃, shelf life is 12 months.
Q5: Do you offer trial samples?
A5: Yes, we provide free samples for testing to confirm it fits your production needs before bulk buying.
