HONG YE SILICONE Self Leveling Silicone Rubber is a high-performance RTV 2 Silicone Rubber and professional Liquid Mold Silicone, tailored for smooth, efficient casting mold production. This two-component room temperature vulcanized silicone cures at ambient temperature or with heated acceleration, featuring excellent self-leveling, low viscosity and superior bubble release. With moderate hardness, high tear resistance and long reusability, it suits resin crafts, gypsum, concrete and GRC molding, supporting pouring and brushing operations. Available in flexible packaging with a 12-month shelf life, it is a best-selling Mold Making Silicone for global manufacturers and bulk buyers.
Product Overview
This self leveling silicone is a two-part industrial molding silicone rubber, formulated as a user-friendly RTV mold silicone for medium-sized decorative and functional casting projects. Made up of flowable liquid Part A and matched curing agent Part B, it requires no high-temperature equipment for full curing, while heated curing is optional to speed up production cycles. Its automatic self-leveling trait eliminates manual smoothing, creating flawless mold surfaces, and can be modified with additives for brushing fine, intricate patterns, making it a preferred choice for resin craft and gypsum decoration producers worldwide.

Product Features & Advantages
This self leveling silicone boasts automatic leveling performance that cuts operation time and ensures flat, smooth mold surfaces with no manual intervention. Its excellent fluidity fills all fine pattern gaps fully, while strong bubble release eliminates air pockets and mold defects. It has balanced moderate hardness and flexibility for easy demolding, high tensile and tear strength to support hundreds of duplication cycles, extending mold life and lowering material costs. Dual curing options and two operation methods adapt to diverse production needs, boosting overall efficiency and reducing waste.
How to Use the Product
Step 1: Prepare a complete, clean master pattern, fix it firmly on a flat board, and build a tight enclosed frame around it to prevent liquid silicone leakage. Step 2: Weigh Part A and Part B precisely via electronic scale per the fixed ratio, stir slowly and uniformly to avoid partial curing, which shortens mold life and wastes materials.
Step 3: Perform vacuum defoaming for under 10 minutes to remove trapped air, avoid over-vacuuming to prevent premature cross-linking failure.
Step 4: Use pouring for simple patterns, brushing for delicate designs; after demolding, rest the mold for 12 hours before 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 designed for medium-sized products with clear decorative patterns, widely used in craft and building material manufacturing. It helps manufacturers achieve precise pattern replication, maintain consistent product quality, reduce mold replacement frequency, and optimize batch production efficiency effectively.
