HONG YE SILICONE Self Leveling Silicone Rubber is a reliable RTV 2 Silicone Rubber and industrial-grade Liquid Mold Silicone, built for efficient casting mold fabrication. This two-component room temperature vulcanized silicone cures at ambient or heated temperatures, boasting superior self-leveling performance, excellent fluidity and fast bubble release. With moderate hardness, strong tensile and tear resistance, and long reusable lifespan, it works for resin crafts, gypsum, concrete and GRC molding, supporting both pouring and brushing operations. Available in multiple packaging sizes with a 12-month shelf life, it is our best-selling Mold Making Silicone for global craft and manufacturing buyers.
Product Overview
This self leveling silicone is a two-part condensation curing silicone mold rubber, designed as a user-friendly RTV mold silicone for versatile casting applications. It consists of flowable liquid Part A and specialized curing agent Part B, requiring no complex equipment for room temperature curing, while heated curing is optional to speed up production cycles. Tailored for medium-sized patterned products, it delivers smooth, bubble-free mold surfaces automatically, and can be adjusted for brushing use with targeted additives, making it the top choice for resin craft factories and gypsum decoration manufacturers seeking efficient, high-quality molding solutions.

Product Features & Advantages
This self leveling silicone features automatic leveling performance that eliminates manual smoothing, cutting down operation time and ensuring flawless mold surfaces. Its exceptional fluidity penetrates all pattern details easily, paired with outstanding bubble release to avoid air pockets and defective molds. It offers moderate hardness, high tensile and tear strength for repeated duplication, flexible curing options, and dual operation methods to fit both simple and intricate patterns. Easy demolding and good flexibility extend mold service life, reducing material waste and overall production costs for batch manufacturing.
How to Use the Product
Step 1: Prepare the intact master pattern, fix it firmly on a flat board, and build a sealed frame around it to hold the liquid silicone. Step 2: Weigh Part A and Part B accurately with an electronic scale following the fixed ratio, stir thoroughly and evenly to prevent partial curing and shortened mold lifespan. Step 3: Perform vacuum defoaming for less than 10 minutes to remove trapped air, avoid over-vacuuming to prevent premature cross-linking failure. Step 4: Use pouring for simple patterns (low viscosity for smooth flow) or brushing for delicate details (adjusted viscosity to prevent runoff); fully cure, demold, and let the mold rest for 12 hours before formal mass production.
Application Scenarios
This liquid mold silicone is widely applied to make casting molds for concrete stone, GRC, gypsum decorations, plaster ornaments, fiberglass products, polyester crafts, unsaturated resin, polyresin, polyurethane, bronze, wax and candle items. It is specially optimized for medium-sized products with clear patterns, highly recognized by resin craft and gypsum decoration manufacturers worldwide. It enables precise pattern replication, improves production efficiency, ensures consistent product quality, and lowers mold replacement costs, adapting to diverse casting materials and manufacturing scenarios.

FAQ
Q1: Does this silicone need heating to cure completely?
A1: No, it cures fully at room temperature; heating is only optional to shorten curing time for urgent orders.
Q2: Can this silicone be used 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 A and B in the wrong ratio?
A3: Incorrect ratio leads to too fast curing, uneven solidification, short mold life and material waste.
Q4: How should I store this silicone to keep it valid?
A4: Store in sealed original packaging, cool and dry place below 25℃, valid for 12 months.
Q5: Do you offer trial samples before bulk purchase?
A5: Yes, we provide free samples for testing to confirm product fit for your production needs.
