Key Sentences：RTV-2 two-component liquid mold silicone, with excellent texture reproduction and tear resistance, solves the industry pain points of easy damage and loss of details in the replication of complex reliefs and special-shaped sculptures.

In recent years, the domestic cultural and creative industry, decorative crafts and art sculpture market have achieved steady growth. Consumers have continuously raised requirements for the detail texture and shape diversity of crafts. Demand for European-style reliefs, cartoon sculptures, resin ornaments and art handworks keeps rising, forcing the whole craft industry chain to carry out technical iteration in mold making. In traditional molding processes, gypsum and simple resin molds have shortcomings such as high brittleness, poor detail restoration and limited molding times. It is difficult to meet the production requirements of complex special-shaped crafts and deep relief products. The popularization of high-performance liquid mold silicone for crafts is reshaping the molding production process of crafts.

Liquid mold silicone for crafts is a two-component room temperature vulcanized RTV-2 silicone rubber. It can complete vulcanization and forming at room temperature without high-temperature heating, suitable for small-batch sampling in hand workshops and mass mold opening in craft factories. This type of liquid silicone has good fluidity. After mixing and stirring, it can fully wet the surface of the prototype, capture fine lines and concave-convex relief texture on the sculpture surface. Even millimeter-level fine patterns can be completely reproduced, retaining the creative details of the art prototype to the maximum, which is the core advantage of its rapid popularization in the field of cultural and creative sculptures.

In terms of material performance, high-quality liquid mold silicone for crafts has outstanding tear strength and elongation. Sculptures and relief crafts often contain a large number of undercuts and deep grooves. Such shapes are easy to pull and tear the mold during demolding. Low-cost traditional silicone molds usually crack, chip and deform after more than ten times of molding. However, high-performance mold silicone has excellent elasticity after curing, and can quickly rebound after stretching, greatly extending mold service life. A qualified silicone mold can stably complete dozens of casting productions, significantly sharing the mold opening cost of a single craft. Meanwhile, the linear shrinkage rate of the product is controlled within 0.3%, the dimensional stability of the mold is strong, and there will be no dimensional deviation of finished products during mass production, ensuring the consistency of craft outputs.

From the perspective of operation process, this molding material has a friendly operation threshold, and the curing speed can be fine-tuned according to ambient temperature. Small crafts generally adopt the pouring method to make molds; for large sculptures and large-area reliefs, the brush molding process is adopted, with fiberglass cloth as the reinforcing layer to improve the overall structural strength of the mold. The raw materials can be formulated into various colors with flexible hardness range. The hardness from 20A to 35A can make soft and easy-demolding molds for fine small parts, or molds with stronger support for large sculptures. After curing, the mold surface has good natural release effect. Casting materials such as resin and gypsum are not easy to stick to the mold. The crafts after demolding have smooth surface, reducing subsequent polishing and repairing procedures and saving labor time.

From the perspective of industry trends, the craft market is moving toward personalized customization and flexible production. In the past, craft production was mostly mass standardized products. Nowadays, orders for niche cultural creations and custom sculptures are increasing year by year, featuring small batches, multiple styles and fast updates. Traditional hard molds have long mold opening cycles and high modification costs, which are difficult to adapt to the demand of flexible production. Liquid mold silicone features short mold opening cycle. After the prototype is modified, the mold can be remade quickly, perfectly matching the development trend of fast new product launch and customized order receiving in the cultural and creative industry.

At the same time, material manufacturers are continuously optimizing product formulas, further balancing three core indicators: fluidity, tear resistance and working time, reducing the probability of bubbles and molding defects. In terms of environmental protection, the formula of industrial-grade liquid mold silicone for crafts is continuously upgraded to reduce volatile substances and meet the safety production requirements of craft workshops.
