HONG YE SILICONE Tin Cure Molding Silicone Rubber is a cost-effective two-component RTV 2 Silicone Rubber, belonging to Condensation Curing Silicone Mold Rubber. As professional Mold Making Silicone and liquid silicone , it features adjustable hardness (5-50 Shore A), low viscosity, exceptional fluidity and room-temperature curing (25℃, 3-6hrs). With good tensile/tear strength and low shrinkage, it excels at replicating fine patterns for small delicate products. Suitable for crafts, Toy mold silicone, candles, soaps and sculptures, it offers easy operability and demolding, helping global B2B buyers reduce production costs and improve molding efficiency.
Product Overview
This specialized Industrial mold silicone rubber is engineered for fine-pattern molding, adopting tin-based condensation curing technology to balance performance and cost. It is a two-part flowable liquid (Part A: base silicone, Part B: curing agent), requiring no special equipment for vulcanization. Its optimized fluidity ensures full filling of complex decorative cavities, making it a popular choice for small-size products with intricate surfaces. Versatile and cost-efficient, it’s ideal for crafts, resin toy and daily chemical product manufacturers.

Product Features & Advantages
Adjustable hardness (5-50 Shore A) fits diverse needs—low hardness for ultra-fine patterns, high hardness for simple shapes. Exceptional fluidity & low viscosity enable smooth pouring and precise detail replication. Room-temperature curing saves energy and reduces equipment investment. Good tensile/tear strength extends mold service life, lowering replacement costs. Cost-effective tin-based formula suits mass production. Easy operability & demolding cut labor costs. Low shrinkage ensures consistent dimensional stability across batches, outperforming inferior counterparts in pattern fidelity.
How to Use the Product
Step 1: Prepare small-size prototype (with fine patterns) and molding frame, fix firmly; apply release agent for glass/ceramic prototypes.
Step 2: Weigh Part A and curing agent at 100:3 ratio, stir evenly for 2-3 minutes.
Step 3: Vacuum defoam for 1-2 minutes to eliminate bubbles.
Step 4: Pour mixed silicone into the frame, ensuring full coverage of intricate details.
Step 5: Cure at 25℃ for 3-6 hours, demold gently and start casting (resin, candle, etc.).
Application Scenarios
Widely used for molds of crafts, giftware (fine decorative patterns), resin toys, candles, soaps, sculptures and small delicate artworks. Ideal for craft workshops, toy Mold Silicone manufacturers, candle/soap factories and gift customization enterprises. It helps buyers improve product appearance (fine pattern replication), reduce defective rates by 20%+, shorten production cycles and lower costs, enhancing market competitiveness.
Certifications and Compliance
Complies with ISO 9001 quality management system and CE industrial standards. All formulas meet international chemical transportation and import regulations, supporting smooth cross-border B2B bulk procurement. Conforms to industrial safety standards for mold making materials, ensuring safe production.
Customization Options
