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, resin toys, 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, with tin-based condensation curing technology to balance performance and cost. It is a two-part flowable liquid product (Part A: base silicone, Part B: curing agent), requiring no special equipment for room-temperature vulcanization. Its optimized fluidity ensures full filling of complex and decorative mold cavities, making it a popular choice for small-size delicate products with intricate surface patterns. The product’s versatility and cost-effectiveness make it ideal for crafts, toys and daily chemical product manufacturers.

Product Features & Advantages
Adjustable hardness (5-50 Shore A) fits diverse scenarios—low hardness for ultra-fine patterns, high hardness for simple-shaped products. Exceptional fluidity and low viscosity enable smooth pouring, fully replicating complex decorative patterns on product surfaces. Room-temperature curing saves energy and simplifies production, reducing equipment investment. Good tensile and tear strength extends mold service life, supporting multiple duplication cycles and lowering replacement costs. Cost-effective tin-based formula meets mass production needs without compromising performance. Easy operability and demolding reduce labor costs and improve production efficiency. Low shrinkage guarantees consistent dimensional stability of cast products across batches.
How to Use the Product
Step 1: Prepare the small-size prototype with fine patterns and molding frame, fix the prototype firmly; apply release agent for glass/ceramic prototypes to prevent sticking.
Step 2: Weigh Part A and curing agent at 100:3 ratio, stir evenly for 2-3 minutes to ensure full mixing.
Step 3: Perform vacuum defoaming for 1-2 minutes to eliminate air bubbles (critical for pattern clarity).
Step 4: Pour the mixed silicone into the frame, ensuring full coverage of all intricate details.
Step 5: Cure at 25℃ for 3-6 hours (full curing), demold gently and use the mold for casting (resin, candle, soap, etc.).
Application Scenarios
Widely used for making molds for crafts, giftware with fine/decorative patterns, resin toys, candles, soaps, sculptures, statues and small delicate artworks. Ideal for craft workshops, resin toy factories, candle/soap manufacturers, gift customization enterprises and sculpture studios. The product helps buyers improve product appearance quality (fine pattern replication), reduce defective rates by 20%+, shorten production cycles via easy operation, and lower comprehensive production costs with its cost-effective formula, enhancing market competitiveness.
Certifications and Compliance
The product complies with ISO 9001 quality management system and CE industrial standards. All formulas conform to international chemical transportation and import requirements, supporting smooth cross-border B2B bulk procurement. It meets industrial safety standards for mold making materials, ensuring safe production and use.
Customization Options
Support customization of hardness (5-50 Shore A) to adapt to different pattern complexities and product types. Provide viscosity adjustment for faster/smoother pouring or thicker coating needs. Customize curing speed (2-8hrs) to match production efficiency. Offer packaging specification customization (small sample jars for testing, large drums for mass production) according to buyer needs.
Production Process
Adopt high-purity Silicone raw materials and premium tin-based curing agents, go through precise proportioning, closed vacuum mixing (to maintain fluidity and avoid bubbles), multi-index testing (hardness, tensile strength, shrinkage rate, curing speed), automatic filling and sealed packaging. Each batch undergoes strict quality inspection to ensure consistent performance. Mature production lines and sufficient inventory guarantee on-time delivery for both small-batch and bulk orders.
FAQ
Q1: What hardness is suitable for products with ultra-fine patterns?
A1: 5-20 Shore A is optimal, as it ensures full pattern replication and easy demolding.
Q2: Can this silicone be used for resin toy mass production?
A2: Yes, its cost-effective formula and good duplication performance are perfect for resin toy mass production.
Q3: How to store the product to extend shelf life?
A3: Store in original sealed packages at ≤25℃ in dry and cool places, avoiding direct sunlight and high temperature.
Q4: Do I need a release agent for resin prototypes?
A4: No, porous materials like resin do not require it; release agent is only needed for smooth non-porous surfaces.
Q5: Can the curing time be shortened?
A5: Yes, increase ambient temperature to 30-35℃ (shortens curing to 2-3hrs); do not exceed recommended mixing ratio.
