HONG YE SILICONE Flowable Liquid Moulding RTV Silicone is a high-performance two-component RTV 2 Silicone Rubber, available in Platinum cured mold silicone (1:1/10:1) and Condensation Curing Silicone Mold Rubber. As premium Mold Making Silicone and liquid silicone , it features 5–65 Shore A adjustable hardness, exceptional fluidity and low shrinkage (<3‰). With high tensile/tear strength, high temperature resistance and multiple duplication cycles, it suits fine precision products and large molds alike. Offering 2%–5% curing agent adjustment for flexible operation/curing times, it supports resin crafts, ceramic sculptures and epoxy resin molding, reducing defects and improving production efficiency for global B2B buyers.
Product Overview
This specialized Industrial mold silicone rubber is engineered for flowable molding, designed to replicate intricate details and adapt to diverse product sizes. It is a two-part room-temperature vulcanization product (Part A: flowable liquid silicone, Part B: curing agent), covering dual curing systems to meet cost and performance needs. Its ultra-low shrinkage ensures dimensional accuracy, while adjustable hardness (5–65 Shore A) fits fine-pattern small products (low hardness) and large-scale molds (high hardness). With 30-minute operational time and 2–8-hour demolding cycle (based on curing agent dosage), it is a top-choice for craft gifts, toys and resin product manufacturers, complemented by professional technical support for silicone model making.

Product Features & Advantages
Exceptional fluidity ensures full filling of complex mold cavities, capturing ultra-fine product details. Adjustable hardness (5–65 Shore A) adapts to fine precision items and large-scale molds. Low shrinkage (<3‰) guarantees consistent dimensional stability across batches. High tensile/tear strength and temperature resistance enable repeated use and long mold lifespan. Flexible curing agent dosage (2%–5%) adjusts operational time (10mins–2.5hrs) and demolding cycle (1–8hrs) for diverse production needs. Dual curing systems offer cost-effective (condensation) and high-performance (platinum) options. Acid/alkali resistance enhances compatibility with various casting materials, supported by professional technical guidance.
How to Use the Product
Step 1: Prepare the prototype and molding frame, fix the prototype firmly; apply release agent for glass/ceramic prototypes to prevent sticking.
Step 2: Select platinum/condensation silicone, weigh Part A and curing agent (2%–5% for condensation, 1:1/10:1 for platinum), stir evenly.
Step 3: Avoid adding silicone oil unless necessary; add 5%–10% only for ultra-soft molds or complex patterns.
Step 4: Perform vacuum defoaming, pour the mixed silicone into the frame, and cure at room temperature.
Step 5: Demold after 1–8 hours (based on curing agent dosage), and use the mold after full stabilization.
Application Scenarios
Widely used for resin gifts, resin crafts/sculptures, epoxy/acrylic/polyester resin product molds, ceramic sculptures, toy gifts, craftwork gifts and precision part molding. Suitable for craft gift factories, toy manufacturers, resin product workshops and ceramic studios. It helps buyers reduce defective rates via precise detail replication, shorten production cycles with adjustable curing speed, and lower mold replacement costs through durable performance, enhancing market competitiveness.
Certifications and Compliance
The product complies with ISO 9001 quality management system and CE industrial standards. Platinum cured Mold Silicone meets FDA/EU Food grade mold silicone requirements for indirect food contact applications. All formulas conform to international chemical transportation and import regulations, supporting smooth cross-border bulk procurement.
Customization Options
Support hardness customization (5–65 Shore A), viscosity adjustment, color customization (white/red/other) and curing speed optimization. Provide formula modification for special scenarios (ultra-fine details, extra-large molds). Customize packaging specifications (small sample jars to industrial drums) and mixing ratios to match production lines, meeting personalized B2B needs.
Production Process
Adopt high-purity Silicone raw materials, go through precise proportioning, closed vacuum mixing (to maintain fluidity and avoid bubbles), multi-index testing (hardness, shrinkage, tensile strength), automatic filling and sealed packaging. Each batch undergoes strict quality inspection, with mature production lines ensuring consistent quality and on-time delivery for large orders.
FAQ
Q1: How to adjust curing speed?
A1: For condensation silicone, 1% curing agent = 6–8hr demolding; 2% = 2–3hr; 3% = 1.5–2hr; 4% = 1–1.5hr. Platinum silicone follows 1:1/10:1 ratio for fixed curing time.
Q2: Which hardness for fine vs. large products?
A2: 5–25 Shore A for fine precision patterns; 30–65 Shore A for large-size molds.
Q3: Is silicone oil necessary?
A3: Not recommended; add 5%–10% only for ultra-soft molds or complex patterns.
Q4: Can it be used for epoxy resin molding?
A4: Yes, it is ideal for epoxy, acrylic and polyester resin product molds.
Q5: What is the shelf life?
A5: 12 months when stored in original sealed packages at ≤25℃ in dry, cool places.
