HONG YE SILICONE RTV Silicone for Urethane Furniture Molds is a professional-grade RTV 2 Silicone Rubber designed exclusively for making durable, high-precision molds for urethane furniture parts. As a versatile Liquid Mold Silicone and Industrial mold silicone rubber, it comes with two curing options — Addition Curing Silicone and condensation curing silicone — and cures fully at room temperature. Boasting zero shrinkage, high tear strength and excellent heat resistance, this Mold Making Silicone offers great fluidity, strong urethane resin tolerance and reusable performance, with flexible packaging and a 12-month shelf life to fit global B2B furniture manufacturing needs.
Product Overview
This is a two-component room temperature vulcanizing (RTV) liquid silicone, part of our HY-E6 series, developed to solve the core pain points of urethane furniture molding. Unlike single-component silicone products, this RTV2 silicone only requires mixing the base material and curing agent before use, with no need for high-temperature curing equipment, which streamlines production and cuts overhead costs for furniture factories. It is formulated with enhanced durability and thermal conductivity, resisting deformation and chemical erosion during frequent casting, while perfectly replicating intricate carvings, curved profiles and delicate details of furniture components, suitable for small custom orders and large-scale batch production alike.

Product Features & Advantages
This RTV silicone has a translucent appearance that allows operators to clearly check mixing uniformity and pouring completeness, paired with outstanding fluidity that fills every fine detail of furniture designs without air bubbles or gaps. It features exceptional tear strength and long-lasting durability, preventing tears and wear during repeated demolding, which greatly extends mold service life and reduces replacement expenses. With zero shrinkage, it ensures consistent size and shape accuracy of finished urethane parts, while its upgraded heat and chemical resistance protects the mold from urethane corrosion, maintaining stable performance in continuous production runs.
How to Use the Product
Step 1: Prepare the furniture master pattern, clean the surface thoroughly to remove dust, grease and impurities, and dry it completely to ensure smooth mold release and a high-quality mold surface. Step 2: Select the suitable curing type (addition or condensation), weigh the base silicone and curing agent accurately according to the specified ratio, then stir slowly and evenly to avoid trapping excess air bubbles. Step 3: Conduct vacuum defoaming for 2-3 minutes to remove trapped air, which is essential for making smooth, defect-free molds. Step 4: Pour or brush the defoamed silicone evenly over the master pattern, covering all edges, corners and fine details fully. Step 5: Let the silicone cure completely at room temperature, demold gently once fully hardened, and the mold is ready for urethane, concrete or gypsum casting.
Application Scenarios
This liquid silicone is mainly used to produce molds for urethane furniture components, including decorative panels, carved trims, custom furniture parts and architectural furniture details. It also has a wide range of extended applications, such as product prototyping, architectural restoration, art sculpting, wax casting, concrete/GRC casting, gypsum decoration, resin crafts, tire molding, ceramic mold making, candle production, low melting alloy casting and general plastic casting. For furniture manufacturers, it improves production efficiency, ensures stable product quality, reproduces complex details perfectly, and lowers overall costs through long-lasting, reusable molds.
Certifications and Compliance
Our RTV silicone for urethane furniture molds complies with ISO 9001 quality management system and CE certification standards. It is non-toxic, odorless and environmentally friendly, meeting international industrial molding material safety requirements. Classified as a non-hazardous product, it fully follows global chemical import, export and transportation regulations, making it a reliable choice for furniture and decorative manufacturing enterprises worldwide.
Customization Options
We support flexible switching between addition curing silicone and condensation curing silicone to match different production processes. We can customize product hardness, fluidity and curing speed to fit different sizes, complexity levels and pattern details of furniture molds. We offer flexible packaging from small 1kg sample drums for testing to large 200kg bulk drums for mass production, and can optimize the formula for stronger urethane resistance to meet long-term, high-frequency casting needs.
Production Process & Brand Strength
We use high-purity Silicone raw materials and precise blending technology for the HY-E6 series, with strict quality inspection for each batch, focusing on key indicators like tear strength, shrinkage rate, heat resistance and resin compatibility. Our complete quality control system ensures stable and consistent performance across all batches. Our professional technical team provides targeted operation guidance, helping customers avoid common mistakes and maximize the service life of each mold.
