Product Features & Advantages
1. Ultra-Low Viscosity & High Flowability: Viscosity as low as 500 mPa·s, excellent fluidity, can freely flow into tiny gaps (≥0.1mm) and complex mold structures, solving the problem of traditional foaming materials’ high viscosity and difficulty in filling complex molds.
2. Full Filling Without Dead Corners: Good flowability ensures full filling of complex molds and tiny gaps, no air pockets, no missing parts, ensuring the integrity and precision of molded products, reducing molding defects.
3. Low Viscosity & Performance Balance: While maintaining ultra-low viscosity, it retains good elasticity and dimensional stability, no deformation after curing, ensuring the performance of complex-shaped products is not affected by low viscosity.
4. Complex Molding Compatibility: Compatible with HONG YE SILICONE’s high-precision mold silicone and rapid prototyping silicone, forming a complete complex molding solution, enabling one-stop procurement for complex part buyers.
5. Easy Flow Operation: 1:1 simple mixing ratio, low viscosity ensures easy mixing and pouring, no need for high-pressure pouring equipment, reducing production costs and improving molding efficiency.
How to Use
1. Take Part A and Part B according to 1:1 weight ratio, stir separately to eliminate sediment, ensure no impurities (avoid affecting flowability and filling effect).
2. Mix and stir thoroughly for 2 minutes until homogeneous, vacuum degas to remove air bubbles (ensure full filling and pore uniformity).
3. Pour the low-viscosity mixture into complex molds or tiny gaps (paired with high-precision mold silicone), relying on its own flowability to fill completely, no need for additional pressure.
4. After full curing, demold gently, the product is intact, no missing parts, ready for direct use without secondary trimming.
Application Scenarios
Focus on complex molding scenarios: Complex-shaped electronic components (paired with Electronic Potting Compound), tiny precision parts molding (paired with high-precision mold silicone), intricate robot components (paired with robot silicone), rapid prototyping of complex structures (paired with rapid prototyping silicone), and tiny gap filling (paired with Liquid Tank Silicone). It helps complex part buyers improve molding efficiency and product integrity.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, ultra-low viscosity and high flowability, meeting the complex molding procurement requirements of B2B buyers in various industries, facilitating export to global precision molding markets.
Customization Options
Customizable viscosity (300-2000 mPa·s adjustable), flow rate, foaming ratio and curing time, adapting to different complex mold sizes and gap requirements, helping buyers optimize filling effect and molding efficiency.
Production Process
Low-viscosity-oriented production process: High-purity low-viscosity Silicone raw materials → formula optimization (reduce viscosity while maintaining performance) → precision mixing → viscosity and flowability test → standardized curing → filling effect inspection → packaging. Strict viscosity control ensures excellent flowability of each batch.
