HONG YE SILICONE Liquid Tank Filter Silicone is a premium 1:1 two-component RTV 2 Silicone Rubber , engineered for high-efficiency sealing and bonding in industrial scenarios. With excellent high-temperature resistance (-40℃ to 200℃), strong adhesion to metals/plastics, and eco-friendly properties, it’s ideal for liquid tank air filters, LCD manufacturing, and high-temp equipment. Backed by ISO9001/CE certifications and 20+ years of expertise in Silicone raw materials and Electronic Potting Compound, it ensures reliable performance and global compliance for B2B buyers.
Product Overview
Also known as Jelly Silicone Gel or Liquid Tank Sealant , this product consists of transparent Part A and blue Part B (color customizable). As a core industrial offering complementing our Filter Potting Silicone and RTV Silicone Gel for Tank lines, it cures into a flexible, high-toughness elastomer. Non-toxic, no by-products during curing, and compatible with aluminum, galvanized steel, PC, PP, and ABS, it’s the preferred choice for air filter manufacturers and precision electronic component protection worldwide.
Technical Specifications

Product Features & Advantages
Superior Sealing & Durability: Cures to form an elastic seal that absorbs thermal expansion stress without cracking, maintaining long-term airtightness (surpassing ordinary Liquid Tank Adhesive ).
Broad Material Compatibility: Bonds seamlessly with metals and plastics—no extra primers needed (reducing production steps and costs).
Efficient Application: Low viscosity enables fast, uniform pouring; dual curing options fit flexible production rhythms (boosting efficiency by 30% vs. standard Industrial mold silicone rubber). Eco-Safe & Stable: Complies with global environmental standards, non-toxic and odorless; excellent weather and corrosion resistance (extending product lifespan).
Cost-Effective: One-time curing with no waste, reusable raw material (re-stirring after stratification) minimizes operational costs.
How to Use
Stir Part A and B separately in their containers to eliminate stratification (critical for consistent performance).
Mix A:B = 1:1 (weight), stirring thoroughly for 2-3 minutes to ensure uniform blending.
Degas at 0.08MPa for 3 minutes to remove air bubbles (avoids sealing defects).
Pour directly into liquid tank filter aluminum grooves or target areas, ensuring full coverage.
Cure at room temperature (8 hours) or heat (80-100℃, 20 minutes) — recommended for winter production to shorten curing time.
Application Scenarios
Air Filtration: Sealing for liquid tank high-efficiency air filters and high-temp air filter units (critical for cleanrooms and HVAC systems).
Electronics: LCD/optical electronic sealing, precision component moisture-proofing, power module potting (paired with our electronic Potting Compound for enhanced protection).
High-Temp Equipment: Bonding/sealing for industrial ovens, induction cookers, and high-temperature pipelines.
Value for Buyers: Reduces defect rates, ensures compliance with industry standards, and supports efficient mass production.
Certifications & Compliance
Customization Options
Offers color customization (blue, transparent, or brand-specific hues), viscosity adjustment for complex pouring needs, and packaging customization (20KG/200KG barrels) for bulk orders. Formula tweaks for extreme temperature resistance are also available.
Production Process
Undergoes high-purity raw material selection → automated precision mixing → pre-production sample testing (adhesion, curing speed) → batch curing inspection → final shipment inspection. 20 advanced production lines (same as Pad Printing Silicone line) guarantee consistent quality across batches.
FAQ
Q1: What substances will affect curing?
Q2: Can it be used for outdoor applications?
A: Yes, excellent weather resistance ensures stable performance in harsh environments.
Q3: What’s the MOQ for custom colors?
A: 20KG (A+B set) for small batches, 200KG for bulk orders.
