Product Description

HONG YE SILICONE Liquid Tank Filter Silicone is a premium 1:1 two-component RTV 2 Silicone Rubber , engineered for industrial sealing and bonding. 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 sealing 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 product complementing our Filter Potting Silicone and RTV Silicone Gel for Tank lines, it cures into a flexible elastomer with superior sealing performance. Non-toxic, no by-products during curing, and compatible with aluminum, galvanized steel, PC, PP, ABS, it’s the first choice for air filter manufacturers and electronic component protection needs.

Technical Specifications

Type: RTV 2 Silicone Rubber

Mixing Ratio: A:B = 1:1 (by weight)

Viscosity: Low-flow (easy pouring)

Curing Condition: Room temperature (3-8 hours) or 80-100℃ (20 minutes)

Degassing Requirement: 0.08MPa for 3 minutes

Shelf Life: 1 year (sealed storage, avoid acids/alkalis)

Packaging: 20KG/200KG barrels (A/B components, non-hazardous shipping)

Key Performance: No oil bleeding, thermal stress resistance, broad material compatibility

Product Features & Advantages

Superior Sealing & Durability: Cures to form a high-toughness elastomer that absorbs thermal expansion stress without cracking, maintaining long-term airtightness (surpassing ordinary Industrial mold silicone rubber).

Broad Material Compatibility: Bonds seamlessly with metals and plastics—no extra primers needed (reducing production costs and steps).

Efficient Application: Low viscosity enables easy pouring; dual curing options fit different production rhythms (boosting efficiency by 30% vs. standard silicone).

Eco-Safe & Stable: No toxic emissions, compliant with global safety standards; excellent weather and corrosion resistance (extending product lifespan).

Cost-Effective: One-time curing with no waste, lower long-term operational costs vs. Liquid Tank Adhesive alternatives.

How to Use

Stir Part A and B separately in their containers to eliminate stratification.

Mix A:B = 1:1 (weight), stirring thoroughly for 2-3 minutes.

Degas at 0.08MPa for 3 minutes to remove air bubbles (avoids sealing defects).

Pour directly into liquid tank filter aluminum grooves, ensuring full coverage.

Cure at room temperature (8 hours) or heat (80-100℃, 20 minutes) (recommended for winter).

Application Scenarios

Air Filtration: Sealing for liquid tank high-efficiency air filters and high-temp air filter units.

Electronics: LCD/optical electronic sealing, precision component moisture-proofing, power module potting (paired with our electronic Potting Compound ).

High-Temp Equipment: Bonding/sealing for ovens, induction cookers, and industrial heaters.

Value: Reduces defect rates, ensures compliance, and supports efficient mass production.

Certifications & Compliance

Meets ISO9001 quality standards and CE safety regulations, consistent with our Medical Grade Body Silicone and Food grade mold silicone—ensuring smooth global market access.

Customization Options

Offers color customization (blue, transparent, or custom hues), viscosity adjustment for specific pouring needs, and packaging customization (20KG/200KG barrels) for bulk orders.

Production Process

Undergoes high-purity raw material selection → automated precision mixing → pre-production sample testing → batch curing inspection → final shipment inspection. 20 production lines (same as Pad Printing Silicone line) guarantee consistent quality.
