It supports room-temperature storage and rapid heat curing, has no shrinkage during curing and detachable performance, and is compatible with automated production lines. As a core product matching our liquid silicone, RTV 2 Silicone Rubber, Industrial mold silicone rubber, Pad Printing Silicone and Silicone Encapsulant, it is an ideal choice for potting complex electronic parts, with customizable viscosity to meet diverse industrial application needs.
Product Overview
Our Liquid Potting Silicone is a professional organic silicone potting material engineered for bonding, sealing, potting and coating protection of electronic components, a key part of HONG YE SILICONE’s full silicone product matrix. Uncured it is a free-flowing liquid with adjustable viscosity based on application needs, able to pour into tiny gaps of complex electronic parts and realize self-defoaming for a smooth potting effect. Fully cured it forms a stable protective layer with comprehensive performance, far superior to ordinary epoxy and polyurethane potting adhesives in aging and temperature resistance, and its detachable feature allows easy repair of sealed components, perfectly matching the mass production and maintenance needs of electronic manufacturing enterprises.
Product Features & Advantages
1. UL94-HB flame retardancy: Achieves standard flame retardant performance, effectively reducing fire risks of electronic products and improving the safety of equipment in use.
2. Easy potting for complex parts: Low viscosity, good fluidity and self-defoaming property enable smooth pouring into fine gaps of electronic components, no need for extra defoaming for most scenarios.
3. Detachable & repairable: Sealed components can be taken out for repair and replacement, and patching with this potting silicone leaves no traces, greatly reducing after-sales maintenance costs.
4. Flexible curing mode: Mixed glue has a long pot life at room temperature, and can be rapidly cured under heating, suitable for both manual operation and automated production line use, improving production efficiency.
5. Zero shrinkage & stable protection: No shrinkage during curing, forming a tight and fit protective layer with excellent waterproof, moisture-proof and anti-aging performance, ensuring long-term stable protection of electronic components.
6. Multi-performance integration: Retains excellent silicone properties such as acid and alkali resistance, atmospheric aging resistance, insulation, pressure resistance, moisture and shock proofing, adapting to various harsh working environments.
Technical Specifications
This liquid potting silicone is a two-component organic silicone material with adjustable viscosity customized according to customer needs, supporting room temperature and heating curing modes. It reaches UL94-HB flame retardant grade, has no shrinkage during the entire curing process, and the cured product maintains stable physical and chemical properties in a wide temperature range. The mixed glue has a long open time at room temperature, and the curing speed can be flexibly adjusted by heating temperature, matching different production line beat requirements. All performance parameters can be optimized and customized according to the specific application scenarios of customers.
How to Use
1. Preparation: Fully stir both components of the silicone to ensure uniform mixing of internal fillers, and shake well to avoid stratification, which is the key to stable curing performance.
2. Mixing: Blend the two components according to the specified weight ratio, stir evenly and let stand for a short time to eliminate air bubbles generated during mixing (self-defoaming for most scenarios).
3. Potting: Pour the mixed glue directly into the electronic component mold or the part to be potted, relying on fluidity to fill all gaps naturally.
4. Curing: Choose room temperature curing for small-batch operation, or heat curing for automated production lines to accelerate the curing process; wait for full curing to realize the complete protective performance of the product.
Application Scenarios
Widely used for bonding, sealing, potting and coating protection of various electronic components, including circuit boards, power supplies, sensors, LED modules, electronic ballasts and small household appliance control panels. It is the preferred potting material for electronic manufacturing, automotive electronics, industrial control, consumer electronics and other industries, effectively protecting core components from moisture, dust, corrosion and mechanical impact, and improving the service life and market competitiveness of electronic products.

FAQ
Q1: What substances should be avoided during use to prevent uncuring?
A1: Avoid contact with organotin compounds, sulfur and sulfides, amine compounds and their containing materials, as well as organotin-containing silicone rubber, which will cause the product to fail to cure normally.
Q2: How to store the unused liquid potting silicone?
A2: The two components should be sealed and stored separately in a cool and dry place; mixed glue should be used up at one time to avoid material waste caused by gradual curing.
Q3: What if the silicone is layered after long-term storage?
A3: This is a normal physical phenomenon of silicone materials; just fully stir the material before use, and the performance will not be affected at all.
Q4: Is the product harmful to the human body and how to deal with accidental contact?
A4: It is a non-hazardous material, but avoid contact with mouth and eyes; rinse the affected area with clean water immediately if accidental contact occurs, and no special treatment is needed for mild contact.
Q5: Can this product replace epoxy and polyurethane potting adhesives?
A5: Yes, it has better aging, temperature and moisture resistance than ordinary epoxy and polyurethane potting adhesives, and has detachable advantages, which is a more ideal potting material for electronic components with long service life requirements.
