Two-Component Silicone Sealant GW8230 (15#) A/B – Thermally Conductive Sealing Compound
Basic Information
Product: GW8230 (15#) A/B
Type: Two-component silicone sealant
Characteristics: Thermally conductive, pourable, room-temperature curable
Overview
GW8230 (15#) A/B is a two-component, thermally conductive silicone sealing compound designed for potting, encapsulation, and sealing of electronic and electrical components. After mixing the two parts (A and B), the material exhibits good flowability, allowing it to fill complex cavities and conform to components. The working time (pot life) can be adjusted by varying the temperature, providing flexibility in processing. The material cures at room temperature, simplifying application without the need for heating equipment.
Key Properties
Thermally conductive – facilitates heat dissipation from power components and other heat-generating parts.
Good flowability – ensures complete filling and coverage of intricate surfaces.
Adjustable pot life – can be extended or shortened by controlling temperature, accommodating different processing times.
Room-temperature curing – no external heating required, reducing energy costs and simplifying operations.
Good adhesion – bonds well to metals, plastics, ceramics, and glass.
Excellent electrical insulation – maintains dielectric strength for electronic applications.
Stable performance – resistant to moisture, dust, and mild chemicals.
Wide operating temperature range – suitable for demanding environments.
Applications
Sealing of heat-dissipating components such as power modules, LEDs, and heat sinks.
Potting of transformers, coils, and sensors.
Encapsulation of electronic assemblies requiring thermal management.
Protection of components exposed to temperature fluctuations and mechanical stress.
Suitable for use in automotive electronics, industrial controls, and consumer electronics.
Curing Conditions
Curing time depends on temperature – typically 24 hours at 25°C, but can be accelerated by applying mild heat or extended by cooling.
Optimal curing conditions should be validated for specific applications.
Handling and Storage
Store both components (A and B) in a cool, dry place, away from direct sunlight and moisture.
Keep containers tightly sealed after use to prevent contamination.
Shelf life: typically 6–12 months under recommended storage conditions.
Use appropriate personal protective equipment (gloves, safety goggles) when handling uncured material.
Avoid contact with amines, sulfides, and unsaturated hydrocarbons which may inhibit curing.
Packaging
Available in various container sizes (e.g., 100 g, 500 g, 1 kg, 5 kg kits) and custom packaging upon request.
Quality Assurance
Each batch is tested for viscosity, thermal conductivity, curing time, and adhesion to ensure consistent and reliable performance.
