Fasto TG100 – High-Performance Thermally Conductive Silicone Grease

Q: What is Fasto SP70 used for?

Fasto SP70 is a two-component silicone potting compound specially designed for potting solar PV junction boxes. It protects electrical connections from moisture, dust, UV radiation, thermal cycling, and environmental exposure.

Q: Why is potting required in solar junction boxes?

Potting creates a protective barrier around electrical components inside the junction box, preventing moisture ingress, corrosion, electrical leakage, and mechanical damage while improving long-term reliability.

Q: How can I select the right potting compound for my solar application?

The ideal potting compound should provide UV resistance, electrical insulation, moisture protection, thermal stability, and long-term outdoor durability. Fasto SP70 is specifically engineered to meet these requirements for solar junction box applications.

Q: What industries commonly use Fasto SP70?

Fasto SP70 is primarily used in: Solar PV module manufacturing Renewable energy equipment Electrical and electronic assemblies Outdoor power systems

Q: 8. What are the key benefits of using Fasto SP70?

Key benefits include: Excellent weather resistance Superior UV stability Strong moisture protection Electrical insulation Long-term outdoor durability Reliable performance in harsh environments Protection against vibration and mechanical stress

Fasto TG100 is a one-part, non-curing, high-performance silicone-based thermal grease designed to ensure efficient heat transfer between heat-generating components and heat-dissipating surfaces. It is specially formulated to fill microscopic air gaps, reducing thermal resistance and improving heat dissipation in electronic, electrical, and LED assemblies.

Surface Preparation

Ensure contact surfaces are clean, dry, and free from rust, scale, dust, grease, oil, release agents, or any other contaminants.
Clean surfaces using a suitable Fasto cleaner for optimal thermal contact and performance.

Application Method

Apply Fasto TG100 evenly using a spatula or suitable applicator.
Spread the paste uniformly to eliminate trapped air between the heat-emitting surface and the heat-radiating surface.
Apply sufficient quantity to ensure complete surface contact, then wipe off excess material.
Avoid excessive application, as it may reduce thermal efficiency.

Application Conditions

Application temperature range: 5°C to 40°C
Optimum application temperature: 15°C to 25°C
