Product Features
1.Excellent Flowability
Low viscosity enables rapid wetting of intricate core geometries.
2.Shrinkage-Free Cure
Maintains dimensional stability during curing, preventing internal stress and delamination.
3.Long-Lasting Clarity
Resists UV and yellowing to stay clear and glossy over extended use.
Applications
1. Laminated Silicon Steel Cores
Insulates and bonds laminations to prevent mechanical vibration during operation.
2. Dry-Type Transformer Cores
Forms a clear protective layer for visual inspection without compromising heat dissipation.
3. Precision Electromagnetic Components
Delivers reliable encapsulation where optical clarity and structural strength are required.
Processing Instructions
Mixing
Mix main agent and curing agent at a 2:1 mass ratio until homogeneous.
Degassing
If needed, degas under vacuum for 5–10 minutes to eliminate entrapped air.
Application
Apply by brushing, dipping, or spraying to ensure complete and uniform coverage.
Curing
Surface dry in ~4 hours at 25°C; fully cured in 24 hours at room temperature.
Customization Options
We offer flexible customization to meet diverse application needs:
Viscosity fine-tuning (for different coating processes)
Cure speed optimization (standard or fast-cure versions)
Packaging size options (standard drums or trial batches)
Enhanced weatherability (improved yellowing resistance)
