Shelf Life: 12 months

Product Description:

Insulcast LN 1-05 is a low-exotherm, non-cracking epoxy compound designed specifically for large potting and encapsulation applications. It maintains excellent electrical insulation properties across a wide temperature range and is formulated with advanced polymer and filler technology to minimize shrinkage and internal stresses. This makes it an ideal solution for thick-section castings and high-volume electronic potting applications.


Key Features:

✅ Low Exotherm Formula: Prevents excessive heat build-up, reducing internal stresses.
✅ Non-Cracking: Ensures structural integrity, even in large castings.
✅ Excellent Electrical Properties: Provides high dielectric strength and volume resistivity.
✅ Advanced Polymer and Filler Technology: Reduces shrinkage and enhances durability.
✅ Good Thermal Conductivity: Ensures effective heat dissipation in electronic applications.


Recommended Applications:

🔹 Large Potting Applications: Ideal for encapsulating sizable electronic components.
🔹 Encapsulation Processes: Protects sensitive electronics from environmental damage.
🔹 Transformer & Coil Potting: Provides insulation and structural stability.
🔹 Industrial Electronics: Used in control modules, power supplies, and high-voltage equipment.
