Epoxy Potting Compound TEP‑004
Product Overview
TONMAX TEP‑004 is a general‑purpose two‑part AB epoxy potting compound that can be cured at room temperature or with heating. After curing, it forms a smooth, glossy and high‑hardness solid with outstanding electrical insulation performance. It is suitable for insulation and moisture‑proof potting of transformers and diverse electronic parts, and can also be used for confidential shielding encapsulation.
Main Applications
Insulation and moisture‑proof potting for various power transformers and instrument transformers
Encapsulation protection for inductors, coils and other electronic components
Confidential shielding encapsulation for proprietary electronic assemblies
Potting protection for electronic modules requiring high dielectric strength
Insulation sealing for industrial electronic control units
Core Advantages
✅ Cured surface is smooth and glossy with good appearance
✅ High Shore‑D hardness, excellent mechanical strength
✅ Superior insulation performance with high breakdown voltage
✅ Two‑component 5:1 mixing ratio, support room‑temperature or heating curing process
✅ High volume & surface resistivity for reliable electronic isolation
✅ Good heat‑distortion resistance, stable mechanical property under moderate temperature
Storage Note: Store indoors at 10‑35℃ with humidity below 70%, keep sealed and avoid direct sunlight. Recommended shelf‑life is less than 6 months.
