FAQ
Q1: What is the core advantage of this potting silicone?
A: It is an extreme temperature cycling encapsulation and rapid change module potting compound, providing
durable cracking prevention circuit protection for temperature-fluctuating electronic devices.
Q2: Can it work stably in long-term temperature cycling environments?
A: Yes. The high-tough formula absorbs thermal stress effectively, resisting aging and cracking caused by
repeated thermal shock.
Q3: Does colloidal stratification affect thermal shock resistance?
A: Stratification is a normal storage phenomenon. Stir evenly before use, and the core thermal shock
resistant performance remains unchanged.
