FAQ
Q1: What is the core advantage of this potting compound?
A: It delivers professional frost crack resistant encapsulation and subzero cycle module potting, providing
long-term cold climate durability protection for electronics in extreme temperature alternating environments.
Q2: Will repeated freezing and thawing damage the encapsulation layer?
A: No. Its flexible low-temperature formula resists thermal and cold cycling stress, maintaining intact structure
and protective performance after thousands of freeze-thaw cycles.
Q3: Does colloidal stratification affect low-temperature resistance?
A: Stratification is a normal storage phenomenon. Stir evenly before use, and its freeze-thaw tolerance and
overall protection performance remain unchanged.
