Hydrogen-Resistant Sealing & Insulating Potting for H2 Equipment

Low-hydrogen-permeation sealants and insulating potting for electrolysers, hydrogen tanks and fuel cells across wide temperature ranges.

Hydrogen molecules are tiny and highly permeating — a major sealing challenge.

Guangnian develops low-permeation PU/epoxy systems for long-term sealing and electrical insulation under thermal cycling and high-pressure hydrogen service.
