GPS (Graphite Plate Sealant) 996T

Hernon GPS (Graphite Plate Sealant) 996T is a single component electron beam or heat cure impregnation sealant formulated especially for Bipolar plates in fuel cells. GPS 996T outperforms all impregnation sealants currently used in the industry for this purpose. Low surface tension of the sealant allows it to penetrate the smallest pores in graphite plates and offers excellent washability. High Tg and hardness help graphite plates to keep their performance and shape at high temperatures as well as increase the life of the plates. UV traceability of the sealant helps for quick inspection of the plates. Product Benefits • Single component • Excellent Washability, no need for washing surfactant. • High Hardness. • Excellent water and glycol resistance • High heat resistance • Bonds to graphite • Overcomes sulfide contamination in graphite. • Can be cured with electron beams or heat.
