The role of IOTA-792 in polysulfide sealants

Traditional polysulfide sealants have insufficient adhesion to metal and glass, often requiring a separate primer.
The introduction of IOTA-792 can radically change this situation:
Addition levels of just 0.5–1.0 wt% can significantly improve adhesion;
The bond failure mode shifts from adhesive failure to cohesive failure, demonstrating a strong interfacial bond;
The elimination of the primer step reduces application cost and complexity.
As a result, IOTA-792 can help sealants achieve a more durable, reliable bond in applications requiring long-term, durable sealing, such as aviation, construction, and transportation.
