PRC? and Pro-Seal? Aerospace Sealants

Haas Group International offers a wide range of PRC- and Pro-Seal- brand aerospace sealants. These include elastomeric products that resist deterioration from jet fuel. They have become the industry standard for sealing fuel tanks in virtually every aircraft in the world.

This leading position is reinforced through the development of sealants based on PRC-DeSoto's advanced Permapol? polymer technology. Lighter in weight, these sealants withstand higher temperatures, cure faster, do not require primers, and are easier to repair.
