For more than 50 years, PPG Aerospace – PRC-DeSoto has been a leader in the development of products fundamental to aerospace manufacturing, maintenance, and repair. That leadership is firmly established in the highly specialized field of aerospace sealants.

PRC® aerospace sealants were the first products capable of resisting deterioration from long-term exposure to jet fuel. Since then, sealants such as PR-1422  and Pro-Seal™ 890  have become acknowledged industry standards for sealing fuel tanks.

The PPG Semkit® and Tooling Options allow the application of the correct sealant in the right place, while maintaining production costs.

The Semkit® package assures accurate proportioning of the materials since the premeasured components are stored in different compartments within the cartridge.  Your materials can be packaged in Semkit® packages with capacities of 1 oz. (30cc) to 20 oz. (610cc).  Semi-automatic and fully automatic mixing equipment is also available.
