Aeropace Sealants

PPG Aerospace-PRC-Desoto. Global leadership in aerospace sealants and service. 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 elastomeric 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 in virtually every aircraft in the world. The tradition of leadership continues with innovative new sealants based on our advanced Permapol polymers. These sealants are lighter in weight, withstand higher temperatures, cure faster, and are easier to apply. Supported by a global network of Application Support Centers, each staffed by technical support specialists who can quickly provide needed service and information, PPG Aerospace-PRC-Desoto continues to establish higher standards for product and service excellence.
