PPG PR-1422 Discontinued due to REACH

Due to REACH regulations, we are no longer able to distribute PPG PR-1422 Fuel Tank Sealant.

"In 2006, the European Union passed a piece of legislation known as REACH (Registration, Evaluation, Authorization, and restriction of Chemical substances) with the intent to protect human health and the environment. In accordance with REACH, PPG Aerospace will cease manufacture of PR-1422 in the European Union in 3rd quarter of 2013. It is anticipated that supply to customers inside the European Union will end during the 4th quarter of 2013. Manufacture of PR-1422 will continue in the United States and availability of the product to the Americas, Africa, the Middle East, and Asia/Pacific will be unaffected."

Recommended Substitutes

The replacement product for all grades of PR-1422 is PR-1440, which has a 50-year track record of success in the aerospace industry. For most customers, this will enable inventory reduction as it already has several applications across the OEM and MRO market.

Like for like - PR-1440

PPG PR-1440 is an aircraft integral fuel tank sealant which has a service temperature range from -54°C (-65°F) to 121°C (250°F), with intermittent excursions up to 135°C (275°F).

PR-1440 Class A is designed for brush sealing of fasteners in fuel tanks and other aircraft fuselage sealing applications.

PR-1440 Class B is designed for fillet sealing of fuel tanks and other aircraft fuselage sealing applications.

Within both classes, the cured sealant maintains excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gas.

Lightweight - PR-1776MB

PPG PR-1776M Class B is recommended for Boeing and Bombardier aircraft (there are currently no lightweight A or C grades in use at Boeing and PR-1440 that can be used). PR-1776M Class B is a low-density, high-temperature aircraft integral fuel tank sealant that has a service temperature range from -54°C (-65°F) to 121°C (250°F), with very limited excursions up to 182°C (360°F).

This material is designed for fillet sealing of fuel tanks and other aircraft fuselage sealing applications. It offers as much as a twenty per cent weight saving per unit volume, compared to traditional sealants used for these purposes. The cured sealant maintains excellent elastomeric properties after prolonged exposure to aircraft fuels both jet fuel and aviation gas, and will resist limited contact to phosphate ester-based hydraulic fluids.

Airbus Aircraft - PR-1782

PPG PR-1782 is a low density, aircraft fuel tank and general purpose sealant which has a service temperature range from -54°C to 121°C (-65°F to 250°F).

PR-1782 Class A is designed for brush sealing of fasteners in fuel tanks and other aircraft fuselage sealing applications.

PR-1782 Class B is designed for fillet sealing and other aircraft fuselage sealing applications.

PR-1782 Class C is designed for fay surface sealing applications.

All classes offer as much as a thirty per cent weight saving per unit volume, compared to traditional sealants used for these purposes. The cured sealant maintains excellent elastomeric properties after prolonged exposure to aircraft fuels both jet fuel and aviation gas, and will resist limited contact to phosphate ester based hydraulic fluids.
