Traditionally, Aerospace Sealants have been provided in two part kits (base and accelerator) which are mixed just before usage. Pre-mixed and frozen sealants are mixed, packaged and then quick frozen at one of our PPG Aerospace Application Support Centers (ASC). They are then shipped to the customer on a just-in-time basis. Afterwards, the PMF sealants are simply thawed at the work station and are ready to be used.

Pre-mixed and frozen sealants offers a variety of benefits for the customer that are not available in other traditional packaging options. These benefits include reduced waste, improved quality, increased efficiency, and costs savings.


Why Consider PRC® Pre-mixed and Frozen Sealants?

Cost Savings

  • Elimination of shop mixing saves time

  • Numerous PMF package size options (the right size for the right job), thus eliminating waste significantly-more sealant gets the part instead of on the trash.

  • Just in time delivery means the product is always fresh, eliminating waste due to shelf life expiration.

Improved Quality

  • Air: Reduces air in the sealant due to improper mixing.

  • Mix: Ensures the product is thoroughly and properly mixed, maintaining application and performance properties

  • Cure & Hardness: Tests are run to verify that each run/mix meets its specifications

Increased Efficiency

  • Customer’s freezer stocked weekly by PPG (POU Programs)

  • Eliminates potentially costly rework due to shop mix errors

  • Eliminates lost production time to mixing material

  • Reduces concern for expired material and stock outs

  • Materials packaged for maximum economy and efficiency (Cartridges 1oz, 3oz, 6oz, 25gm and 50gm)

Environmental Standards

  • Reduced employee exposure to material

  • All materials packaged in convenient, stable, ready to use, safe containers


Technology & Packaging

The majority of PRC® and Pro-Seal™ aerospace sealants are available in a variety of pre-mixed frozen packaging. Immediately after mix the products are quick frozen. Secondary quality conformance testing is run on each run to assure it completes conformance. Upon final approval the Pre-Mixed Frozen products are packaged in a specially designed shipping container that maintains the correct storage temperature during shipping. The material is shipped to the end-user who needs only to thaw the cartridges and apply the sealant.
