For a better bond and a seal that sticks, order a bottle of PPG Aerospace® PR-188 Adhesion Promoter from SkyGeek. The single-component promoter is suitable for use with PRC and Pro-Seal brand sealants, enhancing the adhesion of both polysulfide and Permapol® polythioether-based sealants applied to standard aerospace substrates. The promoter is a liquid and goes on easily, spreading over the surface and helping to ensure complete bonding. PPG Aerospace® PR-188 Adhesion Promoter has a vibrant blue color, so it's easy to see where it has been applied.
