LENGTHENING LIFESPANS I
How corrosion resistance has shifted from protection to prevention (-76°F
n the ongoing battle against corrosion and asset integrity, the desire to extend asset lifespan has shifted towards prevention rather
than mere protection. Traditional sealants and sealing method complexity and volatility often lead to disputes over responsibility and quality compromises. However, the growth in use and proven success of polyisobutene (PIB) sealants, are eff icient and safer to apply while reducing maintenance needs over an asset’s lifetime.
A GAME-CHANGER PIB-based sealants off er signifi cant advantages over conventional sealing systems. These PIB-based sealants remain in a viscous state throughout their lifetime, maintaining fl uidity even at temperatures below -60°C

1. Provide immediate and constant surface adhesion, creating a self- adhering effect
2. Form an instant barrier against oxygen and water
3. Adapt to thermal expansions, contractions, and asset movements
4. Penetrate surface pores effectively, ensuring lasting encapsulation from the environment
One of the most signifi cant benefi ts of PIB-based sealants is their simplifi ed application process as well as the following:
1. Minimal surface preparation/ cleanliness: Only removing loose existing debris, oil, or grease from the substrate.
2. Reduced inspection points: Fewer steps are required to achieve necessary surface cleanliness and preparation for sealing.
3. Simplifi ed equipment: Cold applied by hand and hand tools like scissors, without the need for harmful primers.
4. No dry times or shutdown requirements: Application can be done without interrupting operations, and service can start on new construction immediately after application.
