HDPU Mechanical Protection Infill

Aegion Coating Services’ Gatorback system (P450-8.0 IS) is a proprietary system formulated without the use of aromatic hydrocarbons, commonly used in competitive systems. The elimination of hydrocarbons in the P450 – 80 IS system allows for a safer and environmentally friendly system and is typically applied over each girth weld area of offshore pipelines with concrete weight coating.

• Removable mold with outer reinforcing wrap does not peel off
• Porous outer wrap allows quick saturation of the foam and does not shield cathodic protection
• Foam is specially designed for immersion service and does not contain CFC or HCFC blowing agents
• PSI-P450-80IS foam is formulated without hydrocarbon solvents
• Two-component system mixed on a 1:1 ratio by volume
• Readily pumped by standard plural component piston pumps
• Foam quickly fills mold to achieve the compressive strengths necessary for stinger loads
• Chemical components stay in solution and do not separate
• Each shot results in a consistent joint
• Nonflammable foam components
• Health and safety standards are easily met
• Tough outer surface resists damage during pipeline lowering and subsea activities
• Simple, quick installation for short cycle times
