Features & Benefits
Thermal rupture resistance allows it to retain pressure of 10 psi with negligible deformation.
Low temperature flexibility at -65°F (-54°C) ensures no cracking, checking, or loss of adhesion.
Corrosion resistance prevents corrosion, adhesion loss, softening, or blistering.
Flexibility is maintained with no cracks after bending 180 degrees over a 0.125 inch (3.18 mm) mandrel.
Repairability to itself is excellent for both freshly cured and fuel-aged or abraded fillets.
Resistance to other fluids includes excellent performance against water, alcohols, petroleum-based and synthetic lubricating oils, and petroleum-based hydraulic fluids.
Fungus resistance ensures non-nutrient properties to prevent fungal growth.
