1.1 Form
This specification covers a permanently mastic fluorosilicone sealing compound in the form of a paste.
1.2 Application
This product has been used typically for sealing or resealing integral fuel tanks designed for groove-injection type sealing
for use from -65 to +360 °F (-54 to +182 °C), but usage is not limited to such applications.
1.3 Classification
Sealing compounds covered by this specification are classified as follows:
Class 1 - High viscosity, permanently mastic, fuel resistant, fluorosilicone paste compound suitable for sealing
applications with structural mismatch of 0.005 inch (0.13 mm) or less, normally contains glass bead filler
material.
Class 2 - Medium viscosity, permanently mastic, fuel resistant, fluorosilicone paste compound suitable for sealing
applications with structural mismatch of 0.005 inch (0.13 mm) or less, normally contains glass bead filler
material.
Class 3 - High viscosity, permanently mastic, fuel resistant, fluorosilicone paste compound suitable for sealing
applications with structural mismatch of 0.015 inch (0.38 mm) or less, normally contains cured fluorosilicone
rubber particles.
