RTV31, RTV60 and RTV88 silicone rubber compounds are high temperature two-part silicone elastomers. They are supplied ready-to-use with a base compound and DBT (dibutyl tin dilaurate) as the standard curing agent. DBT is suitable for most applications, however other catalysts are available to facilitate deep section cure, faster cure and automated mixing.
RTV31, RTV60 and RTV88 silicone rubber compounds differ primarily in viscosity in the uncured state. Momentive - RTV31 Key Features and Benefits
Variable work times and cure rates by adjusting the amount and type of curing agent
Room temperature cure
Composition free of solvents and solvent odor
Excellent adhesion capabilities with primer
Excellent release properties
Retention of elastomeric properties at temperatures from -54°C (-65°F) up to 260°C (500°F) continuously, and up to 316°C (600°F) for short periods of time
It's the standard pilot log for a reason. Many different flight time categories with just enough space for remarks. As a helicopter pilot, it would be nice if the endorsements section wasn't fixed-wing focused; but I get that there are a lot fewer helicopter pilots out there, so I won't dock any stars for that. This is my third ASA-SP-57 logbook at this point, and I intend to keep getting more of them in the future.
This is nearly identical to my first pilot logbook, but with a new smooth matte black cover. This logbook checks all the boxes from student pilot through Commercial. It might just be the only logbook you’ll ever need. Fly safe!
