Polyurethane Castable
Hot cure 90oC |
49SF 45SF
49SF + B |
|
45SF or 49SF is the standard for DUOTHANE®, Vulkollan®, Adiprene®,
Vibrathane etc.
Cilbond 49SF+B gives the ultimate in water and heat
resistance |
|

|
For bonding Quasi systems at 50-80oC with 49SF a prebake is
required.
For improved environmental resistance use 49SF + B or 41 +
B |
|
Polyurethane Castable
Cold Cure 20oC,
