Abstract:

B-58 glazings are manufactured with a trans parent, high temperature silicone interlayer Type K laminated between two tempered glasses to prevent shattering if breakage occurs. At present, it is the only commerically available material that will withstand the high temperaturevnnvironment of the B-58 airplane. Nevertheless, it has the disadvantage of deteriorating in an environment of sunhgght, moisture and acidic gases. An approach to the problem was to satu rate cured Type K interlayer with a non-dele terious gas which will exclude subsequent entry of deleterious gases. This approach lead to another possible alternative, that of saturating the Type K interlayer with heat stable liquid amines which would react with acidic gases. Protection of Type K interlayer from deleterious acidic gases by preimpregnating it with non deleterious gases did not appear feasible. It appeared feasible to protect Type K interlayer from deleterious acidic gases byrreimpregnating it with liquid amino silanes. Author
