molybdates alkali metal molybdates various antifoaming agents and dyes if desired for example the invention will be further illustrated by the following examples which are not intended to limit the invention but rather to illuminate it additionally stabilizers may be added such as for example polysiloxane stabilizers to prevent alkali metal silicate caused gellation problems a blend of ethylene glycol sodium sebacate 2 4 wt sodium metasilicate pentahydrate 0 2 wt and tolyltriazole 0 2 wt was prepared and tested in the astm d 4340 aluminum heat rejecting surface test with passing results results are presented in table i below a blend of ethylene glycol sodium sebacate 3 0 wt sodium metasilicate pentahydrate 0 1 wt and tolyltriazole 0 2 wt was prepared and tested in the corrosion tests as example 1 this blend failed the astm d 4340 aluminum heat rejecting surface test as shown in table i below a blend of ethylene glycol sodium sebacate 2 7 wt and tolyltriazole 0 2 wt without a silicate was prepared and tested in the corrosion test as example 1 the results are presented in table i other examples were conducted using the procedure outlined above except for the changes made as noted in examples 4 through 10 of table i table i______________________________________effect of various corrosion inhibitor mixturesin astm.
