The stability of Neoprene cements containing metal oxides could be increased with about 10 parts of hydrated calcium silicate, (e.g., Sil-ene EF, PPG Industries) or terpene phenolic resin (e.g., Durez 12603, Occidental Chemical Co.). The presence of the former increased the cohesive strength of Neoprene about threefold, while the latter lowered its cohesive strength at elevated temperatures. 

Where adhesion is required, all sealants need an adhesion additive. For two-part building sealants, a selected phenolic resin (Methylon AP-108, General Electric) has been very satisfactory. A silane monomer is used for the one-part sealants. Aircraft sealants have used a selected phenolic resin which is more resistant to the jet fuels. A Durez resin, 10694 (Occidental Chemical Corporation) has been most satisfactory.
