Cure promoter compositions and methods for the same

A cure promoter composition, comprising:

• disulfiram;
• pentaerythritol tetrakis (3-mercaptopropionate);
• an accelerator comprising sulfur chloride;
• one or more organic solvents comprising a ketone;
• a catalyst comprising 1-methylimidazole;
• one or more reactive silanes;
• one or more reactive organometallics;
• one or more gelling agents;
• a catalyst, comprising an amidine;
• and
• an aqueous component;
• wherein the cure promoter composition has a shear viscosity at 25° C. of from 0.01 to 10 Pa·s;
• and, when brushed onto an uncured polysulfide sealant, produces a tack-free surface in less than 60 minutes at 25° C.

A method for applying a cure promoter composition, comprising:

• contacting one or more organic solvents comprising a ketone, an accelerator comprising disulfiram, a compatibilizing carrier, comprising pentaerythritol tetrakis (3-mercaptopropionate), one or more optional reactive silanes, one or more optional organometallics, and a catalyst comprising a diazole, comprising 1-methylimidazole, with one another to prepare a cure promoter composition having a shear viscosity at 25° C. of from 0.01 to 10 Pa·s;
• homogenizing the cure promoter composition;
• applying a sealant, resin, paint layer, or combinations thereof onto a substrate;
• applying the cure promoter composition to a surface of the sealant, resin, paint layer, or combinations thereof;
• evaporating the one or more organic solvents from the cure promoter composition;
• and
• pausing to allow the cure promoter time to react;
• wherein the composition, when brushed onto an uncured polysulfide sealant, produces a tack-free surface in less than 60 minutes at 25° C.
