Abstract
This invention describes the use of blocked mercaptosilanes wherein the hydrogen atom of the mercaptan functionality has been substituted to manufacture coating, adhesive, sealant and elastomeric compositions. The blocked mercaptosilanes described are unique in that they allow the application of elastomers to substrates to proceed while remaining inert toward coupling to the catalyst. The coupling reactions of these blocked mercaptosilicon compounds are triggered by exposure to an appropriate deblocking agent.
