Hybrid Tri-Cure Organo-Silicon Coatings for Monument Preservation

A coating system integrating three distinct chemistries was developed to protect materials used in monuments and construction. Initial curing is achieved using a UV-initiated thiol-ene reaction form non-impressionable/non-sticky surface. Second, amine/epoxy reactions firm surface adhesion give mechanical strength through consolidation. Third, alkoxysilane sol-gel integrates the siloxane network while adding thermal stability, hydrophobicity, hardened The final design utilizes photoacid generator increase speed of second third steps. can be applied by spray, dip, or wipe on methods exhibits rapid non-impressionable (as fast as 10 min) that resists graffiti environmental conditions, stored single-component with pot life exceeding six months. series experiments were determine properties durability, including field testing accelerated weathering.
