Market Evolution
Initial use of waterborne silicones began in the 1990s limited to fabric softeners and textile coatings. Early formulations suffered from lower performance relative to solvent alternatives. Development improved through the 2000s when emulsion stability and film forming capabilities were enhanced. Breakthrough in polymer chemistry and surfactant technology facilitated higher solid content and longer shelf life. Adoption expanded into construction sealants and coatings in the 2010s. Recent years saw development of hybrid systems combining waterborne silicones with acrylics, polyurethane, or epoxy resins. Innovations in nanoparticle‑reinforced silicones brought improved water resistance and durability. Advances in encapsulation and self‑healing coatings occurred through R&D collaboration in North America and Asia.
