Coated Articles Formed Of Microcapsules With Reactive Functional Groups

Patent No. EP1984178 (titled "Coated Articles Formed Of Microcapsules With Reactive Functional Groups") was filed by Outlast on Jan 25, 2007. The application was issued on Aug 7, 2019.

Patent Summary

Thermal-regulating fabric coating that chemically bonds microcapsules to prevent premature leakage and maintain breathability. Conventional blends wash out easily, causing stiffness and skin irritation. This design uses a binder with a very low glass transition temperature and microcapsules sized 1–15 microns. The capsules are covalently linked to the substrate and binder using groups like amides or esters. Some capsules also bond directly to the fabric, while others cross-link the binder matrix. The coating contains phase-change materials that absorb heat when warm and release it when cold, keeping the fabric flexible and soft without blocking moisture.
