Abstract
A method for microencapsulating a core material, such as a blowing agent, in a single shell which has demonstrated to be challenging to microencapsulate as an individual component with a single-shell wall deposition using conventional techniques. Single-shell microcapsules of the blowing agent can be formed, minimizing steps involved in the present microencapsulation technique. Also, microcapsules formed by this method provide increased performance in end-use products, including but not limited to characteristics such as product shelf-life, ease of use, and greater expansion properties. A method of making a coating formulation including the microcapsules is further provided, as well as a fastener including the coating.
