Class Information
Number: 264/4.3
Name: Plastic and nonmetallic article shaping or treating: processes > Encapsulating normally liquid material > Liquid encapsulation utilizing an emulsion or dispersion to form a solid-walled microcapsule (includes liposome) > With treatment subsequent to solid wall formation (e.g., coating, hardening, etc.)
Description: Subject matter wherein solid-walled microparticles are subjected to a significant chemical or physical after-treatment, e.g., heating, formaldenhyde crosslinking, etc., the recitation of "hardening the formed microcapsule" is sufficient for placement here.
