Standard flowable composite formulations incorporate fine air bubbles into the material. When photo-polymerized these air spaces result in uncured composite internally, leading to internal structural weaknesses and the development of micro-fractures.
The ENA HRi Flow formulation eliminates air bubbles, resulting in superior physical properties.
