Epoxy polymers: Glass transition/cure degree correlation

Journal of Thermal Analysis, 1985
The correlation between the glass transition temperature,Tg, and the cure degree, α, of epoxy polymers has been analysed on the basis of an extension of the Vogel-Tamman-Fulcher equation for the viscosity of polymers and glasses.

Polymerization efficiency of chemically cured and visible light-cured orthodontic adhesives: Degree of cure

American Journal of Orthodontics and Dentofacial Orthopedics, 1995
The use of light-cured orthodontic adhesives in combination with the new generation of ceramic brackets has become popular from an esthetic standpoint. The purpose of this article was to evaluate the degree of cure (DC) of selected light-cured and chemically cured adhesives bonded to ceramic and stainless steel brackets. The optical properties of eight

Continuous 3D printing by controlling the curing degree of hybrid UV curing resin polymer

Polymer, 2021
Abstract To achieve high speed and high efficiency continuous 3D printing, interface adhesion between the cured resin and the bottom of the resin tank has to be overcome and fast stripping has to be achieved. In this paper, a method that combines low surface energy Fluorine membrane and low curing degree hybrid resin is proposed to achieve continuous
