Abstract
The process of forming epoxy powder compositions with the participation of highly dispersed magnesium oxide in the preparation of compositions by extrusion mixing of components in the melt is investigated. It is established that highly dispersed MgO particles participate in the polymerization process and act as additional crosslinking units of defective regions of the polymer network, which improves the functional properties of epoxy powder compositions. Coatings based on modified compositions are characterized by high physicomechanical properties at low temperature curing (130 °С) and can be used to form protective coatings on heat-sensitive products.
