Оценка кинетики отверждения полиэфирной смолы во времени стандартными и нестандартными методами

Evaluation of the curing kinetics of polyester resin and polymer concrete on its basis was carried out in time by measuring the microhardness and the width of sclerometric grooves within one month. On the front and back sides of samples from polymer concrete using a laboratory sclerometer, scratches were applied at various load levels on the indenter. It is shown that the gelcoat layer on the surface of the polymer concrete increases the scratch resistance, with the greatest sensitivity to the presence of gelcoat established at low loads on the indenter.
