Our advantage — amine hardeners
Currently, in the production of composite reinforcement, most manufacturers use anhydride hardeners as a binder

We use exclusively amine hardeners, because they provide higher physical and mechanical characteristics of the cured systems, excellent water resistance and alkali resistance, as well as significantly higher resistance to elevated temperatures
Protected from corrosion
Tests of composite reinforcement on amine hardeners to determine the resistance to alkalis show a drop in strength by an average of 11%, on individual samples less than 3%
WE USE
Amine hardeners
Composite reinforcement based on amine hardeners is more resistant to alkaline influences, as well as prone to elongation
Allowed for use for prestressing
Anhydride hardeners
MOST MANUFACTURERS USE
GOST 31938-2012 requires that the reduction in the tensile strength of composite reinforcement after exposure to an alkaline environment is no more than 25%. For reinforcement with anhydride hardeners, this indicator is more than 50%
Subject to corrosion
Weak corrosion resistance of composite reinforcement can lead to rapid destruction of building structures and accidents
Can not be used for prestressing
