Properties of Two-Component Installation Materials

Abstract

A two-component (2C) system is a system of two precisely coordinated reactive components which are stored and transported separately from one another. They are mixed directly before application and then react to construction materials with defined properties, largely independently of external influences. As the two components – usually referred to as A and B – are specially adapted to one another, they generate reaction products which can meet the highest requirements if used as directed. Due to the high reactivity of their individual components, two-component systems require strict adherence to the stipulated health and safety instructions. After curing, the products are physiologically and ecologically harmless. In principle, hydraulically curing mineral systems (cement-based or calcium-sulphate-based dry mortars) as well as reactive resins are considered two-component systems. The term ‘two-component system’ is often used only to refer to reactive resin systems, though. The following information is limited to the latter group.
