Mapeflex PB27 is a two-component self-levelling flexible sealant made up of hydrocarbon and polyhydric alcohol resins (part A), and a special isocyanate - based hardener (part B). The setting time and pot life depend on the ambient temperature. The working time of the mixed product, at a temperature of +23 degrees C, is approx. 45 minutes.
The two-parts are carefully mixed together to obtain a flowable self-levelling black paste.
In order to ensure the correct function of the sealant, Mapeflex PB27 must be able to stretch and contract freely. Therefore, Mapeflex PB27 must adhere perfectly only to the sides of the joints and not to the bottom, and the depth of the joint must always be less than the width.
