4. Composition and properties
WILLKAT® FV 120 /1 component A is a special aqueous sodium silicate with additives. Component B is a modified polyisocyanate, that gives the flexible characteristics to the final product
During the reaction the A component cures to a silicate, while a solid polyisocyanate/polyurea is formed from the B component.
Together A and B form a penetrating network, a tough elastic, non foamed silicate resin (organomineralresin).
The component A has to be poured completely into the bottle with component B. After closing the bottle both components are thoroughly mixed by shaking the bottle until a homogeneous product free of streaks is formed.
The product has to be applied by the dropper bottle and smoothed with a spatula.
The usual range for screed renovation is approx. 6 running meters / set with 2x300 ml content, assuming that the crack width is approx. 4 mm and the crack depth is approx. 25 mm
