Polyfilla is a 2 component epoxy: a resin and a hardener (with
triethylenetetramine as a base), along with a white filler; the
technical fiche given by the Polyfilla company (Polyfilla Products
S.A.) does not tell the nature of the filler, but it 's probably
chalk. The use however is not advised, it gets very hard after a
period of time and the consistency is not flexible, so it cracks.
Depending on the use it is poorly reversible.
