Abstract:
A modeling paste which can be applied to a substrate as a thick layer and then subjected to a treatment which cures the paste so that it forms a machinable layer on the substrate, the modeling paste comprising(1) a matrix material which(a) provides a continuous phase, and(b) comprises at least one precursor which, during said treatment, takes part in a reaction to form a crosslinked polymer;(2) a latent material which(a) is not part of the continuous phase, and(b) comprises an active chemical ingredient which, during said treatment, takes part in the reaction to form the crosslinked polymer, and whose concentration in said reaction is increased by said treatment to an extent such that the modeling paste cures to form a machinable layer;(3) a filler; and(4) an elastomer which is not part of the continuous phase.
