Abstract: The present invention is related to a curable composition for dental impression comprising: a curable base composition and a surfactant system comprising a first surfactant, which is at least one compound having the formula (I) and a second surfactant, which works synergistically with the second surfactant so as to permit the composition to surprisingly have a lower contact angle; these results are reached with relatively low concentrations of biodegradable surfactants.

Abstract: The present invention is related to a curable composition for dental impression comprising: a curable base composition and a surfactant system comprising a first surfactant, which is at least one compound having formula (I) and a fluorotelomer having formula (II), which works synergistically with the fluorotelomer so as to permit the composition to surprisingly have a lower contact angle; these results are reached with relatively low concentrations of biodegradable surfactants.
