Which statement below is incorrect regarding elastomeric impression materials?

Show Answers

Materials mixed in a single step exhibit greater viscosity.Shear thinning affects the viscosity of non-phase impression materials.Incorrect mixing can lead to permanent distortion of the impression.Using the putty-wash technique minimizes dimensional changes during setting.

Explanation

Option A is false because single-step mix materials do not necessarily have higher viscosity. Shear thinning influences the viscosity of non-phase materials, improper mixing can cause permanent deformation, and the putty-wash technique helps reduce dimensional changes during setting.
