Viscoelastic properties of elastomeric impression materials. II: variation of rheological properties with time, temperature and mixing proportions.
The variation of torsional shear modulus with time for several commercial elastomeric impression materials has been determined. The effects of mixing proportions and temperature on rheological properties are presented. The relevance of these properties to the actual use of these materials are discussed.
