formation and release of hydrogen gas, and can be minimized by adding __by manufacturer like hydrogen absorber, Palladium.
- low molecular weight polyether - ethylene imine terminal group Tube 1. Base
- aromatic sulfonic acid ester Tube 2. Catalyst
used as modifier, to lessen the rigidity or increased the flexility of polyether. Tube 3. Thinner
is any of various polymers having the elastic properties of natural rubber and it comprise a group of synthetic polymer-based impression materials that are chemically cross-linked ELASTOMER
INELASTIC (3) Plaster of Paris Zinc oxide-eugenol Impression Compound
ELASTIC Condensation Silicone Addition Silicone Agar Polyether Polysulfide Alginate
