EXOTHANE™ Elastomers - Sponsored Whitepaper

The enhanced properties of the EXOTHANE™ Elastomers, specifically the high percent elongation and toughness, suggest that these novel materials could be used for specialty applications or as functional additives to improve the durability of existing formulations.

Some of the most notable deficiencies of commercially-available resin materials and formulations are high volumetric shrinkage, high shrinkage stress and low conversion. Volumetric shrinkage occurs as monomer molecules react to form a polymer network that leads to a bulk contraction. This phenomenon is the cause of shrinkage stress. Shrinkage stress can cause separation of the formulation from the substrate. Low conversion is equated to leakage of uncured or residual monomer, which can be associated with allergic reactions and sensitization.As conversion increases, the amount of uncured monomer decreases and so would the likelihood of monomer leakage.
