Reducing Modulus of Sealants to Improve Durability

Source

The premise is that if one reduces sealant fatigue by lowering modulus while leaving other characteristics of a sealant unchanged, its durability will improve. Reducing sealant fatigue is seen as a positive consequence of lowering the modulus of elasticity of a sealant. The data shows the effect of incorporating a modulus modifier in one- and two-part (standard curing) urethane sealants and a one-part silane curing polyether sealant. This approach lowers modulus with no or minimum reformulation.
