Stress relaxation studies on all samples revealed that, for Sealant A, two mechanisms affected modulus change; exposure without applied strain increased the modulus while additionally applied strain decreased the modulus. Only one mechanism that decreased the modulus was found...

... 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...
