About Sealant Flexibility

Structural Sealants


These structural sealants combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility. They’re non-sagging, so they won't drip from vertical and overhead surfaces.
Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. For joints between dissimilar materials and in environments with wide temperature fluctuation, choose a sealant with a higher elongation or joint compression/expansion tolerance. For high-wear applications, choose a harder sealant for the most abrasion resistance.
