These sealants and adhesives are of moderate elasticity, meaning that they are able to be stretched without breaking. Another, more technical term, is the modulus of elasticity. These products are of medium to high modulus.

It is important to select the correct elasticity for the application’s anticipated movement of substrates. For example, in many construction bonding applications, a high modulus product with slight elasticity is preferred, as the adhesive will be able to accommodate slight movements and vibrations, but still retain high bonding strength.

These products have moderate elasticity, which make them ideal for joints without too much movement, or for bonding applications.
