New Silane-Terminated Polymers for Sealants and Adhesives

摘要

When building components meet, they inevitably form a joint. It is generally sealed to keep water, air, dust or other media out. Here, the difficulty lies in the detail. The gap that needs to be bridged can vary widely, depending on to what extent the components expand or contract when exposed to heat or cold. So, for the joint to remain permanently sealed, the sealant must be able to accommodate the changes in joint dimensions again and again without tearing or detaching from the surface.
