Sealant, Gasket and Adhesive Applications of Polymers in Housing Construction

4 Sealant, Gasket and Adhesive Applications of Polymers in Housing Construction 

Sealants are elastomeric substances used to seal (or caulk) an opening or expansion/contraction joints in building structures against wind and water [40]. 

Sealants are also known as adhesives with lower strengths , and they mainly comprise synthetic elastomeric thermoplastic or thermosetting polymers (pigmented/unpigmented). 

Thermoplastic sealants are, in general, either preformed sealants or hot-applied polymeric sealants. 

Preformed sealants are pre-moulded from a range of materials (synthetic rubber, PVC) with different shapes (in tape, ribbons, beads, or extruded shapes), and are mainly used for glazing.
