A sealant is a soft, pliable material that is used to seal cracks or joints where structural strength is not required.  These soft materials can accommodate building and civil engineering structure movement while assuring a durable, sustainable and above all functional tightness throughout their operational life. 

Sealants need to meet market requirements depending on function and location of the joint. The following information gives more detail on the types of sealants available from Bostik New Zealand. 

Polyurethane sealants cure by absorbing moisture from the air. Polyurethane sealants can be used for general construction sealing and caulking in which moderate movement can be expected. Typically, one-part polyurethane sealants are capable of ±25% joint movement. Newer polyurethanes have a lower - modulus properties, allowing them to seal joints with high amounts of dynamic movement. 

Hybrid sealants are the fast growing elastic sealant that uses the latest in adhesive technology. It combines a wide adhesion spectrum, paintability, bubble-free curing and applicability to damp substrates. In addition, hybrids products contain no isocyanates.
