Polysulphide Sealants For Joint Sealing
Dec 26, 2017

A sealant is a viscous material that changes state to become rubber like compound, once applied, and is used to prevent the penetration of air, gas, noise, dust or liquid from one location through a barrier into another. Typically, sealants are used to close small openings that are difficult to seal with other materials, such as concrete, drywall, etc. Desirable properties of sealants include insolubility, corrosion resistance, and adhesion. Uses of sealants vary widely and sealants are used in many industries, such as construction, automotive and aerospace.

As we know that concrete structures are provided with joints and these joints are to be sealed with an elastomeric sealant according to its durability.

The sealants should be in either thermoplastic or thermosetting in nature depending upon the specification provided.

Polysulphide sealants are the best sealants to be used for joint sealing. Moreover the performance and durability of sealant always depend on the quality of sealants or some times on the design of the joint. Proper joint design and best quality sealant are needed for obtaining longer durability.
