Joint Sealants
About Joint Sealants
This is a polymer-based seal used in building and construction design applications to seal and protect joints between two substrates. Handitech used it to seal joints, gaps and openings between two or more substrates to stop environmental elements that make available conditions that may lead to corrosion. It is designed to shield joint edges from corrosion in concrete. Expansion joint sealant for concrete structural joints.
Properties & Characteristic of Joint Sealants
- Many types of joint sealants with good properties are available. The basic
- Characteristic of a good joint sealant should be as follows.
