Sealant is a material which is used to seal the joints between materials such as concrete, glass, aluminum, masonry wall etc. In general joints are provided in the structures to prevent the damage produced by stresses.
Different types of sealants with good properties are available. The basic properties of a good sealant should be as follows.
- The sealant should have good bond with building materials.
- The sealant should be soft.
- It should be flexible.
- It should not affected by the weather changes.
- It should strong against stress and stress relief cycle.
Concast™ J-Seal PS Two Component High-performance Polysulphide Joint Sealant
Concast J-Seal PS 2CP is a two component sealant based on Polysulphide liquid elastomer. It consists of a ‘base’ compound and ‘accelerator’ (Curing Agent). When the two components are mixed together prior to application, a chemical reaction is initiated which cures instantly to a firm, flexible rubber like seal with excellent adhesion to concrete, masonry, wood, glass, acrylic and PVC plastics.
Concast™ J-Seal PU Single Component Polyurethane Joint Sealant
Concast J-Seal PU1 is a high performance, single component, moisture curing, polyurethane sealant ideally suited for a number of construction applications. It is able to accommodate thermal and structural movements without breaking/ loosing the adhesion to the structure elements. These sealants thus retain their original functionality throughout their whole life cycle and provide long term tightness.
The sealant is ASTM C 920, Type M, Grade NS, Class 25, use NT, T, A, M, O* and ISO 11600 (Type F 20LM), ISO 11600 (Type F 25HM) compliant.
