Best Joint Sealent and Bridge Adhesive in Bangladesh

Joint sealants are used to seal joints and openings (gaps) between two or more substrates and are a critical component for building design and construction. The main purpose of sealants is to prevent air, water, and other environmental elements from entering or exiting a structure while permitting limited movement of the substrates. Specialty sealants are used in special applications, such as for fire stops, electrical or thermal insulation, and aircraft applications.

Sealants are used for a variety of commercial and residential applications. Common sealants include silicone, acrylic, urethane, butyl, and other polymer types. Various formulations have been developed over the years, which meet performance specifications established by industry standards, as well as for the specific and unique needs of the end user.

Conventional joint systems for expansion joints on industrial floors are based on polyurethanes, silicones, MS polymers or polysulphides. These are usually less resistant than the adjoining coating and vulnerable to chemical attack, quickly becoming brittle and needing to be repaired within relatively short intervals. Mycoflex Resyst can eliminate this vulnerability. MC-Bauchemie’s product system consists of prefabricated mouldings made from a special polymer foam that is highly resistant to chemical attack, mechanical stressing and permanent water exposure. It delivers a thoroughly reliable joint system for floors and expansion joints, even where components suffer significant thermal expansion and heavy mechanical wear and tear. This makes the joint system particularly suited to a wide range of industrial floor applications, especially the chemical and oil industries and in the sewage treatment sector.

Types of Joint Sealent:

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.

Benefits of Joint Sealent:

• Ability to withstand high & low temperatures far better than orgamic rubber
• Joint sealent are an excellent insulting material
• Highly durable and form tight seals
• Great asthetic finish
• Water repelling material
• Good thermal stability
•  Low chemicals reactivity
