Sealants for soundproofing in interior designing

Sealants are the substances that are used to block the passage of the openings in the materials .These sealants are used in construction for blocking dust ,sound and heat transmissions also. They have different properties of weak or strong , rigid or flexible, temporary or permanent. Some have the adhesive qualities and some doesn’t have.
The main difference between the sealants and adhesive is the sealants have the lower strength and higher elongation compared to the adhesives. The main objective of the sealants is to seal up the assemblies and joints they need the sufficient adhesion to the substrates and environmental conditions to remain bonded over the required lifetime of that assembly they need a adequate flexibility and elongation when they are used between the substrates for different thermal co efficients of elongation during the stress.
The sealants contains the inert filler material that are used to formulated the elastomer to provide the flexibility and elongation of the sealants they have a paste consistency which allow to fill the gaps of the substrates low shrinkage application is also required. And amny of the adhesive technologies can be added to the sealants.
Sealants falls into a category of higher strength adhesive at one end and extremely to lower putties and caulks at another end. Since these caulks and putties serve only one function they will take up the space and fills up the voids although sealants are not strong but they carry different properties they are capable of sealing the glue line they also capable of keeping the moisture in or out of the substance which is used they act as a thermal and acoustical insulations and provide the qualities of fire barriers also and sometimes even electrical properties they carry the sealants are also used for smoothing and filleting they can do many jobs at one:
They carry three main properties such as:
They up the gaps between two or more substrates.
The physical properties of the sealants forms the barrier itself and the adhesion to the substrate.
It provides the sealing properties for a long time , environments and service conditions .
Sealants are classified into 3 major forms:
One component sealants: chemical technologies include acrylic solvent-based, butyl solvent-based, latex water-based, silicone and urethane; no special equipments are required and packed in a cartridge.
Two components sealants: it is the combination of two parts ,a base component and activator component. The activator is added to the base component before a period of the time used in application.
Sealant tapes: sealant on a flexible backing; types include butyl and silicone tapes and urethane tape.
