A clean, shining look of any automobile or a floor always gives a good appeal to the eyes. Therefore, the market of adhesives and sealants is growing day by day. A wide variety of these products are available in the market today.
A sealant is a gluey material used to close small openings to prevent the penetration of air, gas, noise etc. They are corrosion resistant and are used in different industries like construction, automobile etc. There is a thin line of difference between adhesives and sealant is that sealants have a lower strength than adhesives.
There are a variety of sealants available in the market that includes acrylic and polysulphide sealant, pipe thread, cement, rubber, silicon, wood and epoxy sealant that are in one and two parts system. It exhibits hardness resistant to moisture oil, solvents etc. These can be made available in various formulations and are long lasting and are easy to use.
Another item available is the acrylic sealant that is easy to apply and is flexible having a variety of surfaces without primer. They have good low temperature flexibility.
In fact adhesives and sealants play a very important role in improving fire resistance of a variety of products, mostly testing the final product. The quantity of using these products is often a challenge.
The adhesives and sealants are also used in bonding the fuel cells which is the ultimate solution to global energy problems. There are various types of fuel cells and each of them has some or the other special characteristics that matches the application. It is a good source for the transportation industry.
Another type of sealant is characterized as polysulphide sealant generally used in joint sealant or glazing sealant. The polymerization is initiated at room temperature after mixing resin and hardener.
The rubber based adhesives and sealants exhibits high performance, having high adhesive strength made for bonding different materials such as automobile, electronics, construction etc.
There are various fillers also used with the adhesives and sealants that take up space. The various fillers can be
calciumcarbonate, alumina trihydrate, barium sulfate, and silica and kaolin clay.
The fillers used must be chosen to optimize performance. The focus before choosing the fillers and sealants must be on the
materials that give more leverage to achieve desired results.
