Vital Sealant Properties You Must Know
Clearly, polysulphide sealant is the most widely used sealant when it comes to filling and protecting joints, gaps, and voids in construction. But there are other sealants too in the market that although have differential properties, serve the same purpose. Whichever sealant you buy for your building structure it is important to know and comprehend its essential properties first so that you do not buy the wrong product. Let us read about them below.
Vital Sealant Properties You Must Know
Weather Resistance
A superior quality sealant is always resistant to sun, moisture, or other extreme temperatures. It performs aptly and as expected for the application.
Consistency
Sealants remain consistent in areas where they are applied, even on vertical joints as they have high viscosity. If a sealant has low viscosity, it can only find application in horizontal joints.
Hardness
High-quality sealants are hard and do not deform. However, with a high harness comes less flexibility, hence the user has to choose as per the application needs.
Adhesion
Sealants must have the required adhesion in order to adhere to the substrates they are applied to. Manufacturers like IWL provide adhesion details of sealants for various substrates.
Durability
Of course, they should be durable. Moreover, their durability and life cycle also depend on the way they are applied. If they are not applied well or are not suitable for the substrate, they won’t last long.
Elasticity Modulus
Low-modulus sealants find application in delicate surfaces. While high-modulus sealants are used in joints with minimum to zero movements.
Volatile Organic Compounds
These compounds are present in all sealants, in low or high concentrations depending on the manufacturer’s objective. Checking the VOC content is a must before sourcing the sealants.
Cost
The cost of sealants may vary based o their applications and performance levels. Keep in mind to buy the best quality sealant rather than pondering the cost and buying a low-quality material. Check out IWL India’s polysulphide sealants.
