What are Joint Sealants?
Joint sealants are polymer-based gaskets that are commonly used in building and construction design applications to fill and protect joints between two substrates. They are used to seal joints, gaps and openings between two or more substrates to prevent environmental elements that provide conditions that may lead to corrosion. Joint sealants and other joint filler boards are designed to protect joint edges from corrosion in concrete and clay tiles.
WHY JOINT SEALING IS IMPORTANT?
The building blocks of construction such as the concrete slab, the glass facade element, the roofing membrane and the metal cover – generally do not let water, moisture or air enter the building or structure. Construction chemical suppliers say that it is at the joints where a building is weakest to leakage. Only correctly specified and professionally applied joint sealants will manage to keep a building or a structure sustainably tight during its entire lifespan.
PROPERTIES OF GOOD SEALANT
The basic properties of a good sealant should be as follows:
• The sealant should have a good bond with building materials.
• The sealant should be soft.
• It should be flexible.
• It should not be affected by the weather changes.
• It should be strong against stress and stress relief cycles.
To accommodate structural and thermal changes, there are different types of joint sealants available in the marketing. The design of joint sealants is dependent on the substrates used to provide the joints. Here are the various types of Corrotech joint sealants available at MCT.
Corroseal PS749 – Corroseal PS749 is a two-component polysulphide. This joint sealant is used for sealing movement & construction joints from 5 to 50 mm width in concrete, masonry, metal and many other substrates. It is supplied in pre weighed packs in gun or pouring grades, ready for onsite mixing and use, giving consistent properties and performance.
Corroseal LS – Corroseal LS is a flexible polyester cable loop sealant. It is typically used for sealing horizontal joints around runway or apron lights, and cable slots or loops in concrete or asphalt roads and pavements, particularly for traffic signals, electronic barriers and traffic counters.
Corroseal RB – Corroseal RB is a rubberized bitumen mastic sealant. This sealant is ideal in low movement & construction joints from 5 to 50 mm width in asphalt, concrete, masonry, metal and many other substrates.
