Excellent Adhesion and Flexibility

With more than 500% elongation at break and superior tensile strength, MYK SEALARM PU-GREY reliably accommodates joint movement and provides long-lasting sealing. Its elasticity ensures joints remain intact and watertight, even under thermal expansion or structural shifts, making it an excellent choice for demanding construction projects.


Easy Application and Rapid Curing

Supplied in a convenient 600 ml sausage, this polyurethane sealant is applied using a standard caulking gun. It skins over in about 60 minutes and achieves full cure in roughly 24 hours at 23C and 50% relative humidity, delivering rapid project turnaround and minimal downtime for construction teams.


Versatile and Weather-Resistant

MYK SEALARM PU-GREY is compatible with a wide range of substrates, including concrete, masonry, metals, wood, and some plastics. Its weatherproof and UV-resistant formula withstands service temperatures from -40C to +80C, making it suitable for both indoor and outdoor applications across India.
