JH70 2K Joint Sealant

Polyurea joint filler technology has playing an important role in meeting the increasing need for a faster curing sealant in the construction industry. The system is self leveling, 100% solids, two component, polyurea joint fill and crack repair material . Designed to fill cracks, contraction joints, control joints or new construction joints on new or old concrete. The system penetrates into crack and prevents leakage and deformation of concrete. Product cures rapidly and consistently in applications ranging from -18°C to 65 °C. Applications can be reopened to vehicle or foot traffic in 1 hour. Product perform well at cold temperatures and resistant to most chemicals.

Properties

%100 solids , VOC free. Fast setting formula reduces service and repair time. High elongation and flexibillity. Moisture and temperature insensitivity. Suitable for filing cracks to reduce the rate of deterioration. Cures at ambient temperatures as low as -18°C. Remains flexible at low temperatures. Abrasion and impact resistance.

Applications

Concrete filling and crack repair. Filling concrete construction and control joints. Joints in parking lots and garages. Joints in roofs, balconies and pavements. Joints in airports and parking aprons. Joints in cold storage and manufacturing facilities. Joints in industrial floors.
